Exchanger package: EQrZ-05, lQrZ-05The ECONET® Exchanger Package contsists of one or two plateheat exchangers for connection to an external heating and/orcooling system. The Exchanger Package is delivered separatelyfrom the AHU and the ECONET® pump unit or integrated as standard for eQ range, see page 4 and 5. The exchangers are made of AISI 316 stainless steel, brazedwith pure copper. The tubes are made of high-pressure steel, painted with anti-corrosion paint. These are then insulated with Armaflex. The typical pressure rating is 31 bar (450 psi), and the typical temperature rating is 225 °C (437 °F). The heat exchanger package, the ECONET® pump unit and the external pipework must not exceed a total pressure drop of 40 kPa for maximum liquid flow. If the pressure drop is higher (a long distance between the components), it should

be taken into account when dimensioning the system.The pipe connections are male pipe threads from DN25 to DN50. The connections on the primary side against the plate exchangers are female pipe threads from DN25 to DN50.For dimensions DN65 and DN80, all connections are assem-bled flanges. The opening pressure for the delivered safety valve is 4.0 bar.All sizes of ECONET® Exchanger Package come with a speciallydesigned stand for mounting on a flat floor. The unit is delivered on a separate pallet.

packagingDuring transportation the ECONET® Exchanger protects in a appropriate package. This is totaly environmentally friendly and will discarded as secondary raw material.

Controller for heat recovery, frequency inverter and sensorsThe liquid flow in the ECONET® circuit is controlled by the frequency inverter/inverters for the pump/pumps and by an ECONET® controller. The controller is equipped with software that optimizes the circulation flow in the circuit for each operating condition. The software in the controller includes protection and alarm functions. The controller is Modbus, Backnet or LonWorks compatible.Modbus communication is intrinsic to the controller, and the Backnet and LonWorks module for the controller can be chosen as an accessory. The controller is mounted on the pump unit and is programmed with input data for the specific project. The frequency inverter for the pump is mounted on the pump unit, and cables are routed to the ECONET® controller and the pump. Necessary components such as pressure and temperaturesensors for the pump unit are included.

Components within the scope of the delivery are installed, and cables are routed to the ECONET® controller and the frequency inverter. The additional components/sensors needed for the calculation of energy recovery efficiency are included in the delivery, if specified, but mounting and cabling has to be done on site (not included in Fläkt Woods delivery).

packagingSuitable packaging protects the ECONET® unit during trans-port. This is fully environmentally compatible, and should be taken for central disposal as a secondary raw material.

CommissioningIn order to guarantee safe and optional functionality for ECONET® heat recovery, commissioning of each ECONET® system shall be carried out by accredited and trained personnel.

important!– Hold the pipe connections steady with a pipe wrench when tightening external pipes.– Use fl ax (hemp) and paste for sealing the connections.– Use sealings suited for anti-freeze liquids, such as ethylene glycol mixtures.




These plates indicate:

– Which of the plate heat exchangers are intended for heating and cooling.

– Inlet and outlet of the exchangers for primary heating and cooling.

– Pipes for connection to the ECONET® pump unit.

With the pipes installed correctly, the ECONET® Exchangerneeds to be protected from condensation with insulation onthe pipes to/from the primary systems. The shut-off valves on ECONET® Exchanger Package mustbe open when the system is running as normal.

The ECONET® must be connected to the pipe system sothat expansion forces or the pipe system’s own weight donot impose a load on the liquid connections. The liquid connections are provided with signs for the inlet and outlet.

General adviceFailure to observe general advice and installation require-ments can lead to the risk of damage.

flushing the pipe system– ECONET® pump units are cleaned and flushed at the factory. When flushing the remainder of the system, we recommend that the pump unit is disconnected and that the P40 pump is not used during flushing. It is extremely important to remove all the flushing/cleaning fluid from the system before filling with anti freeze as a chemical reaction can occur between the cleaning and anti- freeze liquids. As the coils cannot be emptied completely, they must not be exposed to the cold without anti-freeze.

filling– For optimal heat recovery, we recommend an approximate 25-35 % ethylene glycol mixture. Max mixture for the pump is a 40 % ethylene glycol mixture. The P40 pump should not be used when filling the system. Use a separate filling system, e.g. a separate pump with a non-return valve for filling the system, e.g. a hand pump.

– Fill until a static pressure of 1-1.5 bar is obtained on the suction side of the pump to avoid the risk of pump cavitation.


NB!If the ECONET® Energy Exchanger Packageis not integrated in the ECONET®-unit,the system need an additional safety valve.

NB!A purging valve must be fi tted at thehighest point in the system.

important!– Hold the pipe connections steady with a pipe wrench when tightening external pipes.– Use fl ax (hemp) and paste for sealing the connections.– Use sealings suited for anti-freeze liquids, such as ethylene glycol mixtures.

The purging, safety valve and drain connections are routed to the connection vessel next to the unit.





– Uses premixed anti-freeze liquid, type ethylene glycol/ water mixture. Prevent exposure to oxygen. When using concentrated ethylene glycol, it must be mixed with distilled water. The liquid must be mixed 24 hours in advance, so that the mixture will be free of micro bubbles. When filling with premixed liquid from a tanker lorry, ask for a flushing certificate.

– Mark the system with a label showing the actual flow, type of anti-freeze liquid, and concentration.

– Check for, and seal any leaks.

– Check that the anti-freeze liquid used has sufficient protection against corrosion, anti fouling and biological growth. Follow the instructions of the anti-freeze liquid manufacturer.

Air purging To get rid of all air in the system takes time, but is vital forthe performance. Use automatic air purge valves combined with manual air purge valves. Prevent the risk of contami-nation blocking the sealing and jeopardizing the shut-off function of the automatic air purge valve. Install a filter if there is a continuous problem with contamination. When the system is free of all air, make sure that all automatic aireliminators are OK and all manual valves are closed. Open and close all valves a couple of times. Close the by-pass valve and start the ECONET® pump. The pump should be run manually via the frequency inverter at maximum 30 Hz.

Under no circumstances must the pump be allowed to run dry, due to the risk of damage to the seals. Purge the air from the pump with its own purging valve. Make sure that the system pressure is maintained at 1–1.5 bar. Refillthe system continuously as the pressure decreases.If the pressure drops below 0.5 bar, there will be an A-typealarm from the controller.

Miscellaneous– Under no circumstances may the P40 pump be run dry. This is because the pump will be damaged by the air, resulting in leakage.

– The coils for supplementary heating/cooling have to be installed with separate shut-off valves. The total pressure drop for the heat exchangers on the secondary side must not exceed 40 kPa at the maximum liquid flow for a closed heat recovery circuit. A higher value should be taken into account when dimensioning the system. The purging, safety valve and drain connections must be routed to the connection vessel next to the unit.

– Use air purge valves that can handle micro bubbles (type Spirovent or Flamcovent).

– The vessel must be installed on the suction side of the pump (between the pump and the plate heat exchangers for supplementary energy) with a volume of at least 5 % of the total system volume and with 1.0 bar pre-pressure, 4.5 bar opening pressure.

– If the risk of cavitation is present on the suction side of the pump, it is advisible to install underpressure air eliminators.




Electrical connection and recommended fusesOnly the cabinet must be connected at disconnecting switch. Main power shall be 3x400 VAC. An electrician shall dimension the fuses for the pump according to the table below, and according to the site circumstances. Recommended minimum fuse for the cabinet is 10 A.

MAiNTENANCE iNTruCTiONs

General maintenance instructionsThe ECONET® unit does not require regular maintenance, other than observing the maintenance instructions providedby the anti-freeze liquid manufacturer. On the other hand, we recommend that regular performance checks are carried out to ensure that the unit operates as it should.

Check and pay special attention to the following:

- abnormal noise and vibrations, if any - corrosion on piping and brazed pipe joints, if any - loose pipe clamps, if any

warning! Avoid fl ushing with water near the electrical connections of the inverter and cabinet, since water could then seep into them and may cause a short circuit.

Cleaning the standard ECONET® coilsEven an effective air filter cannot remove all the dust from the air. The coating of dust on heating surfaces obstructs the air flow and gives poorer heat transfer. The coils must be kept clean, which is best performed with one of the following alter-natives or combinations of these.

1. Blowing clean with compressed air2. Blowing clean with steam3. Washing or rinsing with water. In the case of heating surfaces that are coated with grease, an appropriate detergent should be added.4. Vacuum cleaning After cleaning, all the fallen dust should be removed before starting the fan.The drip trays for the coils should be cleaned as appropriate.Also ensure that the water trap is cleaned and filled with water.

Cleanable coils for hygiene applicationsAll ECONET® coils with hygiene fins are fully cleanable accor-ding to the standards VDI3803 and VDI6022. This means that the coil can be cleaned with a high-pressure water system right through the core. The cleaning nozzle used for coilswith a fin pitch of 2.0-2.5 mm and deeper than six tubes is THD Power Clean manufactured by TECHNISCHER HYGIENE DIENST GMBH (E-mail: [email protected], web: www.thd.info).If the coil is six tubes deep or less, an ordinary nozzle can be used.

1. Make sure that no sensitive equipment, either inside or outside the unit, can be harmed by the water. Be extra careful not to damage the filter. If the unit has an empty section (EQTC), use the special drip plate to protect the rest of the unit.2. Clean the coil with a high-pressure cleaner. If the coil is deeper than six tubes, a THD Power Clean is needed to ensure a full cleanability.3. Point the nozzle at a 45-degree angle to have a free passage for the water jet through the coil. Make sure that the water penetrates the coil.4. Remove all dirt.5. Dry all surrounding parts in the unit. heaters, to give stable measurement values. GT00, GT10, GT20, GT21, GT30 are included when heat recovery measurement is chosen (option).

Anti-freeze liquidFollow the instructions from the anti-freeze liquid manufacturerregarding controls, maintenance, flushing and intervals for filling with fresh liquid, etc.

TAsk iNTErvAl, EACH yEAr

Liquid status Check the freezing point of the frost protection fl uid and follow the instructions from the anti-freeze liquidmanufacturer, controls of frost protection/quality, purity, colour, etc.Check the system pressure and top up with ethylene glycol mixture if necessary.Check the liquid fl ow against the balancing report.

Coils Check that the fi nned surface of the coils are not dirty and clean if necessary.

Water trap Check that water is present in the water trap for the exhaust air and supply air coils.

Air purging Check frequently initially. An annual check is suffi cient after the fi rst year.Shut off the pump and wait a couple of hours to make sure that the air bubbles have risen to the highest points in thesystem, where the air-valves should be present. Open/close all valves in the system so that all trapped air can be removed.

Valve checking Shut down the system and open/close every valve to make sure it has a smooth operation.

Pump seals Check the seals, and replace them if leakage is excessive.

functionThe heat recovery function is controlled by the ECONET®

control box. The specific functions for the AHU must be con-trolled by a separate controller (not included in the ECONET® delivery). The functions below describe the internal heat recovery function for ECONET®. The process and instru-mentation diagram for ECONET® is shown below.

ECONET®, extended delivery:Standard/normal: GT40, GT41, GT42, SV40, SV41, GP41, GF10, FO40.1, P40.1Advanced frost prevention: GT20, GH20, GT21Option: Double pump: FO40.2, P40.2Efficiency calculation: GT 00, GT10, GT20, GT21, GT30, GF20

Air handling unit not runningWhen the temperature GT41 is below +16 °C, the pump will start to operate at a constant low speed. When the liquid tempera-ture GT41 is higher than +17 °C, the pump P40 will stop.

start of the air handling unitWhen ECONET® receives a start-up signal, the pump P40starts to operate at a constant high speed after 3 minutes.After that the pump goes to optimal sequence.

Main functionECONET® is a part of the sequence to control the supplyair temperature to its set point.

Main functions of ECONET® control box (control sequence):• Cooling recovery, On/Off signal The pump P40 and frequency converter FO40 regulate the liquid flow to an optimal value for cooling recovery, and valve SV40 by-pass will then close. NOTE. The heat recovery signal must be 0 %.

• Supplementary cooling, On/Off signal The pump P40 and frequency converter FO40 regulate the liquid flow to the optimal value for supplementary cooling. SV40 will open. NOTE. The heat recovery signal must be 0 %.

• Heat recovery, 0...100 %, 0...10 V signal The pump P40 starts at minimum speed, the valve SV40 moves from open to closed, pump P40 goes from minimum speed to optimal speed (optimal heat recovery liquid flow).

• See below for twin-pump function and other support functions, further down.

frost and ice protection• Frost protection The liquid temperature at GT41 is prevented from dropping below the temperaure (approx -3 °C) for frost protection by regulating the liquid flow with the pump P40 and FO40 from optimal liquid flow to an increased liquid flow.

• Prevention against frost formation on the exhaust air coils (air side) When conditions are such that increasing the liquid flow is not sufficient, the valve, SV40, is controlled by the controller.

• Risk of frost formation When the liquid temperature GT41 falls below the A alarm value (approx. -10 °C), the A-type alarm is given.

• Ice protection: Protection against ice formation in the heat exchangers for supplementary heating/cooling (waterside) The liquid temperature at GT42 is prevented from dropping below the temperature (approx. 6 °C) for ice protection by regulating the liquid flow with the pump P40 and FO40 from optimal liquid flow to an increased liquid flow.

• Risk of ice formation When the liquid temperature GT42 falls below the A alarm value (approx. 2 °C), the A-type alarm is given.

Alarms• A-type alarms – Risk of frost formation, GT41 ( - 10 °C) – Risk of ice formation, GT42 (+ 2 °C) – Pump indication not the same as set value (conflict alarm, should run but does not, or should not run but does) – Low pressure in ECONET® liquid circuit – Internal hardware fault (heat recovery, GF10, GT41, GT42).

• Risk of frost formation When the liquid temperature GT41 falls below the A alarm value (approx. -10 °C), the A-type alarm is given.

• B-type alarms – One of the twin pumps has stopped when it should run.

Additional functions/options• Redundant pumps The ECONET® product version with redundant pumps has two pumps (P40.1 and P40.2) and frequency converters (FO40.1 and FO40.2) running in parallel. They are started and controlled in parallel. In the event of one of the pumps failing to run, the other pump continues to run automatically. Failure of one pump is indicated with the B-type alarm. The ECONET® unit continues running according to control signals with one pump only.

• Energy and Power calculation If energy calculation is specified, the ECONET® controller calculates an estimate of momentary power for – Recovered power – Additional power and – Power to the supply air The same momentary powers are accumulated to energy, and the following energy consumption values are calculated: – Recovered heating energy – Recovered cooling energy – Additional heating energy – Additional cooling energy – Heating energy to supply air – Cooling energy to supply air Calculated power and energy values are shown locally or via the communication interface. The calculated values are estimates only and are not calibrated. They can be used for general monitoring, but not as the basis for functions such as invoicing, for example.

• Efficiency calculation If necessary, additional measurement sensors (GT00, GT10, GT20, GT21) are installed and connected. The ECONET® controller then calculates the heat recovery efficiencies. The following efficiencies are calculated: – Supply air temperature heat recovery efficiency – Exhaust air temperature heat recovery efficiency – Momentary power heat recovery efficiency Due to measurement inaccuracies and small temperature differences the calculated efficiency values may exceed 100 %.

• Monitoring Two additional sensors (GF20, GT30) are used for dia- gnosing the operation of the ECONET® unit. – Exhaust airflow sensor: In order to evaluate heat recovery efficiency, the supply and exhaust flows must be equal. – Additional heating/cooling liquid temperature: The temperature level must be high enough to provide necessary additional heating/cooling.

ECONET® COMMuNiCATiON

In ECONET® there are currently three communication protocol options available: Modbus, LonTalk and BACnet. The following profiles define the communication interface when integrating ECONET® into a larger automation system.

Modbus rTuThe purpose of this section is to provide users with a means of familiarizing themselves with the configuration and use of Modbus within Climatix. More information can be found from the following documents:

• Climatix Modbus communication, slave mode Integration guide Fläkt Woods 8947GB 201006.• For the full specification of Modbus, refer to “modbus.org”.

Modbus RTU uses the RS485 bus as its communication medi-um. RS485 is a balanced line, half-duplex transmissionsystem that meets the requirements for a truly multi-point communication network, and the standard specifies up to 32 drivers and 32 receivers on a single (2-wire) bus. Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time.

Connection and configurationinternal interfaceRS485 (one of two Modbus interfaces always available on the basic controller) can be defined as either master or slave. The MODBUS-IP interface is always a slave and the internal RS485 Modbus interface is automatically set to master ifthe energy meter function is enabled.

External communication moduleA slave interface is always provided with the external Mod-bus communication module POL 902.Reference the above listed documentation for instructionsregarding commissioning.

ECONET® communicationFollow the instructions below to configure RS485 and Mod-bus. Settings in Climatix controller:1. Commissioning the unit with all settings before starting to configure Modbus.2. Log in with password 2000.

Navigate to menu “System overview – Communication – Modbus” to set slave address, baudrate and parity.

MENU SYSTEM OVERVIEW

COMMUNICATION MODBUS

3. Set the slave address for the device. (1-247, Must be unique within the system).4. Set Baudrate for RS485 (2400-38400).5. Set Parity for RS485 (None, Even, Odd).6. Set number of Stopbit for RS485 (1 or 2).7. Reset is required in order for the configured settings to take effect.

Note!Note that the temperature values are given in tenths of a degree Celsius. For example, 21 degrees Celsius is given as a numeric value 210. The numeric value must therefore be divided by 10 to arrive at the correct value.

ECONET® COMMuNiCATiON

lonTalkThe purpose of this document is to provide users with a quick and simple means to familiarize themselves withthe configuration and use of the Lon module on Climatix.More information can be found in the following documents:

• Climatix LON communication with POL906.00 Integration guide Fläkt Woods 8971 GB 2011.11.• For the full specification on LonTalk, please refer to the relevant standards.• You will also find more information about LonTalk at www.echelon.com and www.lonmark.org.

Lon communication is mostly used to integrate our ECONET® controller into a building management system. The goal of integration is to have the necessary dataavailable on the management PC, and to permit changes to the dedicated set points and stages. Use the commis-sioning workbook for ECONET® parameter settings. A special LON tool (for example NLStart Maker or NL 220 from Newron-Systems, or LonMaker from Echelon) must be used to configure the network, bind the variables and

to observe the snvt’s. The tool is also used to download the XIF and NXE files (LON image) for ECONET®. The image for ECONET® does not follow the image defined in Clima-tix LON communication with POL906.00 Integration guide Fläkt Woods 897GB 2011.11 (ClimatixAHU V1.x. loaded per default). The ECONET® image including two files (*.NXE and *.XIF) can be received from FWG. To communicate with the LON device, the PC must have a LON interface (card) installed as well. The ECONET® controller uses FTT-10A (Free Topology Technology) transceivers on a 78 kbs network. When deciding on the topology, relevant factors are themaximum cable length and the distance between the twofurthest bus subscribers. For details of the design, pleaseconsult the manuals mentioned above.

ConnectionConnect the LON module to the Climatix controller via the internal communication extension bus (plug connection on the left side of the controller) and follow the commissioning instructions as described in the manuals mentioned above.

settingsPush the “service pin” (alternatively execute software trigger for the service pin via the HMI if available in installed version) to send the neuron ID onto the bus as well as to identify the unit on the bus. The neuron ID can now be read with Climatix Scope from Climatix – LONInitEx or with Lon integration tools.

The elements and connections in the figure are:
