Safety InformationFollow all safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available. Follow all warnings and cautions in these instructions and attached to the unit. Consult applicable local building codes and National Electrical Codes (NEC) for special requirements.Recognize safety information. When you see a safety symbol on the unit or in these instructions, be alert to the potential for personal injury or death. Understand the meanings of the words DANGER, WARNING, and CAUTION. DANGER identifies the most serious hazards that will result in death or severe personal injury; WARNING means the hazards can result in death or severe personal injury; CAUTION identifies unsafe practices that can result in personal injury or product and property damage. Improper installation, adjustment, service, maintenance, or use can cause explosion, fire, electrical shock, or other condi-tions which may result in personal injury or property dam-age. This product must be installed only by personnel with the training, experience, skills, and applicable licensing that makes him/her “a qualified professional HVACR installer.”

Disconnect all electrical power before servicing unit to

prevent injury or death due to electrical shock.

Hazardous voltage! Disconnect all electric power including remote disconnects before servicing. Failure to disconnect power before servicing can cause severe personal injury or death.

Use copper conductors only. Unit terminals are designed to accept other types of conductors. Failure to do so may cause damage to the equipment.

Electric shock hazard. Can cause personal injury, or death, or equipment damage. This equipment must be properly grounded. Connections and service to the MicroTech II control panel must

be performed only by personnel that are knowledgeable in the operation of the equipment being controlled.

If the unit ventilator is to be used for temporary heating or cool-ing, the unit must first be properly commissioned. Failure to com-ply with this requirement will void the warranty.

Static sensitive components. A static discharge while handling electronic circuit boards can cause damage to the components. Discharge any static electrical charge by touching the bare met-

al inside the main control panel before performing any service work.

Never unplug any cables, circuit board terminal blocks, relay modules, or power plugs while power is applied to the panel.

For proper space control, and a more trouble free unit operation, it is important that End-of-Cycle (EOC) valves be used in all face & bypass damper equipped unit ventilators. An EOC valve is required for the wet heat coil in any unit ventilator that combines both a refrigerant coil and a wet heat coil. Use an EOC valve on all wet heat coils to minimize the potential for overheating.

For proper space control, and a more trouble free unit operation, it is important that an occupancy control means be used such

that the unit is placed into unoccupied mode during regular low load conditions such as nighttime, weekends and holidays.

Extreme temperature hazard. Can cause damage to system components. This MicroTech II controller is designed to operate in ambient temperatures from -40°F to 158°F. It can be stored in ambient temperatures from -65°F to 176°F. The controller is designed to operate in a 10% to 90% RH (non-condensing) and be stored in

a 5% to 95% RH (non-condensing) environment.

This equipment generates, uses, and can radiate radio frequen-cy energy and, if not installed and used in accordance with this

instruction manual, may cause interference to radio communications. It has been tested and found to comply with

the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable pro-tection against harmful interference when the equipment is

of the Local User Interface (LUI). The LUI provides a user adjustable security feature to protect against unauthorized or accidental control parameter changes. When networked with a BAS, additional parameters can be remotely read / set in addition to all those available on the LUI. This MicroTech II™ UVC is capable of complete, stand-alone unit control or it can be incorporated into a building-wide network using an optional plug-in communication module. Available communication modules include BACnet® MS/TP, LonMark Space Comfort Controller (SCC), and Metasys® N2 Open. Optional MicroTech II UV ServiceTool software can be used along with a PC to adjust operating parameters within the UVC. The UV ServiceTool software, while optional, is very useful for trouble-shooting and commissioning by allowing access to all user adjustable parameters within the UVC con-troller including many parameters not available through the LUI. The UV ServiceTool requires one of the optional plug-in communication modules as well as additional hardware components dependent upon which communications module is being used.Table 4: MicroTech II Unit Ventilator Controller (UVC)

It is an optional plug-in module that can be attached to the UVC via a 12-pin header and 4 locking standoffs to securely attach it to the UVC. It allows the UVC to inter-operate with another unit setup for master slave com-munication capability.

NOTICE Do not use master/slave units when a BAS will be connected to

the UVC.

Table 6: Master / Slave Network Variable Binding List

Plug-In Communication Modules

NOTICE Master/slave units will not be able to be connected with other

LonWorks devices without re-performing the network variable binding process in the field.

Master / Slave Control (Optional)When it is desirable to have multiple units within one space (i.e. conference rooms, library, stairwells, cafeteria, etc.), and there is no BAS present, it may be necessary to use one mas-ter unit connected to one or more slave units to ensure each unit within the space operates in a like manner. Each unit provided as a master or slave unit will be factory provided with one master or slave module. The factory will pre-bind network variables from the master and slave unit to provide the master / slave relationship. This binding process will in effect “marry” the master unit with its corresponding slave units for the life of the communication modules. The UVC has been provided with a configuration variable to select if slave units will operate as Independent (default) or Dependent slaves (see Table 6). Refer to Unit Ventilator Unit Control-ler LonWorks Communications Module IM 729 for wiring master/slave units.

NOTICE For proper master/slave operation, it is very important that the

factory correctly understand which units will be master, which units will be slaves, and which slaves will be connected to which master units at the job site. It is the responsibility of the pur-chaser when placing orders to ensure that the factory under-stands these things. It is strongly recommended that each group of master/slave units be purchased separately from stand-alone units, or other master/slave unit groups, to help ensure proper configuration.

NOTICE When using master/slave control, you cannot use the Cycle Fan

feature. Refer to the appropriate software model-specific opera-tion manual for more information on the Fan Cycle feature.

Make Electrical Wiring Connections

! WARNING To avoid electrical shock, personal injury or death, be sure that

field wiring complies with local and national fire, safety, and elec-trical codes, and voltage to the system is within the limits shown in the job-specific drawings and unit electrical data plate(s).

! DANGER Power supply to unit must be disconnected when making field-

connections. To avoid electrical shock, personal injury or death, be sure to rigorously adhere to field wiring procedures regarding proper lockout and tagout of components.

! CAUTION Use copper conductors only. Use of aluminum conductors may

result in equipment failure and overheating hazards. All wiring in right hand compartment must be class 1.

Field Wiring Harness LocationsThe low voltage field wiring connections have all been cen-trally located within the unit ventilator and are easily acces-sible.To simplify field connections, multi-pin plugs are factory pro-vided and pre-wired with short wire whips. Each of the wires in these wire whips is capped and should remain capped if not used. To make a field connection simply locate the correct wire, cut the wire cap from the wire and then connect the wire

Electrical Wiring Connectionswith your field wiring as shown in the field wiring diagrams.The unit mounted temperature sensor is provided with a quick disconnect plug (white) with wires numbered 101 and 102, and must be separated so that the unit mounted sensor is disconnected from the UVC. This disables the unit mounted sensor (see Figure 31).All low voltage field wiring connections must be run in shielded cable with the shield drain wires connected as shown in the field wiring diagrams.See the wiring diagram provided on the unit ventilator right front access panel.In addition, those unit ventilators equipped with optional elec-tric heating coil have electric heating coil power connections at right end only.Figure 25: Model AV - Field Wiring Whips with Caps Viewed from Right End Compartment

Field Wiring Remote Mounted Temperature SensorNote: Unit mounted room air sensors are recommended for

most situations to provide optimal unit performance. Unit mounted sensors are factory installed.

The low voltage field wiring connections have all been cen-trally located within the unit ventilator and are easily accessible.To simplify field connections, multi-pin plugs are factory provided and pre-wired with short wire whips (see Figure 30). Each of the wires in these wire whips is capped and should remain capped if not used. To make a field connection simply locate the correct wire, cut the wire cap from the wire and then connect the wire with your field wiring as shown in the two black wires coming out. This disables the unit mounted sensor (see Figure 31).All low voltage field wiring connections must be run in shielded cable with the shield drain wires connected as shown in the field wiring diagrams.The following are descriptions of the various options and features that may require field wiring.

NOTICE The UVC is configured for Basic and Expanded remote sensors.

To use the Deluxe remote sensor, you must reconfigure the UVC through the LUI. See the LUI menu reference in the appropriate OM for the correct settings. The setpoint will operate incorrectly otherwise when using a Deluxe remote sensor.

! CAUTION Static sensitive components. A static discharge while handling

electronic circuit boards can cause damage to the components. Discharge any static electrical charge by touching the bare met-

al inside the main control panel before performing any service work. Never unplug any cables, circuit board terminal blocks, re-lay modules, or power plugs while power is applied to the panel.

Remote Wall Mounted Sensors (Optional)All MicroTech II™ units come with unit mounted room air temperature sensors as standard. Units can also accept Re-mote Wall Mounted Room Temperature Sensors for remotely sensing room temperatures. Figure 37: Wall Mounted Temperature Sensor Wiring for Basic Wall Sensor

Remote Mounted Sensors


When Using A Remote Wall Mounted Temperature Sensor

NOTICE When using remote wall sensors on wall applications, where the

wall may influence the sensor reading, ensure that the remote wall sensor is thermally isolated from the wall.

If a decision is made to use a Remote Wall Mounted Temper-ature Sensor instead of the unit mounted room air sensor then placement of the Remote Wall Mounted Temperature Sensor is critical for proper room temperature sensing (see Figure 42 and Figure 43). The UVC is capable of using one of three remote wall mounted temperature sensors. The Basic Wall Mounted Temperature Sensor requires only 3-wires (plus shield drain wire) since the Basic Wall Mounted Temperature Sensor has no setpoint adjustment (see Figure 40). Figure 41 shows a 4-wire connection (plus shield drain wire) (see Table 20). It is recommended that additional wires be pulled to compensate for potential wire breakage or future options.

as the “default” option in the “UVC Input and Output Tables” will require field configuration to the UVC using the Local User Inter-face (LUI) in order to select the non-default external input option be used by the UVC. See the appropriate Software Model-Spe-cific Operation Literature for external input configuration instruc-tions. Do not make final connections of any external devices to the external inputs when using a non-default external option un-til you insure that the required configuration is complete. Dam-age to the equipment and or improper equipment operation can result.
