Main features

Micropro is a microprocessor controller designed to control fan coils of the éstro series. Together with the Micropro version for in built installation there is also the MicroproD wall-mounted version.

Main functions and equipment: • Regulation of the air temperature via the automatic variation of the fan speed.

• Regulation of the air temperature via the on-off switch of the fan at a fixed speed.

• Time function (not available for MicroproD).

• Control of ON-OFF valves for two or four pipe systems.

• Control of the electric heater as t integration or replacement of the heating circuit with delayed fan stopping.

• Cooling/Heating switching mode in the following way: ♦ Manual – in-built ♦ Manual - remote (centralized) ♦ Automatic – based on the water temperature ♦ Automatic – based on the air temperature

It is also equipped with: • Free contacts for external enabling signal (i.e.: reed contact, remote ON/OFF switch, proximity contact

etc.) that may enable or disable the unit. (closed contact = OFF; open contact = ON) • Free contacts for the centralized Cooling/Heating switching system. (closed contact = Cooling; open

contact = Heating) • Water temperature probe (optional for MicroproD) • Air temperature probe.

The control panel is made of: • Operating mode selector, to turn the fan coil on and off, to choose the type of operating mode

(automatic or at fixed speed) and to control the electric Heating. • Cooling/Heating selector• Operational LEDs indicating the current operating mode in use. • Thermostat to control the room temperature.

LED indicators. The various combinations in which the LED light up indicate different procedures and operating status of the controller:

Blue LED lit Indicates that the Cooling mode is running. The fan coil is running or waiting for an input from the thermostat.

Red LED lit Indicates that the Heating mode is running. The fan coil is running or waiting for an input from the thermostat.

Blue and Red LEDs lit Indicates that the fan coil has received no enabling signal: The water temperature doesn’t enable the air cooling or heating functions (see “Enabling signal based on water temperature”) or the temperature of the air is within the neutral zone (see “Automatic Cooling/Heating switching mode based on the air temperature”).

Fig.2

FC66000775 - Rev.04 5

Note: How to realise the operating mode when an enabling signal is missing (Blue and Red LEDs lit):

When the blue and red LEDs are both lit (no enabling signal, see previous section above), to check which operating mode is selected, turn the knob of the thermostat until one of the two LEDs starts to flash and then remains lit. This LED points out the operating mode selected (Blue = Cooling - Red = Heating). Once the operating mode has been established, turn the thermostat back to the desired position.

Double flashing of the blue LED This means that the thermostat has sent an input to the fan coil for it to start in Cooling mode. It flashes when the room temperature and the conditioning temperature set are the same: The temperature of the air in the room can be seen at any time on the thermostat range by turning the knob of the thermostat.

Double flashing of the red LED This means that the thermostat has sent an input to the fan coil for it to start in Heating mode. It flashes when the room temperature and the heating temperature set are the same: The temperature of the air in the room can be seen at any time on the thermostat range by turning the knob of the thermostat

Description of the operating modes

Manual in built Cooling/Heating switching mode

❄⇔✺MThe microprocessor controller is pre-arranged to operate manually in the desired mode. It is enabled by pressing the selector key. The blue (Cooling) and red (Heating) LEDs point out the operating mode selected.

Manual remote Cooling/Heating switching mode

❄⇔✺MDThe microprocessor controller is pre-arranged to operate manually and remotely in the desired mode. This mode is carried out by connecting the system to a remote switch. Use the special terminals on the electronic PCB of the Micropro system.

Automatic Cooling/Heating switching mode based on the water temperature

❄⇔✺H2OThe microprocessor controller automatically selects the Cooling or Heating mode based on the temperature of the water and according to the following logic:

Water temperature < 17°C: the Cooling mode is set Water temperature > 39°C: the Heating mode is set Water temperature between 17°C and 39°C: the system is disabled

Warning: The water temperature probe is an optional accessory for the MicroproD version.

See figs. 14÷20 of this manual for the assembling instructions of the water temperature probe.

Automatic Cooling/Heating switching mode based on the air temperature

❄⇔✺airThe microprocessor controller automatically selects the Cooling or Heating mode based on the temperature of the air compared to a neutral temperature interval (Neutral zone) centred on the set value of the thermostat.

Warning: When this function is selected, the temperature range of the thermostat refers to the values indicated in fig. 3, both for the Cooling and the Heating.

FC66000775 - Rev.04 7

Selecting the extempt of the neutral zone

The neutral zone is a parameter related to the “Automatic Cooling/Heating switching mode based on the air temperature” function. The neutral zone is a temperature interval astride the set temperature: When the air is warmer than the top limit of the neutral zone, the Cooling mode is selected. When the air is cooler than the lower limit of the neutral zone, the Heating mode is selected.

The following figure illustrates an example with: Neutral zone = 5°C Set room air temperature = 21°C For temperatures above 23.5°C the Cooling operating mode is selected For temperature below 18.5°C the Heating operating mode is selected.

Fig. 4

Micropro is used to select the extempt of the neutral zone at 2°C or 5°C in order to obtain respectively a more or less precise control of the air temperature.

Time function

The time function is used to start the fan at medium speed for 2 minutes at regular intervals (every 10 mins.) once the room temperature has reached the level set on the thermostat. It ensures the constant monitoring of the air temperature in the room. It is only used in summer and only if the enabling signal of the water temperature probe is positive. The time function cycle is also executed when the controller is powered (first start-up or voltage reset). Warning:The thermostat and the operating mode selector switch are disabled when the time function is in use. The time function can be used only for units without valves and only in summer. The time function function is not foreseen for the MicroproD version.

Electric heater control

The thermostat controls an Electric heater as integration or replacement of hot water heating system. When the operating mode selector switch is turned to and the Electric heater is turned on, the fan runs continuously at medium speed. For safety reasons the fan is turned off 2 minutes after the Electric heater is turned off, whether this occurs when the desired air temperature is reached or when the Electric heater is turned off manually using the operating mode selector.

Warning:The fan runs only at medium speed when the Electric heater is turned on.

Fan coil enabling system based on the water temperature

The microprocessor controller starts the fan coil according to the following logic based on the water temperature that is detected by a dedicated probe:

Water temperature < 17°C: Cooling mode enabling signal Water temperature > 39°C: Heating mode enabling signal

In installation with the Electric heater, the same probe sends the enabling signal for the Electric heater to turn on according to the following logic:

Water temperature < 39°C: Additional Electric heater enabling signal (This enabling signal is sent only if the operating mode selector switch is turned to ).

Warning: The water temperature probe is an optional accessory for the MicroproD version.

See figs. 16÷20 of this manual for the assembling instructions of the water temperature probe.

Warning: if the desired configuration does not include the Electric heaters control function and the operating mode selector switch is turned to the Electric heater symbol, the fan coil will continue to run “automatically” and will regulate the air temperature by means of the fan.

Installation on the support and on the fan coil The Micropro controller can be fitted on both sides of the fan coil using a support and a frame cover.

1. Unscrew the four screws hidden behind the hatches at the end of the grid and remove the fan coil cabinet (fig.6).

Fig.6 2. Remove the blank plastic tabs from one of the two slots of the support to be able reach the “fast-on’s”

of the Micropro unit to be used (Fig.7). (The fast-on’s will face one of the support slots, depending on whether the controller is to be fitted on the RH or LH side of the fan coil).

3. Feed the cables of the probes in one of the slots of the support and secure the support and controller together using the two screws supplied (Fig.8). (Fig. 8 illustrates the installation of the support and controller when the controller is fitted on the RH side of the fan coil. If the controller is fitted on the LH side of the fan coil, the support is to be turned by 180° compared to the drawing).

Fig.7 Fig.8

Warning: Ensure that all the terminals required for the electrical connections foreseen in the configuration chosen (valve, Electric heater, external contacts etc.) can be accessed even after the support has been fitted (see the relative wiring diagram). If this is not the case, remove the protective blank tabs from the base of the support.

4. Complete the electrical connections according to the wiring diagrams provided herein. 5. Once the electrical connections have been completed, it is advisable to execute the autodiagnosis

procedure to check if all the outputs are efficient before you end the installation of the Micropro controller (outputs of the fan at various speeds, of the valves and Electric heaters if installed): Refer to the next section of this manual.

6. Assemble the controller-support unit on the fan coil using the bayonet fittings (Fig.9). 7. Warning: Place the air temperature (black) and water temperature (white) probes (Figs.11÷18)

following the instructions given in the relative sections of this manual.

Autodiagnosis procedure

To check the correct operational efficiency of the Micropro controller, when installing it or to search for possible faults, all the outputs foreseen can be operated manually (fan, valves, Electric heater) thanks to the autodiagnosis mode. Proceed as follows to access the autodiagnosis mode and to run the tests:

1. Turn the operating mode selector switch to the “OFF” position. 2. Turn the knob of the thermostat anti-clockwise until it reaches the minimum temperature position: 3. Hold the Cooling/Heating selector down for at least 5 seconds. At this stage both LEDs light up. 4. Within 5 seconds, turn the knob of the thermostat clockwise to the maximum temperature position. The

red LED switches off and the blue LED remains lit to indicate that the autodiagnosis mode has been accessed.

Note: If you wait more than 5 seconds before turning the knob again, the autodiagnosis mode will be automatically exited.

5. In the autodiagnosis mode, each position of the operating mode selector switch corresponds to the simulation of an output, namely:

Position Output Terminals

AUTO Valve N-V ✤ Minimum speed N-V1

✤ Medium speed N-V2

✤ Maximum speed N-V3

Electric heater or second valve N-RE

By running through the various positions of the operating mode selector switch, the electronic controller outputs can be checked one after the other either by observing the relative component (valve, fan, electric heater) or by checking if the corresponding terminals are powered at a voltage of 230 V. Note: If the operating mode selector switch is not moved for more than one minute the autodiagnosis mode is automatically exited.

6. Exit the autodiagnosis mode by turning the operating mode selector switch to the “OFF” position.
