When working with “Dynamic Set”, by pushing SET again, the lower display shows “SEtd” (set dynamic), while the upper display will turn to the real setpoint value used to control the unit during this function. The SEtS or SETd appears only if the corresponding functions are activated.

18. HOW TO TURN A COMPRESSR IN OFF-LINE

A compressor can be turned off for maintenance or if it is in bad condition, without interfering with the normal cycle of the unit. Therefore, it is not necessary to stop the unit or the cycle.

1. Access the programming mode.

2. Find and then set the parameter CO12 = 1 (compressor 1 = OFF: out of the process control).

3. If necessary find and then set also the parameter CO13 = 1 (2

comp. / step 1stcomp.= OFF). To restore the compressor in the process control set the C012 and/or C013 parameter = 0.

19. DYNAMIC SET POINT

This function is useful to save energy or to run the unit with particular external air temperature condition. It allows to increase or reduce the setpoint with a positive or negative proportional offset. This value is combined with parameters Sd02 (for Chiller) or Sd03 (for HP), the 4...20mA analogue input or the outside air temperature. The Dynamic Set is enabled if:

- The parameters Sd01 = 1 and CF06 = 3, Pb3 probe configured as 4..20mA signal;

- The parameter Sd01 = 1 and CF07 = 3, Pb4 probe configured as outside air temperature. If the parameter CF07=3, by pushing and releasing the n key the upper display shows for 30 seconds the outside air temperature while the lower display shows Et (external temperature) label.

Pb3 probe configured as 4..20mA input signal (below)

20. ENERGY SAVING

It is daily or weekly configurable function with “hour time table” (if RTC on board) or depending from external digital input. During the Energy Saving cycle the real setpoint is calculated with the parameters ES10 and ES12: SET+ES10 for chiller, SET+ES12 for Heat Pump. The differential for the function cut-in/out is depending by

ES11 for Chiller and ES13 for Heat Pump.

20.1 Daily Programming

The daily programming is based on 7 parameters ES03>ES09 corresponding to the 7 days of the week; the value

1 enable the function for that day. Eg: ES03 = 1 means that the Energy Saving is activated for the whole 24 hours on Monday. If needed, repeat the operation for the whole week ES04(Tue)..ES09(Sun).

20.2 Hour Time Table (with RTC)

Based on two parameters: ES01 Energy Saving start hour and ES02 Energy Saving stop hour.

Eg: ES01 = 8.0 and ES02 = 10.0 it means that the Energy Saving is active from 8 to 10.0

for all the days of the week. Eg: ES01 = 23.0 and ES02 = 8.0 it means that the Energy Saving is active from 23.0 to 8.0

of the next morning; for all the days of the week. This function is disabled if the parameters ES01 / ES02 are both 0.

20.3 Energy Saving with External Contact

The function is enabled when the digital input, configured as Energy Saving, is activated by remote contact.

23. HOT START FUNCTION

Available only if the parameter CF01=1 air/air unit configured as heat pump, it allows to start the supply air fan only if the temperature of the condenser side is enough hot. This avoid to push cold air flow into the ambient.

23.1 Hot Start Fan Graphic Function

FA25 Set point of the Hot Start

Set the temperature value, detected by the Pb2 probe, under which the fan is keep locked. FA26 Differential of the Hot Start Set the differential to regulate the fan ON/OFF.

24. AUTOMATIC CHANGE - OVER

It automatic changes the chiller <-> heat pump functioning of the unit in correlation with the external temperature condition. The changing occurs only when the following condition are satisfied, otherwise the unit turns to stand-by:

1. CF01=1,3,5,7 (Heat Pump selected).

2. CF28=2 and CF07=3 (Pb4 external air temperature).

3. Pb4 probe is not faulty. The Change Over function is regulated by parameters: CF29 is the set point and it represents the Pb4 value under which the controller turns to Heat Pump mode. CF30 represents the temperature differential to turns to Chiller mode. The user can find helpful information by pushing and

releasing

n key so as the upper display shows the Pb4

value while the lower display shows Et label.

24.1 Graph Regulation of the Change-Over

When the temperature value is within the CF30 range, the changeover is allowed only though keyboard.

25. DEFROST FUNCTION

The defrost cycle is enabled only if the following condition are satisfied:

1. CF01=1,3,7 configuration chiller unit with heat pump.

2. dF01=1 defrost cycle enabled.

3. CF20=0 relay n°4 configured as reversing valve.

4. The unit is working in heat pump mode.

5. Pb3 or Pb4 must be configured as control

condensing probe without active faulty probe alarms. If only one of these conditions is not satisfied the defrost does not operate.

25.1 Forced Defrost

This function is enabled only if dF05 <> 0 and allows to operate a defrost even during the counting of the time delay dF10 and if the temperature/pressure value lower than the parameter dF19 value for the dF05 time value. If during the time delay dF05 the temperature/pressure becomes higher than the parameters dF1+dF20 (differential) value then the whole procedure is stopped and the time delay dF05 will be reloaded.

25.2 Combined Defrost

This function is enabled only if CF07 = 5 and with Pb4 configured as NTC probe therefore it is used for external temperature on the evaporator coil during the heat pump mode. The detected temperature allows to calculate a better defrost cycle giving the start and the end commands for the cycle itself. Functioning: The Pb3 probe gives the input signal, to start the time delay counting, when its value is lower than dF03 parameter. After the delay dF10 the controller check Pb4 value: if lower than dF11 the defrost procedure starts otherwise the unit still works in Heat Pump. Just after the temperature decreases under dF11 the defrost is enabled. The combined defrost stops just when Pb4 probe value reaches the end defrost temperature in dF12. If the combined defrost is enabled is possible through key, to see the external temperature showed on the upper display for 30 seconds while the lower display shows dEF label.

25.3 Manual Defrost

The unit is working with 1 or 2 compressor running. The start defrost temperature/pressure value must be lower than dF03. If the “combined defrost” is enabled, Pb4 value must be lower than dF11. If the above conditions are satisfied, by pushing SET + o for more than 5s the defrost cycle immediately starts.

27. DATA LOGGER

The data recording is enabled if the log time LG08 > 0. The recordable data can be included enabling the LG01 to

LG07 parameters.

28. BOILER FUNCTION

The electric heater can be activated as heating integration control Ar20=0 or heating control Ar20=1 during the heat pump functioning mode. It is enabled only if:

• Unit configured in Heat Pump mode CF01=3-5.

• Pb4 configured as external air probe CF07=3.

28.1 Heating Integration Control Ar20=0

The Boiler function starts when the Pb4 probe value decreases under Ar21 value. If the water temperature detected by the regulation probe is lower than the ST03 parameter, the electric resistance heater is activated. The on/off algorithm of the electric resistance heater is the same as the compressor control with Heat Pump mode.

If the external air temperature becomes higher than Ar21 + Ar22 (differential), the integration function stops working and the unit restarts (or still work) with Heat Pump mode.

28.2 Heating Control Ar20=1

The Boiler function begins when the Pb4 probe decreases under Ar21 value. When the delay is expired, if the water temperature detected by the regulation probe is lower than the ST03 parameter, the compressors are stopped while the electric resistance heater is activated. The on/off algorithm of the electric resistance heater is the same as the compressor control with Heat Pump mode. If the external air temperature becomes higher than Ar21 + Ar22 (differential), the Boiler functions stops working and the unit restarts with Heat Pump mode, compressors and fans restart working.

29. MAINTENANCE FUNCTION

CO14 for 1st compressor, CO15 for 2nd compressor and CO16 for water pump or supplied air fan (air/air) are the

maximum time running hours to signal a maintenance request, the icon

is blinking. The icon only indicates the need of a check: nothing else happens. It stops blinking just after resetting the hour counter under the function Menu.

30. BLACK OUT

After a black-out:

1. The controller restarts from the pervious status.

2. The defrost cycle is stopped.

3. All the working time delay will be reloaded.

31. INSTALLING AND MOUNTING

31.1 “C” Format (32*74mm)

The instrument shall be mounted on panel, in a 29x71 mm hole, and fixed using the special bracket supplied. To obtain an IP65 protection grade use the front panel rubber gasket (mod. RG-C) as shown in figure 1.
