FUNCTIONS 1 System operation control The units receives the user input (fan speed, flap position etc) through remote controller which sends signal every time a button is pressed and in any case, automatically, every 5 minutes. During operation compressor speed can be subjected to change due to thermal load variations or protection activations but in any case: •... -
Page 10: Auto Mode Operation
4 Auto Mode Operation In Auto Mode, the unit switches automatically between the Auto Cooling and Auto Heating in order to maintain the room temperature (RAT) at the prescribed set point (SPT). The switching between the two modes is according to the above graph and following table COOLING --->... -
Page 11: Dry Mode Operation
5 Dry Mode Operation Dry operation remove moisture from indoor air running, in cooling mode, at a low level without reducing the ambient temperature. This is done cycling ON and OFF the unit according to table below. ROOM DRY LEVEL TEMP ≥... -
Page 12: Forced Mode
8 Forced Mode In this mode the system operates (COOLING or HEATING mode – fixed settings) or is switched off by means of the MODE button on the pcb receiver. The operation modes can be selected pressing the button in a cyclic way (OFF COOL HEAT OFF…). The settings are: COOLING mode SET POINT temperature = 25°C FAN SPEED = HIGH... - Page 13 9.4 Overheat outdoor exchanger During cooling operation as soon as the outdoor coil temperature (OCT) increases, compressor speed is reduced in order to avoid heat exchanger overheating. System stops compressor operation when OCT reaches 65 °C 9.5 Compressor discharge temperature During operation, as soon as the discharge temperature increases, (CDT) compressor speed is reduced in order to avoid overheating of the motor.

Page 15: Night Function
14 NIGHT Function When this setting is active indoor fan speed is automatically reduced in order to allow low noise operation.Temperature control acts in the same way as NORMAL MODE but after 60 minutes of operation the air conditioner modifies automatically the set-point temperature according to the following: •COOLING/DRY: +1°C •HEATING: - 2°C... -
Page 16: Diagnostic
17 Diagnostic With this feature is possible to have a visual signal that a trouble is occurring. This mode is always active and the signalling is made through the display board LEDS . In case of no troubles the LEDS status follows its normal function. The detected troubles are showed to the user/technician using the 3 leds of the receiver For each fault there are different effects upon the operation of the A/C: NOTES... -
Page 17: Address
18 Address Changing the Address of the Air Conditioner In case of more than one air conditioner operating in the same room, it may be necessary to assign an address to each unit in order to avoid operation conflicts. Address is set acting on jumpers located on the unit PCB and on dip-switches of the remote controller. -

19 Manual Unit Control and LED indicators The push button switch and the LED indicators on display panel let the user to control the unit operation without a R/C (Remote Controller). Their operations are provided below. Push Button Switch : Use to cycle the operation mode of the A/C unit among COOL, HEAT and OFF modes, without using the R/C. -
Page 19: Drain Pump
20 Drain pump Pump operates when the unit is running in COOLING and DRY modes. The level detection is done through a float switch connected at the input FS (closed under normal condition, and opened when water overflows). System operation is according to the following chart: 21 Safety thermostat The unit is equipped with a double safety system to prevent overtemperature of the electrical heater... -
