  • Page 9: Function

    4.FUNCTION 4-1 System operation control The inputs to the systems come from indoor and outdoor sensors. The outdoor unit is the system MASTER while the indoor one is the SLAVE. Communication between units is made with a 2 poles RS485 bus The indoor 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.
  • Page 10: Cool Mode Operation

    4-2 Cool Mode Operation In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are determined by: 1) the difference between the room air temperature (RAT) and the set point temperature (SPT) 2) the protection level at which the system is operating 3) the thermal load in the room NOTES In addition to the temperature difference of above, the operation of the main components (CM, FMO,...
  • Page 11: Auto Mode Operation (Only Monosplit)

    4-4 Auto Mode Operation (only monosplit) 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 12: Dry Mode Operation

    4-5 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 indoor and outdoor units according to below. ROOM DRY LEVEL TEMP ≥...
  • Page 13: Forced-Made

    4-8 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 indoor unit control board. 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 14: Protection Operation Outdoor Unit

    4-10 Protection operations on outdoor unit 4-10.1 Overheating 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 60 °C 4-10.2 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 16: Night Function

    4-15 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 17: Diagnostic

    4-18 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 indoor unit receive and the 5 leds on the outdoor pcb.
