Page 15: Principle Of Functioning
6 Principle of functioning Heating mode When the unit is in heating mode, the system will regulate the heating capacity delivered to the room to increase the room air temperature (RAT) to the set point (SPT) and to balance the thermal load of the room to keep the set point temperature. - Page 16 Dehumidification (dry) mode When the unit is in dry mode, the system will operate according to the following table: DRY LEVEL DESCRIPTION ≥ SPT + 2°C Unit operates normally in cooling mode. Unit operates with a fixed cooling demand. < SPT + 2°C Indoor fan switches between very low speed and ≥...

Page 17: Components Operation
7 Components operation Compressor The compressor runs if the following conditions are met: At least 3 minutes have passed since the power supply was switched on At least 3 minutes have passed since the compressor was stopped At least 6 minutes have passed since the previous compressor start There is no active alarm on the outdoor and indoor units There is no active protection There is a thermal load demand in the room... - Page 18 Crankcase heater Crankcase heater around the compressor is used to prevent refrigerant migration and mixing with crankcase oil when the unit is off, and to prevent condensation of refrigerant in the crankcase of the compressor. The crankcase heater keeps refrigerant at a temperature higher than the coldest part of the system.

Page 19: Defrost
8 Defrost A defrost starts if one of these conditions is satisfied (see graph below): - OCT falls below L1 line and compressor is running for at least 35 minutes without defrost - OCT falls below L2 line and compressor is running for at least 60 minutes without defrost A defrost ends if one of these conditions is satisfied: - OCT rise above 14°C and defrost has been active for at least 2 minutes - defrost has been active for 12 minutes... - Page 20 Before reversing the cycle at the beginning and at the end of the defrost, the compressor ramps down to decrease the pressure inside the circuit: When defrost is active: 4-way valve is deactivated Compressor runs at a fixed speed (if no protection is active) EEV is open at a fixed value Fan is off When defrost ends:...

Page 21: Protections
9 Protections The unit is equipped with an automatic system of protections. These protections, if active, will limit the speed of the compressor in order to run the system in a safe operating area. Protections, when active, reduce the speed of the compressor linearly down to its minimum speed. If the level of protection is too high, compressor is stopped until no protection will be active. - Page 22 Over power consumption from the power supply This protection checks the power consumption of the outdoor unit (but not of the indoor unit) to avoid an excessive power consumption than can damage the pcb and the unit. This protection is always active and limits the compressor speed to keep the outdoor unit power consumption below 1800W.
