Wiring diagram:
A. Confirm whether the wiring is correct
1. RC/RH need to be connected together to enable W1 and W2 heating output.
2. C/RC is the 24V AC terminal of the power supply.
3. Y1/Y2 is the terminal for cooling equipment.
4. W1/W2 is the terminal for heating equipment .
5. G is the fan terminal, S is the common terminal line of Y1 and G .
6. AC+/AC- is auxiliary air equipment (such as ventilator, humidifier/dehumidifier).
7.OB is a four-way valve terminal.
8.RT+/RT- is an external sensor.
B. Different device configuration requires mode selection, long press the menu button in
the OFF state to enter the parameter mode setting.
Note: The following parameters are separate control equipment for single cold source and single heat source.
CO1: Single stage cooling (Y1)
CO2: 1 stage cooling(Y1) , 2 stage cooling (Y2)
HE1: Single stage heating (W1)
HE2: 1/2 stage heating (W1/W2)
HC1: cooling (Y1) + heating (W1)
HC2: 1/2 stage cooling (Y1/Y2) + 1/2 stage heating (W1/W2)
Note: The following is the control of compressor or heat pump host + auxiliary heating equipment.
Compressor/heat pump: integrates cold and heat sources to realize cooling and heating.
Auxiliary heating: auxiliary heating equipment, gas heating, electric heating and air conditioning heating.
HP1: 1 pcs heat pump (Y1) + 1 pcs auxiliary heat (W1)
HP2: 2 pcs compressor or 2-speed compressor heat pump (Y1/Y2), +1 pcs auxiliary heat (W1)
HPA: 2 pcs compressor or 2-speed compressor heat pump (Y1/Y2), +2 pcs auxiliary heat (W1/W2)
Factory default HC1: cooling (Y1) + heating (W1)
