Air-to-water Heat Pump Split Versati

SPLIT TYPE

Emergency mode

: this mode is only available for heating and water heating. When the outdoor unit stops due 

to malfunction, enter the corresponding emergency mode; as to heating mode, after entering the emergency mode, 
heating can only be realized through e-heater of the indoor unit. When the setting outflow temperature or indoor 
temperature is reached, the e-heater of indoor unit will stop running; as to water heating mode, the e-heater of 

indoor unit stops while the e-heater of water tank runs. When the setting temperature or water tank is reached, the 
e-heater will stop running.

Quick water heating

: in quick water heating mode, the unit runs according to the water heating control of heat 

pump and the e-heater of water tank runs at the same time.

Forced operation mode

: this mode is only used for refrigerant recovery and debugging for the unit.

Holiday mode

: this mode is only available for heating mode. This mode is set to keep indoor temperature or 

leaving water temperature in a certain range, so as to prevent water system of the unit from freezing or protect 
certain indoor articles from freezing damage. When the outdoor unit stops due to malfunction, the two e-heaters of 
the unit will run.

Disinfection mode

: in this mode, the water heating system can be disinfected. When starting up the disinfection 

function and setting corresponding time to meet the requirement of disinfection mode, the function will start. After 
the setting temperature is reached, this mode will terminate.

Weather-dependent operation

: this mode is only available for space heating or space cooling. In Weather-

dependent mode, the setting value (remote room air temperature or leaving water temperature) is detected and 
controlled automatically when the outdoor air temperature is changed.

Quiet mode

: silent mode is available in cooling, heating and water heating mode. In silent mode, the outdoor 

unit will reduce the running noise via automatic control.

Floor commissioning

: this function is intended to preheat the floor periodically for the initial use.

Air removal of the water system

: this function is intended to replenish water and remove air in the water 

system to make the equipment run at the stabilized water pressure.

Solar water heater

: when the condition for starting the solar water heater is satisfied, the solar heater will start 

to heat the circulation water. Then the heated water will go to the water tank and exchange heat with water in it. At 
any condition, the solar water heater will be given priority for startup so as for energy conservation.

Backup heat source

: when the outdoor temperature is lower than the set point for starting the backup heat 

source and the unit is under the error condition and the compressor has stopped for three minutes, then the backup 
heat source will start to supply heat or hot water to the room.
