2. Operating Principle of the Unit
DC Inverter Air to Water Heat Pump is composed of outdoor unit, indoor unit and internal-fan coil water tank.
Operation functions:
(1) Cooling;
(2) Heating;
(3) Water heating;
(4) Cooling +water heating;
(5) Heating+ water heating;
(6) Emergency mode;
(7) Quick water heating;
(8) Holiday mode;
(9) Forced Operation Mode;
(10) Silent mode;
(11) Disinfection mode;
(12) Weather-dependent Operation;
(13) Floor debugging;
(14) Air removal of the water system;
(15) Solar water heater;
(16) Backup heat source
Cooling:
in cooling mode, the refrigerant is condensed in the outdoor unit and evaporated in the indoor unit. Via
the heat exchange with water in the indoor unit, the temperature of water decreases and it releases heat while the
refrigerant absorbs heat and evaporates. With the help of wired controller, the outow temperature can meet the
user’s requirement. Through the control of valve, the low-temperature water in the system is connected with indoor
fan coil and underground pipe, and exchanges heat with the indoor air so that the indoor temperature decreases to
the required range.
Heating:
in heating mode, the refrigerant evaporates in the outdoor unit and is condensed in the indoor unit.
Via the heat exchange with water in the indoor unit, the water absorbs heat and its temperature increases while the
refrigerant releases heat and is condensed. With the help of wired controller, the outow temperature can meet the
user’s requirement. Through the control of valve, the high-temperature water in the system is connected with indoor
fan coil and underground pipe, and exchanges heat with the indoor air so that the indoor temperature increases to
the required range.
Water heating
: in water heating mode: the refrigerant evaporates in the outdoor unit and is condensed in
the indoor unit. Via the heat exchange with water in the indoor unit, the water absorbs heat and its temperature
increase while the refrigerant releases heat and is condensed. With the help of wired controller, the outflow
temperature can meet the user’s requirement. Through the control of valve, the high-temperature water in the
system is connected with the coil pipe of bearing water tank, and exchanges heat with the water in the water tank
so that the temperature of water tank increases to the required range.
Cooling + water heating
: when cooling mode exists together with the water heating mode, the user can set the
priority of these two modes based on the needs. The default priority is heat pump. That is under the default setting,
if cooling mode exists together with the water heating mode, the heat pump gives priority to cooling. In that case,
water heating can only realized with e-heater of the water tank. Inversely, the heat pump gives priority to water
heating and switches to cooling after nishing water heating.
Heating+ water heating
: when heating mode exists together with the water heating mode, the user can set the
priority of these two modes based on the needs. The default priority is heat pump. That is under the default setting,
if heating mode exists together with the water heating mode, the heat pump gives priority to heating. In that case,
water heating can only realized with e-heater of the water tank. Inversely, the heat pump gives priority to water
heating and switches to heating after nishing water heating.
Air-to-water Heat Pump Split Versati

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 outow 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 oor 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 satised, 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.
