● Domestic hot water tank (field supply)
A domestic hot water tank(with or without booster
heater) can be connected to the unit.
The requirement of the tank is different for different unit
and material of heat exchanger.
If the tank volume is greater than 240L, the temperature
probe (T5) should be installed at a position higher than
half of the tank's height.
If the tank volume is less than 240L, the temperature
probe should be installed at a position higher than 2/3 of
the tank's height.
The booster heater should be installed below the
temperature probe.
The heat exchanger (coil) should be installed below the
temperature probe.
The pipe length between the outdoor unit and tank should
be less than 5 meters.
● Room thermostat(field supply)
● Room thermostat can be connected to the unit(room
thermostat should be kept away from heating source
when selecting the installation place).
● Solar kit for domestic hot water tank(field supply) An
optional solar kit can be connected to the unit.
● Remote alarm kit(field supply)
A remote alarm kit can be connected to the unit.
● Operation range
No heat pump operation, backup heater or boiler
only
Water flow temperature drop or rise interval
