(1)
Thermistor for DHW
①
The DHW tank including the thermistor, the DHW electric
heater and the DHW tank inner coil must be designed and
installed in accordance with the local regulation.
②
The position of the thermistor is very important. The
reasonable position will help to ensure the detection accuracy
of the DHW emperature. It is related to the operation of the
heat pump.
(2)
DHW electric heater
①
The electric heater is necessary to heat up the DHW tank in
the following conditions:
Supplement the heat pump to heat up the DHW tank when
ambient temperature.
Heat up the DHW tank when the operating conditions
exceed the limitation, see details in Section “8.1.1
②
The capacity of the DHW electric heater is related to the
storage capacity of the DHW tank, and should be selected
according to the following demand.
heat up the DHW tank, but will consume more power, while
smaller capacity of the electric heater will cost more time to
heat up the DHW tank.
The temperature pressure valve and the temperature
protection device (covered by the control panel ) must be
installed according to local regulation and performed by
