N O T E
(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 accord-
ance 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 T he 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 the
heating capacity of the heat pump is insufficient in low ambient
temperature.
• Heat up the DHW tank when the operating conditions exceed the
limitation, see details in Section 1 "GENERAL INFORMATION".
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.
• Larger capacity of the DHW electric heater is beneficial to 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 qualified professionals referring to
Section "8.4.2 Safety device".
