The unit have a freeze prevention function that uses the
heat pump or backup heater
（
Customized model
）
to
keep the water system safe from freezing in all
conditions. Since a power failure may happen when the
unit is unattended, It's suggested to use anti-freezing
flow switch in the water system. (Refer to 8.5
“
Water
piping”).

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
.
①
Heat pump capacity.
②
Required heating capacity (site dependent).
③
Additional heating capacity provided by backup heater.
The booster heater should be installed below the
temperature probe (T5).
The heat exchanger (coil) should be installed below the
temperature probe.

5 GENERAL INTRODUCTION
These units are used for both heating and cooling applications and domestic hot water tanks.They can be combined with fan
coil units, floor heating applications, low temperature high efficiency radiators, domestic hot water tanks (field supply) and
solar kits (field supply).
A wired controller is supplied with the unit .
If you choose the built-in backup heater unit, the backup heater can increase the heating capacity during cold outdoor
temperatures. The backup heater also serves as a backup in case of malfunctioning and for frozen protection of the outside
water piping during winter time.
