2 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 and solar kits, which
are all field supplied.
A wired controller is supplied with the unit .
The backup heater(Optional) can increase the heating capacity at pretty low outdoor temperature. And it also serves as
backup service in case of malfunction of heat pump or avoiding freezing of outdoor water pipes.
Maximum length of communication wirings between the unit and the controller is 50m.
Power cords and communication wiring must be laid out separately, they can not be placed in the same conduit.
Otherwise, it may lead to electromagnetic interference. Power cords and communication wirings should not come
in contact with the refrigerant pipe so as to prevent the high temperature pipe from damaging wirings.
Communication wirings must use shielded lines.Including indoor unit to outdoor unit PQE line ,indoor unit to controller
HA and HB line.

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