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.
In heating mode, the water flowing temperature (T1)
range in different outdoor temperature (T4) is listed
below:
In cooling mode, the water flowing temperature
(TW_out) range in different outdoor temperature(T4) is
listed below:
Room thermostat(field supplied)
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 supplied)
An optional solar kit can be connected to the unit.

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.

Operation range by heat pump with possible limitation and
protection.
If IBH/AHS setting is valid,only IBH/AHS turns on;
If IBH/AHS setting is invalid,only heat pump turns on,
limitation and protection may occur during heat pump operation.
Heat pump turns off,only IBH/AHS turns on.(IBH can heat the water
temperature up to 65
℃
, AHS can heat the water temperature up to
70
℃
)
Maximum inlet water temperature line for heat pump operation.
