Symptom 3: Pump is making noise (cavitation)

POSSIBLE CAUSES CORRECTIVE ACTION

There is air in the system. Purge air.

Water pressure at pump

inlet is too low.

• Check on the manometer that there is sufficient water pressure.

The water pressure must be > 1 bar (water is cold).

• Check that the manometer is not broken.

• Check that the expansion vessel is not broken.

• Check that the setting of the pre- pressure of the expansion

vessel is correct (refer to "9.3 water piping/Checking the

water volume and expansion vessel pre-pressure").

Symptom 4: The water pressure relief valve opens

POSSIBLE CAUSES CORRECTIVE ACTION

The expansion vessel isbroken. Replace the expansion vessel.

The filling water pressure

in the installation is

higher than 0.3MPa.

Make sure that the filling water pressure in the installation is about

0.15~0.20MPa (refer to "9.3 water piping/Checking the water volume and

expansion vessel pre-pressure").

Symptom 6: Space heating capacity shortage at low outdoor temperatures

Symptom 5: The water pressure relief valve leaks

POSSIBLE CAUSES CORRECTIVE ACTION

Dirt is blocking the water

pressure relief valve

outlet.

Check for correct operation of the pressure relief valve by turning the red

knob on the valve counter clockwise:

• If you do not hear a clacking sound, contact your local dealer.

• In case the water keeps running out of the unit, close both the

water inlet and outlet shut-off valves first and then contact your

local dealer.

POSSIBLE CAUSES CORRECTIVE ACTION

Backup heater operation

is not activated.

Too much heat pump

capacity is used for

heating domestic hot

water (applies only to

installations with a

domestic hot water tank).

Check that the “t_DHWHP_MAX” and “t_DHWHP_RESTRICT” are

configured appropriately:

• Make sure that the “DHW PRIORITY” in the user interface is

disabled.

• Enable the “T4_TBH_ON” in the user interface/FOR SERVICEMAN

to activate the booster heater for domestic water heating.

Check that the "OTHER HEATING SOURCE/ BACKUP HEATER"is

enabled, see "10.7 Field settings" Check whether or not the thermal

protector of the backup heater has been activated (refer to “Controls parts

for backup heater(IBH) ” ). Check if booster heater is running, the backup

heater and booster heater can’t operate simultaneously.

Symptom 7: Heat mode can’t change to DHW mode immediately

POSSIBLE CAUSES CORRECTIVE ACTION

Volume of tank is too

small and the location of

water temperature probe

not high enough

• Set “dT1S5” to 20

°C

, and set “t_DHWHP_RESTRICT” to minimum value.

• Set dT1SH to 2

°C

• Enable TBH, and TBH should be controled by the outdoor unit.

• If AHS(boiler) is available, turn boiler on first, if requirement for

turn heat pump on is fullfilled, the heat pump will turn on.

• If both TBH and AHS are not available, try to change the postion

of T5 probe(refer to 2 General information/Domestic hot water

tank).
