The outgoing water temperature is too high
If the outgoing water temperature in heating mode is higher than 57 °C, the compressor will switch
off.
Check:
•
temperature sensor
•
water temperature
•
water flow rate
Defrost error
If the unit fails to complete the evaporator defrost 3 times in a row, the compressor will turn off.
Check:
•
water temperature
Water temperature too low in heating or DHW mode
If the water temperature is lower than 15 °C, the compressor will switch off. The compressor switches
on when the flow temperature exceeds 17 °C. This is a protection that prevents damage to the
compressor.
Low flow rate
If a flow error occurs 3 times in a row, the compressor will switch off.
Check:
•
system pressure / air presence
•
clogged filter
•
status of the circulation pump
•
opening / throughput of water circuit fittings
6. RELATED DOCUMENTATION
-
Instructions for installation and operation of the heating controller according to the selected
application. Wiring methods are given in chapter 2.
-
Installation and operating instructions for the components belonging to the appliance (hot
water storage tanks, thermal stores, valves and actuators, etc.).
-
Heat pump commissioning report - issued by an authorised person authorised by the service
organisation.
7. DECOMMISSIONING
In cases where water in the unit may freeze (e.g. when the unit is out of service), drain all water from
the heat pump water circuit and piping. After draining the water, also switch off the electrical supply
to the equipment with the circuit breaker.
8. RECYCLING / DISPOSAL
Components made of steel, copper and copper alloys shall be handed over to a sorted metal waste
collection site. Electronic components such as electronic boards must be handed over to a collection
point designated for electrical waste.
Warning: Current regulations do not allow refrigerant to escape into the environment. All
refrigerant must be professionally extracted by a certified person and handed over to the
appropriate collection sites.
