Ground source heat pumps since 1983
The set value and measured
value for the regulator do not
match.
A maximum limit has been used for the set values.
A spiking over-voltage caused by a lightning strike has
caused a fault in the condenser, causing the temperature to
drop from the actual values.
The regulator must be replaced (not
under warranty).
The regulator motor has been set on manual and the
regulation does not take place.
In the summer, the temperature in the room where the
heat pump is located may rise to up to 30 degrees Celsius.
In these cases, the temperature sensor for the output water
is reading the air temperature instead of the temperature
for the output water.
No action required.
The compressor is on all the
time or for long periods of
time.
A lot of heat is needed, for example the outdoor tempera-
ture is very low or the structure is drying during the first
year’s use of the building.
No action required.
Lack of refrigerant. Can be detected from bubbles in the
liquid container even after some minutes of use.
Contact a refrigeration supplier or
maintenance.
The processor/software on the regulator is faulty.
Turn off the control current switch for
10 seconds and turn it back on. If
turning off the power does not help,
contact maintenance.
If the above instructions do not help, please contact your local Lämpöässä dealer.
PLEASE NOTE! The warranty shall be subject to the existence of an appropriately completed and issued warranty
certificate and a certificate signed by the user stating that the mechanic instructed the user on how to operate the
equipment.
