Action / Cause
Check that the heat pump is standing horizontally
Check the connection of the drain tube
Check if there is any dirt in the drain tube
If the compressor recently has been running there is a start delay for 5
minutes
Increase the set point to a higher value
Adjust the mixing valve for hot water
If a lot of hot water has been consumed it can take a long time for the
heat pump to reach the set point
Is the evaporator is blocked by ice or dust? Clean and restart.
If there is a small radiator system connected this might take too much
energy. If so install a thermostat to let hot water production be first
priority.
If there is hot water circulation installed this must be controlled by timer to
make it possible for the heat pump to produce enough hot water.
There might be a leakage in the refrigerant circuit. Contact service.
The air through the evaporator is too low. Clean and reset the alarm.
The temperature in the tank is too high. Change the tank sensor and reset
the alarm
The temperature in to the heat pump is higher than +35 °C
Wait until the temperature rises to more than -10 °C.
If the alarm repeats contact service.
