Enter code You have attempted to change the settings in maintenance mode Special settings for maintenance mode are not reguired for normal use Set values for temperatures can be set in normal mode The system does not produce enough heat A sudden drop in outdoor temperature may temporarily cause inadequate heating power in new buildings because moisture contained in the structure takes up a lot of heat when it dries No action reguired During the first year the ground loop may not produce heat at full power because the earth around the ground loop pipes has not yet become more solid No action reguired 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 reguired The compressor is on all the time or for long periods of time A lot of heat is needed for example the outdoor tempera
