Adjust the heating system during the winter to obtain the greatest possible output.

Tuning must be carried out over a few days as the inertia in the heating system causes the indoor tempera-
ture to change slowly.
1. Choose one of the rooms in the house as a reference room for the indoor temperature, use the room where the highest tempera-
ture is wanted, 20-21°C.
2. Place a thermometer in the room.
3. Open all radiator valves in the heating system fully.
4. Set the room temperature on the heat pump to 20°C.
5. Note the temperature in the reference room at different points in time over a 24 hour period.
6. Adjust the room temperature so that the reference room reaches your required indoor temperature of 20-21°C. Remember that the
other rooms will have different temperatures during tuning, but these are adjusted later.
7. When the reference room has an even temperature of 20 - 21°C over a 24 hour period, you can adjust the radiator valves in the
other rooms so that their indoor temperatures are the same temperature or lower than the reference room.
9.8 Customer information
After installation and test operation, the customer must be informed about their new heat pump installation. It is important that the
customer understands the behaviour of the heat pump and the result of any changes made to the default settings in the control system.
See the checklist and Installation Protocol in the user guide regarding the information that the installer must give the customer.
N
The serial number must always be given for warranty matters. The serial number is found on the exterior of
the heat pump cabinet. The serial number must be noted in the Installation Protocol.
