ROOM value
As mentioned above, you can also adjust heat curve and indoor temperature by changing the ROOM value. If
you use ROOM value to adjust the heat curve, the gradient does not change, i.e. it doesn’t become steeper or
flatter. Instead, the whole curve is moved by 3°C for every degree by which the ROOM value is changed.
The relation supply line temperature to outside air temperature will not be affected. The supply line
temperature will be increased or reduced by the same number of degrees all along the heat curve. See the
following diagram.
Adjustment of the ROOM value should only be used for temporary changes of the indoor temperature. For long
term settings, the CURVE value should be adjusted as this is the most energy and cost efficient way to set the indoor
temperature.
For adjusting the heat curve, please refer to the chapter ”Adjustment of the CURVE value” on page 27.
Factory setting of ROOM value is 20°C.
If you wish to change the ROOM value:
1 Press the ”up” or ”down” button once to open the ROOM value for adjustment.
2 Increase or reduce the preset value using the ”up” or ”down” button so that the desired room temperature is
reached. Wait for 10 seconds or press the left-hand button once to return to the main menu.
