1. Open the HEAT CURVE menu in the INFORMA-
TION menu.
2. Select the parameter required using the + or –
button.
3. Open the parameter by pressing the right but-
ton once.
4. Increase or reduce the value with the + or - but-
ton.
5. Press the left button three times.
The heat curve and therefore the indoor temperature can be affected by changing the ROOM value. If the
ROOM value is used to affect the system’s heat curve, the heat curve does not become steeper or flatter, as it
does when the CURVE value changes. Instead the entire heat curve is moved by 3°C for every degree change of
the ROOM value.

For a temporary increase or decrease of the indoor temperature, adjust the
ROOM value.
Change the ROOM value as follows:
1. Press either the + or - button once to open and change the ROOM value.
2. Increase or decrease the ROOM value using the + or - buttons to change the indoor temperature.
3. Wait ten seconds or press the left button once to exit the menu.

The setpoint value for the supply line and the max value of the return line
are shown in brackets. The max value indicates the temperature at which
the compressor is stopped. No values can be changed in this menu.
The present temperatures in the system are shown here. Temperatures are
recorded and stored for 100 minutes so that they may be displayed graph-
ically
If ROOM shows 20°C the heat curve is unaffected. If ROOM shows a higher
or lower value, this indicates that the heat curve has been adjusted up or
down.
