Heat gains

•
To save energy, heat gains are taken into consideration
This setting takes into account potential heat gains from machines, pieces of
equipment, or other constant heat sources, that might adversely affect accurate control.
The value will change when the heating curve adaption is activated.
1. Press the line selection buttons to select line 35OEM.
2. Press the + / - buttons to set the effect of heat gains.
Setting range
-2...+4
The setting compensates the sum of all constant heat gains as follows:
Increase: For more compensation
In the case of significant heat sources
Decrease: For less compensation
In the case of less significant heat sources
The setting in °C corresponds to the temperature differential that would result if the
room was solely heated by the heat gains.
