5.55 Heat gains (Tf)
•
To save energy, heat gains are taken into consideration
This setting takes into account potential heat gains from machines, pieces of equip-
ment, or other constant heat sources, that might adversely affect accurate control. The
value will change when the heating curve adaption is activated.

Factory setting
-2...+4 K

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 K corresponds to the temperature differential that would result if the room
was solely heated by the heat gains.
5.56 Adaption sensitivity 1 (ZAF2)
•
Different heating curve adaptions as a function of the outside temperature
Adaption sensitivity 1 serves for calculating the heating curve adaption in the
temperature range
between
4...12 °C. Also refer to section “Adaption of heating curve”,
operating line 726.

1...15 –

The level of adaption sensitivity is automatically adapted by the controller and, there-
fore, need not be manually adjusted.
The heating curve in the temperature range between 4 and 12 °C will be differently
adapted, depending on the level of adaption sensitivity 1.
Increase: More
adaption
Decrease: Less
adaption
Each time a significant adaption of the heating curve
between
4 and 12 °C (ZAF1) has
taken place, adaption sensitivity 1 will automatically be reduced by one step. This
means that the extent of adaption and thus the readjustment of the slope and the heat-
ing curve’s parallel displacement will gradually be reduced .
When readjusting the slope of the heating curve (operating line 30), the adaption sensi-
tivity will automatically be reset to the factory-set value.
Refer to the next section "Adaption sensitivity 2“.
For more detailed information about the effects, refer to operating line “Adaption of the
heating curve” (operating line 726).
