By changing the value entered, the respective heating periods will be shortened or
extended.
Increase:
Heating mode will start earlier,
changeover to ECO later.
Decrease:
Heating mode will start later,
changeover to ECO earlier.
• The function is not active in operating mode "Continuously Comfort temperature"
• The display will show ECO
• To give consideration to the building's thermal dynamics, the outside temperature will
be attenuated

Using this limitation, a temperature range for the flow temperature setpoint can be
defined. If the flow temperature setpoint demanded by the heating circuit reaches the
relevant limit and heat request increases or decreases, the flow temperature setpoint
will be maintained at the maximum or minimum limit.

Types of compensation:
When a room temperature sensor is used, there is a choice of 3 different types of
compensation.
Setting
Type of compensation
− − − %
Pure weather compensation *
1...99 %
Weather compensation with room
influence *
100 %
Pure room compensation
* Outside sensor required
The flow temperature is calculated via the heating curve, depending on the composite
outside temperature.
This type of compensation calls for a correct adjustment of the heating curve since in
that case the control gives no consideration to the room temperature .
