Heat curve
The heat pump operates by holding flow temperature
E11.T1 in relation to outdoor temperature E10.T2
according to the set heat curve.
The appearance of the heat curve depends on settings
for the minimum outdoor temperature (
DOT
, factory
setting -35 °C), lowest flow set point (factory setting
20 °C) and highest flow set point (60 °C). This heat
curve is appropriate for radiator systems.

Radiator system
When the factory setting is changed, the heat curve is
redrawn automatically. Any adjustments to the curve
disappear.
The curve is set in E21 and applies to all heat pumps.
Example of a floor heating curve:

The factory settings refer to heating systems with normal flow. For low flow systems Min 3 K, Max 16
K is recommended. For high flow systems (floor heating) Min 1 K, Max 4 K is recommended.

Set the minimum and maximum hysteresis and time factor for hysteresis reduction after start/stop.
Current hysteresis, as well as actual value and set point for E11.T1 are shown.

The function means that the set point for the flow temperature is successively adjusted with respect
to the set point at the current outdoor temperature. This reduces the effect of brief fluctuations in
outdoor temperature.
B
Set the time for the flow temperature set point to reach the current curve value.
