Defrost mode is considered:
- If the internal defrost function is active.
In defrost mode:
- Energy acquisition is counted as employed energy heating
- Energy supply is not counted

When, with the heat source currently in operation, the demand for heat cannot be met -
the difference being the release integral set here - another heat source is switched on.

When the valu
e is increased, additional heat sources are switched on at a slower rate.
When the value is decreased, the heat sources are switched off at a faster rate.
When, with the heat source currently in operation, the demand for heat is exceeded by
the reset integral set here, the heat source with the highest priority is shut down.

When the valu
e is increased, the heat sources operate for longer periods of time (in the
case of excess heat).
When the value is decreased, the heat sources are switched off at a faster rate.
Sw
itch-on delay
Correct setting of the s
witch-on delay ensures that the plant maintains stable operating
states. This prevents frequent cycling of the heat sources.
With DHW requests, the delay time is fixed at one minute.
