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

Switch-on delay
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 value 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 value 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.
Correct setting of the switch-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.

With automatic source sequence changeover, the heat source loads in a cascade can
be influenced by defining the order of lead and lag heat source.
Fixed order
Setting - - - defines a fixed order.
The heat sources are switched on and off in the order of their LPB device addresses.
