The collector pump is periodically switched on for the running time set here.
The time that the collector start function starts or stops is set here.
As soon as there is a temperature increase on the collector sensor, the collector
pump switches on. The higher the value here is set, the larger the temperature
increase must be.
In order to prevent freezing of the collector, the collector pump will be activated
in case of frost danger.
In case of overheating danger, charging of the storage will be continued to re-
move heat. When reaching the storage safety temperature charging of the stor-
age will be interrupted.
Pump protecting function, to prevent overheating of the collector pump in case of
evaporating danger of the heat carrying medium due to high collector tempera-
ture.
Information of the antifreeze used.
Input of antifreeze concentration for usage measurement of solar energy.
Input of the flow of the installed pump for calculation of the brought in volume
for usage measurement.
Defines the flow per pulse for the Hx inlet. The Hx inlet must be configured to
pulse count for this.

8.4.14 Solid fuel boiler

If the solid fuel boilers are activated, other heat generators, e.g. oil./gas boilers,
are blocked, as soon as an increase in the boiler temperature is discovered that
points to the exceeding of the comparative temperature (prog. no. 4133).
The boiler pump is only put into operation if the boiler temperature has reached
the minimum setpoint set here in addition to the necessary temperature differ-
ence.
