Control signal boiler pump
If the boiler sets the forced signal to zero, the consumers and heat exchanges that
had responded to the forced signal act as follows:
They close the mixing valves/2-port valves
Their pumps continue to run for the set overrun time and then stop
D.h.w. discharging protection takes priority over protection against boiler
overtemperatures.

For pump M1, it can be selected via operating line 99 whether or not it shall run
during protective boiler startup:
Circulating pump without deactivation (setting 0):
The circulating pump runs when one of the consumers requests the boiler to
supply heat and when burner stage 1 is on, hence, during protective boiler
startup also
Circulating pump with deactivation (setting 1):
The circulating pump runs when one of the consumers requests the boiler to
supply heat. During protective boiler startup, the pump is deactivated
