CH system switched off in summer time (Ch pump doesn't run). The boiler
only works in the preparation function of the WAW
- normal operation (parallel operation of the pumps) without favoring the WAW circuit
faster reaching the readiness of the WAW container by restricting the reception of
heat by the heating system. The CH pump runs cyclically. Turning off the WAW pump after
loading the WAW container causes normal operation of the CH pump to come back.
pumps run like in the PRIO mode. Additionally during loading the WAW container
the preset temperature of the boiler is increased to 65 C (the <

Minimal boiler temperature at which the CH pump (P1)
can run.
Minimal boiler temperature at which
the WAW pump (P2) can run.
Break time of the CH pump in a mode of the cyclical run.
After that time the CH pump runs for 45secs.
Temperature hysteresis of turning on/off the pumps.
The temperature difference between turning on and
turning off the pumps. It prevents often switch-overs,
especially if there's another source of heat in the heating
system
Rundown time of the WAW pump. Extending
operation time of the pump after loading the WAW.
It prevents sudden increase of temperature in
the jacket of the boiler after loading , especially
in summer time when the CH pump doesn't run.
Minimum temperature difference between the boiler
and the WAW container needed for operation
of the WAW pump (P2)
