It is possible to balance the circulation again anytime.
During the cascade operation mode, the circulation pump is connected to the master.
During the adjusting process, only the station of the master controller is connected
(cascade valve master = on).
The cascade valves of the slaves are closed.
During a withdrawal, the circulation can remain active.
An additional external circulation sensor can be defined. This can be useful to minimise the
runtime of the secondary pump and to spot pipes with a bad circulation.
The circulation function provides 3 operating modes, which can be combined as well.
- Circulation: Temperature controlled
- Circulation: Time controlled
- Circulation: Demand
- Combination of operating modes
Depending on the activated mode, additional settings are required.
