NOTE
Operation times of the Recirculation pump should be limited to times when comfort is really
needed. If the pump is released for long time, energy consumption may increase a lot due to
heat dissipation into the building and need to re-heat the hot water tank!
NOTE
A schedule (accessible via Main screen) becomes available, after ‘Enable recirculation’ is set to
‘Use’.
NOTE
If you set the start time before the current time, the pump will be activated tomorrow at the set
time.
Example: If you set times as above and it is 19:00 now, the pump will be activated tomorrow at
06:00 for the first time!
