The antilegionella cycle:
•
Is enabled in the time bands set by scheduler
•
is always the priority on the ambient
thermoregulation
•
SetPointaccumulo uses only the electric
resistances
•
SetPointaccumulo can use the heat pump instead
of the resistances.
STORAGE
phase:
•
It is disabled in the time bands set by the scheduler
•
During this phase, the heat pump produces DHW if
the storage temperature drops down the DHW band
set point: medium storage temperature
MAINTENANCE
phase:
•
always active but not during the storage phase
•
this phase, unlike the previous, agrees that the
medium temperature drops furtherly down before the
heat pump is activated : medium storage
