S7.5
HEAT PUMP
– OUTDOOR
TEMP. FOR
BIVALENT
OPERATION
MODE
Configures the outdoor temperature
for the bivalent operation mode
of the heat pump and the second
energy source. If the temperature is
lower than the configured one, the
controller switches to the second
energy source immediately after the
heat pump can no longer provide the
demanded water temperature. If the
temperature is higher than the con-
figured one, the controller switches
to the second energy source based
on the temperature deficit or with a
delay. This switchover mode enables
maximum use of energy from the
heat pump or use of energy from the
heat pump even if the latter can-
not provide the necessary energy.
