Changeover to electric immersion heater
Select whether in summer operation the DHW should be heated by the elec-
tric immersion heater.
Yes
When the plant switches to summer operation (refer to page 30),
the DHW is heated by the electric immersion heater. This means
that heat generation can be switched off in the summer.
No
DHW is heated by the heat source in the summer also. This means
that heat generation in the summer remains in operation (emer-
gency operation).
If no charging pump is defined, the electric immersion heater is al-
ways released (no charging via the heat source).
