Substitute
The electric immersion heater ensures DHW charging should the heat pump go to
lockout, should it be off, or should DHW charging be aborted by the heat pump.
El imm heater
optg mode
If the electric i
mmersion heater must ensure DHW charging because the heat pump
was not able to complete the charging process, the controller saves the DHW
temperature at which the electric immersion heater took over on operating line "Curr
DHW charg temp HP"(7093).
Also, at the changeover point, the switch-on temperature is readjusted. If the DHW
temperature increases due to the electric immersion heater or some other heat source
(e.g. solar), the switch-on point also increases according to the slave pointer principle.
The switch-on point increases to a maximum of current DHW setpoint minus switching
differential. If the DHW temperature falls below the switch-on point, the heat pump will
be put into operation.
Summer
When all heating circuits have switched to summer operation, the electric immersion
heater ensures DHW charging from the next day. This means that the heat pump
remains deactivated during summer operation.
DHW heating via the heat pump is resumed only when at least one of the heating
circuits has switched to heating mode.
In heating mode, the electric immersion heater is operated as described above under
"Substitute".
Always
DHW charging is always provided by the electric immersion heater.
The DHW operating mode button also acts on the electric immersion heater. For
the DHW to be heated, the DHW operating mode button must be pressed.
