>> Hot water production
B Select Yes if heat pump 2 should take part in the hot
water production. Heat pump 1 must make hot water.
Heat pump 2 can work with another hot water heater. In
this case, E42.T3 is used for start and stop. This sensor
must then be connected.
At Yes a further external 3-way valve is required.
B Set values for heat pump 2 for Economy and Comfort.
Factory settings are 10K lower then for heat pump 1.
> Block heating during hot water demand
B Yes should always be used.
> Maximum temperature difference circuit 1
B Indicate how many degrees lower than the set point
value for the flow temperature - half the hysteresis
may become before the heating priority kicks in.
Heat pump 2 stops producing hot water and switches
over to heating. The set point value for the flow
temperature is reduced with the set temperature
difference. This setting has no relevance when only
heat pump 1 produces hot water.
> Hot water circulation (accessory)
A special circulation pump for hot water, E41.G6, can be
installed. It is subject to time control, i.e., it can be
activated during parts of the day. Due to the circulation,
the hot water reaches the tapping place faster.
>> Hot water circulation pump active
B Select Yes if a circulation pump is installed.
Then time settings can be done.
Yes sets the hot water mode to Comfort
automatically and the menu Hot water mode is not
shown.
