INFORMATION
When heating of the DHW by the heat pump is too slow, it may affect a comfortable
operation of the space heating/cooling circuit. If so, allow the backup heater to assist
during DHW operation by setting [4-00]=1 or 2.
Maximum capacity
During normal operation the maximum capacity is:
▪ 3 kW for a 230 V, 1N~ unit
▪ 6 kW for a 400 V, 3N~ unit
The maximum capacity of the backup heater can be limited. The set value depends
on the used voltage (see table below) and is then the maximum capacity during
emergency operation.
