5.1.4 Bleeding the hydraulic system
If the storage tank temperature falls below specific
minimum values, the ROTEX HPSU monobloc
compact's safety settings prevent the heat pump from
being operated at low outside temperatures:
– Outside temperature < -2 °C, minimum storage tank
temperature = 30 °C
– Outside temperature < 12 °C, minimum storage tank
temperature = 23 °C.
Without backup heater:
The storage tank water must be heated to the required mini-
mum storage tank temperature with an external heater booster.
With backup heater (BUxx):
At an outside temperature of < 12 °C and a storage tank tem-
perature of < 35 °C, the backup heater (BUxx) is automatically
switched on to heat the storage tank water to at least 35 °C.
To speed up the heating process with backup heater,
temporarily set
– parameter [Function Heating Rod] = "1" and
– parameter [Power DHW] to the maximum value of the
backup heater.
– Set the rotary switch to
the parameter [1x Hot Water] to "On". After heating, set
the parameter to "Off" again.
