Fig. 5-2 Setting the commissioning parameters
If the storage temperature falls below a certain
minimum value, the safety settings of the ROTEX
HPSU compact prevent the operation of the heat pump
in the case of low external temperatures:
– Extern
al temperature < -2 °C, minimum storage
temperature = 30 °C
– External temperature < 12 °C, minimum storage
temperature = 23 °C.
Without Backup-heater:
The storage tank water must be heated to the minimum
required storage temperature by an external heater.
With Backup Heater (BUxx):
With an outdoor temperature < 12 °C and a storage
ta
nk temperature < 35 °C, the Backup Heater (BUxx) is
switched on automatically on in order to heat up the
storage tank water to at least 35 °C.
Ɣ In order to accelerate the heating process with
the back-up heater, temporarily
– Set parameter [F
unction Heating ] = "1" and
– Set parameter [Power DHW] to the maximum
value of the back-up heater.
– Switch the rotary switch
to operating mode
and set the parameter [1x Hot Water] to "On".
Following successful heating, reset the parame-
ters to "Off".
