Operation

2.1 General
DANGER!
If electrical components come into contact with water,
this can cause an electric shock as well as cause
potentially fatal injuries and burns.
Protect the displays and keys on the control
systems from the effects of moisture.
To clean the display, use a dry cotton cloth.
Using aggressive cleaning agents and other
liquids can cause damage to equipment or lead
to an electric shock.
Maximum energy utilisation
The most effective energy utilisation is achieved by the
unit at the lowest possible return flow and hot water
temperatures.
At temperatures in excess of 50 °C, the effectiveness
(COP) of the HPSU compact will be made worse by
the heatingsupport provided by the optional heater
(backup heater).
The safety settings of the HPSU compact hinder the
operation of the heat pump if
– the outdoor temperature is < 12 °C and simultane-
ously
– the storage tank temperature is < 30 °C.
Without backup heater:
At an outdoor temperature < 12 °C, the storage tank
water needs to be heated up by an external heater to
> 30 °C.
With backup heater (BUH):
At an outdoor temperature < 12 °C, the backup heater
(BUH) switches on automatically to heat the water in
the storage tank to > 30 °C.
In order to accelerate the heating up process with
BUH, temporarily set the
– Parameter [T-DHW 1 des] > 55 °C,
– Parameter [Function Heating Rod] = "1" and
– Parameter [BOH power] = 9000 W.
