ROTEX HPSU low temperature Bi‑bloc
4P384979-1B – 2016.02
INFORMATION
▪ During heating operation of the heat pump, the
heat pump operates to achieve the desired
temperature set via the user interface. When weather-
dependent operation is active, the water temperature is
determined automatically depending on the outdoor
temperature.
▪ During heating operation of the auxiliary boiler, the
auxiliary boiler operates to achieve the desired water
temperature set via the auxiliary boiler controller.
Setup
▪ Integrate the auxiliary boiler as follows:

NOTICE
▪ Make sure the auxiliary boiler and its integration in the
system complies with applicable legislation.
▪ ROTEX is NOT responsible for incorrect or unsafe
situations in the auxiliary boiler system.
▪ Make sure the return water to the heat pump does NOT exceed
55°C. To do so:
▪ Set the desired water temperature via the auxiliary boiler
controller to maximum 55°C.
▪ Install an aquastat valve in the return water flow of the
heatpump.
▪ Set the aquastat valve to close above 55°C and to open below
55°C.
▪ Install non-return valves.
▪ Make sure to only have one expansion vessel in the water circuit.
An expansion vessel is already premounted in the indoor unit.
▪ Install the digital I/O PCB (option EKRP1HB).
▪ Connect X1 and X2 (changeover to external heat source) on the
PCB to the auxiliary boiler thermostat.
▪ To setup the heat emitters, see "5.2Setting up the space heating/
cooling system"on page11.
Configuration
Via the user interface (quick wizard):
▪ Set the use of a bivalent system as external heat source.
▪ Set the bivalent temperature and hysteresis.
NOTICE
▪ Make sure the bivalent hysteresis has enough
differential to prevent frequent changeover between
indoor unit and auxiliary boiler.
▪ Because the outdoor temperature is measured by the
outdoor unit air thermistor, install the outdoor unit in the
shadow so that it is NOT influenced or turned ON/OFF
by direct sunlight.
▪ Frequent changeover may cause corrosion of the
auxiliary boiler. Contact the manufacturer of the
auxiliary boiler for more information.
Changeover to external heat source decided by an auxiliary
contact
▪ Only possible in external room thermostat control AND one
leaving water temperature zone (see "5.2 Setting up the space
heating/cooling system"on page11).
▪ The auxiliary contact can be:
▪ An outdoor temperature thermostat
▪ An electricity tariff contact
▪ A manually operated contact
▪ …
▪ Setup: Connect the following field wiring:
