Domestic hot water preparation

3.2.2

Room temperature control optimisation

Building too hot
Building is not heating up
Reference room is warm, 
but individual rooms (e.g. bathroom) too cold
Reference room is not 
reaching the room set temperature, 
but individual rooms (e.g. bathroom) are hot

3.3 Fixed-setpoint control

In special cases (e.g. heating a buffer to a constant temperature),
it is possible to set a characteristic curve which is independent of
the external temperature. Make selections in the menu "Settings
– Heating circuit 1/2/3 – Control by – Fixed-setpoint". The
desired return set temperature can be set in the following menu
item "Fixed-setpoint Control – Return set temp.".
4 Domestic hot water preparation
Domestic hot water cylinders with a sufficient heat exchange
surface should be used for domestic hot water preparation.
These must be capable of permanently transferring the
maximum heat output of the heat pump.
Control is carried out using a sensor (R3) installed in the
domestic hot water cylinder. The sensor is connected to the heat
pump manager.
The temperatures attainable in heat-pump-only operation are
below the maximum flow temperature of the heat pump.

4.1 Basic heating

A request for domestic hot water is recognised if the current
Domestic hot water temperature < Domestic hot water set
temperature - is domestic hot water hysteresis.
A request for domestic hot water is ended if either the domestic
hot water set temperature or the maximum (Chapt. 4.1.2 on p.
20) HP temperature, as depending on the heat source, is
reached.

Hotter (
For higher domestic hot water temperatures, the heat pump
manager offers optional control of a flange heater.
Regulation can also be carried out using a thermostat. With this
application, selective reheating using a flange heater is not
possible.
NOTE
The additional setting options for heat pumps with an additional heat
exchanger installed in the hot gas are described in Chapter Chapt. 8 on
p. 28.
NOTE
The domestic hot water preparation can be interrupted by defrosting or
by the high pressure safety program.

Raise minimum return temperature. 
This can lead to the room set temperature in
