9.3 Control of the 2nd Heat Generator

9.3.1

Control of Immersion Heaters

Supplementary electric heating systems are used in mono
energy systems. These are switched on or off depending on the
heat consumption if the "Mono energy" operating mode is
9.3.2

Constantly Regulated Boiler (Mixer Regulation)

When implementing this type of boiler, the boiler water is always
heated to a set temperature (e.g. 70 °C) when the command is
issued accordingly by the heat pump controller. This temperature
must be set so high that domestic hot water preparation can also
be carried out using the boiler according to need. Regulation of
the mixer is undertaken by the heat pump controller. If required,
9.3.3

Variably-Regulated (Gliding) Boiler (Burner Regulation)

In contrast to the constantly-regulated boilers, variably-regulated
boilers supply hot water at a temperature which is directly based
on the respective external temperature. The three-way reversing
valve has no regulatory function. However, it has the task of
directing the hot water flow past or through the boiler, depending
on the operating mode.
In the case of heat pump only operation, the heating water is
directed past the boiler to avoid losses caused by heat

9.4 Power Regulation

The heat pump controller can define a maximum of 2 power
stages, L1 and L3, which it switches depending on the heat
consumption. Rising heat consumption causes the next highest
power stage to be switched, falling heat consumption the next
lowest.
L1: P1: Heat pump operates with one compressor

Heat Pumps with One Compressor

Criteria for a switchboard:
From L1 to L3 if the heating controller demands "more heat"
for more than 60 minutes and the external temperature
simultaneously remains under the limit temperature of the
2nd heat generator for more than 60 minutes.

it calls for the boiler and adds more hot water until the desired set

boiler is called via the 2nd heat generator output of the heat
pump controller and the operating mode of the 2nd heat
generator is coded as being "constant".
dissipation of the boiler. If the system is equipped with
atmospherically controlled burner regulation, the voltage supply
for burner regulation should be disconnected in the case of heat
pump only operation. The boiler is controlled via the 2nd heat
generator output of the heat pump controller, and the operating
mode of the 2nd heat generator is coded as being "variable". The
characteristic curve of the burner regulation is set according to
the heat pump controller.
