If the outdoor temperature falls below the set value, the system
control enables the back-up boiler to operate in parallel with the
heat pump in heating mode.
-30 to +20 °C, increment 1, factory setting: 0 °C
If the outdoor temperature falls below the set value, the system
control activates the back-up boiler in parallel with the heat pump.
-20 to +50 °C, increment 1, factory setting: -7 °C
Set a low target flow temperature. If the heat pump fails, the back-
up boiler fulfils the heat demand, which leads to higher heating
costs. The end user should recognise that heat loss means that
there is a problem with the heat pump.
From 20 to 80 °C, increment 1, factory setting: 25 °C
Off: The back-up boiler does not support the heat pump.
For heating: The back-up boiler supports the heat pump during
heating. The back-up boiler is activated for the anti-legionella func-
tion.
For domestic hot water: The back-up boiler supports the heat
pump during domestic hot water generation. The back-up boiler is
activated for frost protection or de-icing.
For heating and domestic hot water: The back-up boiler supports
the heat pump during domestic hot water generation and heating.
Factory setting: Not set
Define what you want to deactivate when the signal is sent by the
energy supply company or an external control. The selection re-
mains deactivated until the signal is cancelled. The heat generator
ignores the deactivation signal as soon as the frost protection func-
tion is active.
Settings for the deactivation signal from the energy supply com-
pany:
Heat pump off, Back-up heater off, Heat pump and back-up heater
off
For the settings HP off, Back-up heat. off and HP + BUH off, the
ESCO contact on the heat pump means the following
–
closed = locked
–
open = enabled
Settings for the deactivation signal from an installed external con-
trol:
Heating off, Cooling off, Heating and cooling off
For the settings Heating off, Cooling off and Heat. + cool. off, the
ESCO contact on the heat pump means the following
