0020287900_01 sensoCOMFORT Operating and installation instructions
Cooling starts once the outdoor temperature (24-hour average) exceeds the set temperature.
Factory setting: 15 °C
The system control switches the Cooling function on and guides the heat from the living
room back to the earth via the heat pump. Prerequisite:
The Automatic cooling: function has been activated.
The Absence function is active.
Factory setting: No
→ triVAl
The heat generator is selected based on the set tariffs in relation to the
heat demand.
→ Bival. point
The heat generator is selected based on the outdoor temperature (
Heating bivalence point: °C and Alternative point:).
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.
Prerequisite: Bival. point is selected in the Hybrid manager: function.
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.
Factory setting: -7 °C
If the outdoor temperature falls below the set value, the system control switches the heat
pump off and the back-up boiler meets the heat demand in heating mode.
Prerequisite: Bival. point is selected in the Hybrid manager: function.
Factory setting: Off
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.
The end user can use the Mode: Temporary back-up boiler mode function to enable the
back-up boiler and therefore deactivate the target flow temperature that is set here.
Factory setting: 25 °C
Select a type for the heat generator that is also installed. An incorrect selection may lead to
increased costs.
Prerequisite: triVAl is selected in the Hybrid manager: function.
Factory setting: Condensing
Define what you want to deactivate when the signal is sent by the energy supply company or
an external control. The selection remains deactivated until the signal is cancelled.
The heat generator ignores the deactivation signal as soon as the frost protection function is
active.
Settings for the deactivation signal from the energy supply company:
HP off
Back-up heat. off
HP + BUH 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 control:
Heating off
Cooling off
Heat. + cool. off
For the settings Heating off, Cooling off and Heat. + cool. off, the ESCO contact on the
heat pump means the following:
closed = enabled
open = locked
Factory setting: HP + BUH off
→ DHW + heat.
The back-up boiler does not support the heat pump.
The back-up boiler is activated for the anti-legionella function, frost pro-
tection or de-icing.
