0020288151_00 sensoCOMFORT Operating and installation instructions
List of eBUS components and their software versions
Automatic fine adjustment of the heat curve. Prerequisite:
–
The suitable heat curve for the building is set in the Heat curve: function.
–
The correct zone is assigned to the system control or the remote control in the Zone
assignment: function.
–
Expanded is selected in the Room temp. mod.: function.
When a heat pump is connected, the system control automatically switches between heating
mode and cooling mode.
Cooling starts once the outdoor temperature (24-hour average) exceeds the set temperature.
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.
→ triVAl
The heat generator is selected based on the set tariffs in relation to the
heat demand.
→ Bivalence pt
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: Bivalence pt is selected in the Hybrid manager: function.
If the outdoor temperature falls below the set value, the system control activates the back-up
boiler in parallel with the heat pump.
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: Bivalence point is selected in the Hybrid manager: function.
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.
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.
Define what you want to deactivate when the signal is sent by the energy supply company.
The selection remains deactivated until the energy supply company cancels the signal.
The heat generator ignores the deactivation signal as soon as the frost protection function is
active.
→ Off
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.
→ Heating
The back-up boiler supports the heat pump during heating.
The back-up boiler is activated for the anti-legionella function.
→ DHW
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.
→ DHW + heat.
The back-up boiler supports the heat pump during domestic hot water
generation and heating.
Measured temperature, e.g. downstream of the low loss header
