For the property owner
9.5.2 Settings
This is used to set the parameters for your home’s
heating requirements. It is important that this basic
setting is right for your home. Values which are set
incorrectly may mean that your property is not warm
enough or that an unnecessarily large amount of energy
is being used to heat your property.
9.5.2.1 Heating circuits 1-3
Max. primary flow °C 55 (30 to 80)
Maximum permitted temperature supplied to the
respective heating system.
Min. primary flow °C Off (Off/15 to 65)
Minimum permitted temperature supplied to the
respective heating system.
Heating off, outside °C 18 (10 to 30)
Outside temperature limit (B15) at which the house no
longer requires heating. The radiator pump stops, and
the mixing valve remains closed. The radiator pump
is activated daily for a short period to prevent it from
jamming. The system restarts automatically when
heating is required.
Heating off, time 120 (30 to 240)
When the outside temperature (sensor B15) falls to the
limit at which heating is required again, “ Heating off,
out °C” must remain this low or lower for this many
minutes before heating the house is permitted again.
Inclination 50 (25 to 85)
Inclination means the temperature your property needs
at different outdoor temperatures. See more detailed
information in the “Your home’s heating installation”
chapter. The value set is the outgoing flow temperature
to radiators when the outdoor temperature is -15 °C.
Curve adjustment 0 (-20 to 20)
The adjustment means that the temperature level can be
raised or lowered at a specific outdoor temperature.
!
Tip: Find out more about these set-
tings in the “Your home’s heating
settings” chapter.
For example:
“Inclination 50” means that the temperature of the water
supplied to the radiators will be 50°C when the outdoor
temperature is -15°C, if the adjustment is set to 0. If the
adjustment is set to +5, the temperature will be 55°C
instead. The curve is increased by 5°C at all outdoor
temperatures, i.e. the curve is parallel offset by 5°C.
