Heat circuit control

Weather-dependent control

The boiler or flow temperature is determined via the set
heat slope to suit the measured outside temperature in
such a way that the set value for the room is approximately
set if the heating system is configured correctly.

=> Exact setting of the heat slope is extremely important
for weather-dependent control.

The circulation pump is controlled weather-dependently.
The circulation pump is switched on if there is a heating
demand and in Frost-protection mode.

Room sensor influence

The current room temperature can be included in
computation of the required flow temperature via a present
room temperature sensor.

The influence factor (parameter list) can be set between 0
(fully weather-dependent regulation) and 20 (room
temperature regulation with minimal outdoor temperature
influence). Position "----" deactivates room temperature
control. Positions "----" and "0" indicate differences for
demand-dependent circulation pump control.

Hot water generation

The programmed hot water temperature is stabilised by
switching the hot-water cylinder charging pump and the
burner. Storage tank charging starts when the storage tank
temperature drops below the temperature setting by 5K.
Storage tank charging stops when the temperature setting
is reached.

OwB => operation without burner

For operation with solar energy for instance. In this
operating mode the burner is only enabled when values
drop below the set tolerance limit.

Frost protection function

The frost protection circuit prevents the heating system
from freezing by automatically switching heating operation
on.

Outdoor sensor frost protection

If the measured outside temperature drops below the set
frost protection temperature the room temperature setting
is set to 5°C for the relevant heating circuit. The heating
circuit is enabled:

•

the pumps are switched on

•

the heat request is sent to the boiler

"----" => outdoor sensor frost protection deactivated
