Function description
Heating circuit control unit
Brief description
The set supply temperature of every heating circuit is
selected by the following parameters:
Outdoor temperature
Set room temperature
Operating mode
Heating curve
The supply temperature of the mixing valve circuits is
regulated by the stepped opening or closing of the mixing
valves.
Functions
Time program
The control unit time switch changes in accordance with the
programmed times in the central heating program between
the central heating with standard temperature and central
heating with reduced temperature operating modes.
Every operating mode has its own
set value level.
Outdoor temperature
A heating curve must be set up for matching the control unit
to the building and the heating system.
The heating curve characteristics determine the set supply
temperature subject to outdoor temperature. An average
outdoor temperature is used for control purposes. This
comprises the actual and the adjusted outdoor temperature.
30
The mixing valve motor control changes the actuating and
pause times subject to the control difference
(control deviation).
Coding addresses which influence the heating circuit control
9F, A0 to Fb.
For a description, see the coding overview.
Domestic hot water temperature
With priority control:
