5.14 Releasing the heating circuit
The release of the heating circuit in automatic mode is a default setting after the time schedule
has been programmed. In addition, it is possible to release the heating circuit over the corre
-
sponding potentiometer inputs. When no signal exists at these inputs and the slide switch of the
heating circuit is positioned to automatic mode ( ), the heating circuit is in stand-by mode (i.e.
just the frost protection is active).
Function
WE Configuration
Potentiometer input for release of HK OFF Co1, 2, 3 -> Fb12 = OFF
FrG-E: Release over binary signal (potentiometer)
FrG-A: Release over time schedule
with FrG-A:RLG: Configuration as per input
FREE: Input freely available
5.15 Position feedback in pre-control circuit
A potentiometer for position feedback (series resistor: 1000
Ω
) can be connected at terminal 27
instead of a potentiometer to shift the set point over the room sensor.
The actual position of the valve in the pre-control circuit is issued as an external resistance
value.
The valve position is displayed in % of the travel in the operating level at the end of the control
circuit data for the pre-control circuit (level 5).

OFF Co5 -> Fb16 = ON
Note!
The potentiometer input HK2 is not available when Co5 -> Fb16 = ON is configured.
