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).

Function	WE	Configuration
Potentiometer in pre-control circuit	OFF	Co5 -> Fb16 = ON

Note!

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