Releasing The Heating Circuit; Position Feedback In Pre-Control Circuit - Samson TROVIS 5179 Mounting And Operating Instructions

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 (
just the frost protection is active).
Function
Potentiometer input for release of HK

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
Potentiometer in pre-control circuit
Note!
The potentiometer input HK2 is not available when Co5 -> Fb16 = ON is configured.
