- If it flashes, the detector wiring may be faulty
- If it is lit, the controller is overridden by a remote operation
facility (room unit or changeover switch). Set room unit to
operating mode
or open the external switch)
4. Set operating mode selector to
5. Set heating curve potentiometer
to +8 °C:
- Flow temperature must rise: burner on, valve open, heat-
ing circuit pump on (electro-thermal actuators respond with
a certain delay!)
- If not: check wiring of the detectors (flow/boiler, outside de-
tector), actuator/burner and heating circuit pump
6. Set operating mode selector to .
7. Set heating curve to 0.25 and setting knob
- Burner must switch off (observe minimum running time of
4 minutes), valve must travel toward "colder", and heating
circuit pump must remain activated
- If not: check wiring of the detectors (flow/boiler, outside de-
tector), actuator/burner and heating circuit pump
Commissioning the remote operation facility

Settings on the controller
1. Set heating curve as specified in the planning documen-
tation or in compliance with local practices.
2. Reset setting knob
to 0 (factory-setting, corresponds
to 20 °C room temperature).
3. Leave setting knob
to –6 °C (factory-setting).
4. Set operating mode selector to one of the two

1. The D.h.w. temperature must be around 30 °C (check by
touching or use a measuring instrument).
2. Set the controller's operating mode selector to
3. Set setting knob
to 60 °C.
- D.h.w. temperature must rise: charging pump on or
changeover valve open
- If not: check wiring of the d.h.w. temperature detector and
the heating circuit pump, or the changeover valve
4. Set setting knob
to 10 °C (observe overrun time)
- Charging pump or changeover valve must switch off
- If not: check wiring of d.h.w. temperature detector
