4.12. Menu structure
By pressing the set/reset button in for longer than 5 seconds, you go to the ‘mode’ menu.
To change the subsequent "Letter" parameter, the user must press the Set/Reset button.
To change the “Range” setting in the parameter, the user must press the “+” or the “–“ button.
Letter Description Range Factory setting Field of application
C
max. set point of central heating 25°C - 90°C 82°C
O

If you switch back to the factory setting,
this has no effect on the H, S and P/S
settings

In the View mode, you can read the actual values of:
8 = Water pressure (in bar)
1 = Flow temperature (in °C)
2 = Return temperature (in °C)
3 = Inlet cold water temperature / HWS sensor (in °C)
4 = External temperature (in °C)
5 = External cylinder temperature (in °C)
6 = Flue gas temperature (in °C)
7 = Flame signal (in μA DC)
9 = Last interlock
A = Last blocking
