Adjustment heating curve (in case of an outdoor temperature sensor)
By pressing the set/reset button in for longer than 5 seconds, you go to the ‘mode’ menu.
To change the subsequent "Letter in menu" 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.
Parameter „C“
The setting in the menu „C“ makes the maximal heating flow
temperature (default 82°C).
O/b-value:
The setting of the minimal Heating flow temperature
(value in °C).
O/S-value :
The setting for the sloop of the curve.
( change of Flow temperature depending on the change of the
outside temperature).
O/d-value :
The setting of the flow temperature at an outside
temperature of 20°C (value in °C).
