Operating instructions

m) Radiator offset (‘

OFFSOFFS

OFFS’)

This setting option is only displayed, if you use more than one valve operating

mechanism.

If several radiators are controlled by one heating control, it may be that these radiators do not

heat up to the same level.

The reason for this is that the flow rates of the valves differ greatly, depending on

varying or poorly dimensioned radiators. This problem may be solved by adjusting

the settings of single radiators so that they give off more (positive offset) or less

(negative offset) heat.

• Press the ‘PROG’ button until ‘

• Use the scroller to select the special ‘

OFFS’ function.

• Use the scroller to select the valve operating mechanism/radiator you require, and confirm

your selection by pressing the ‘PROG’ button.

• Use the scroller to set the offset, and confirm your setting by pressing the ‘PROG’ button.

The heating control then returns to the normal operating mode.

You may have to repeat this process several times until the heating power has been

optimally distributed.
