h) Emergency operation of the valve operating mechanism
If an error occurs that cannot be eliminated (be-
cause the batteries of the heating control or valve
operating mechanism are low and no new batter-
ies are at hand, for example) it may be necessary
to operate the valve manually. To do so, proceed
as follows:
• Remove both batteries from the valve operating
mechanism.
• Remove the control pin by pressing on the
position marked with a (
1

• Place the control pin onto the peg marked with
a (

• Turn the control pin:

Clockwise = increase heat
-
Anticlockwise = reduce heat
