10. Emergency operation of the valve operating mechanism
If an error occurs that cannot be eliminated (because the batteries of the heating
control or valve operating mechanism are low and no new batteries 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 correctly onto the peg marked with a (2).
• Turn the control pin:
- Clockwise = increase heat
- Anticlockwise = reduce heat
