4. In the unlikely event of it developing a fault, contact
your Gas Safe Registered Installer or Service Engineer,
but before doing so try the RESET PROCEDURE above.

maintain the programmed ON/OFF settings for a period
in excess of 2 years (Part No. 5118231).
2. This is more than sufficient to cover all the expected
power interruptions during the life of the unit.
NOTE: If a power interruption of more than 48 hours
occurs the 'time of day' will need to be re-adjusted
once the power is restored.
