General Information

BATTERY
The timeswitch is fitted with a non-rechargeable, long life battery, which will maintain the
programmed time settings for a minimum of ten months with the supply disconnected.
THIS SHOULD BE SUFFICIENT TO COVER POWER INTERRUPTIONS DURING THE
LIFE OF THE UNIT.
During power interruptions the display will be blank, after 3 days the current time of day will
be lost. These measures are to prolong the battery life.
SERVICE AND REPAIR
This timeswitch is NOT user serviceable. Please do not dismantle the unit.
In the unlikely event of a fault developing please refer to the RESETTING THE
TIMESWITCH section of this user guide . If this fails to resolve the problem please contact
your installer, a local heating engineer or a qualified electrician.
