programme by means of the SELECT button.

General Information
Battery
The programmer is fitted with a non-rechargeable, long life
battery, which will maintain the programmed time settings for a
minimum of two years 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; this is to
prolong the battery life.
Service and Repair
This programmer is NOT user serviceable. Please do not
dismantle the unit.
In the unlikely event of a fault developing please refer to the
RESETTING THE PROGRAMMER section of this user guide
shown above. If this fails to resolve the problem please contact a
local heating engineer or a qualified electrician.
