Horstmann C27 Manual

The programmer 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.
