If you have a Nicad battery: if the clock

stops after the fresh battery is installed,
move both temperature levers to the lowest
setting. The automatic recharging circuit is
then connected to the battery. Leave the
temperature levers at the lowest setting for
two to three hours; this will provide sufficient
battery charging to operate timer. The bat
tery will then automatically be recharged
whenever the thermostat is not calling for

heat or cool.

After replacing and charging the battery, let
the system cycle for at least threee hours,

then check to see that the clock is maintain

ing the proper time.

NOTE

If the Nicad battery is installed on a day when
extreme outdoortemperatures are experienced

and the heating or cooling system operate for
long periods of time, it may take as much as 24

to 48 hours to charge the battery. If you wish to
charge the battery more quickly, move the sys

tem switch to the OFF position. The battery then
will fully charge in approximately 3 hours (how

ever, the system will not operate with the
system switch in the OFF position).
