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).
