Inserting Clock Batteries
Power is supplied to the clock by the 24 Vac transformer, by two AAA alkaline batteries (included), or by the heating or cooling control circuit. Backup batteries may be installed to supply power to the clock if power is interrupted when using 24 Vac powering method. Install batteries in thermostat as shown in
Fig. 2. Once a year or when batteries are dead, replace with two new AAA alkaline batteries. We recommend Energizer® batteries.

Daylight Savings Time
When Daylight Savings Time starts, move the minute hand carefully in a clockwise direction one hour. When Daylight Savings
Time ends, move the minute hand carefully in a clockwise 
direction 23 hours. Do NOT reverse the minute hand, or damage to timer mechanism may occur.
