Inserting Timer Batteries

(Optional)

Power is supplied to the timer by the 24 Vac

transformer. Two AAA alkaline backup batter-

ies (not included) may be installed to supply

power to the timer if power is interrupted due to

power failure. Install the batteries in the

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.
