Inserting Clock Batteries
Power is supplied to the clock by the 24 Vac
transformer. Backup batteries (not included) may
be installed to supply power to the clock when
power is interrupted. Install batteries in thermo-
stat as shown in Fig. 2. Once a year or when
batteries are dead, replace with two new AAA
alkaline batteries. We recommend Energizer
batteries.
