Inserting Clock Batteries
Power is supplied to the clock by two AAA
alkaline batteries (included). 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. The thermostat itself will
operate without batteries, but will not operate
as a fuel saver.
