INSTALL CLOCK BATTERIES
Power is supplied to the clock by two AAA alkaline
batteries (included). Install clock batteries in
thermostat as shown. Once a year, or when batteries are
dead, replace with two new AAA alkaline batteries. We
recommend Energizer
®
batteries. Other types of batteries
are more likely to leak, which could damage the clock. The
thermostat itself will operate without batteries, but will not
operate as a fuel saver.

The two levers on top of the thermostat control the
low and high temperature for energy savings and
comfort control as shown in the illustration.

Do not check operation by shorting across
terminals of relay or valve coil; this will burn out the
thermostat heat anticipator, which will void the
warranty.
