About Your New Thermostat...

Your new thermostat can save 10 to 16% on annual heating fuel bills, depending on the climate of
the city where you live. With the fuel you save, the thermostat can pay for itself in less than one year
in most locations. Settingtemperaturesloweralso provides additional comfort. Most families enjoy
sleeping in cooler temperatures in both summer and winter. Your thermostat will automatically
maintain comfortable temperatures for you.

NOTE

This operation guide is a universal manual
for all variations of the entire line of mechani
cal clock thermostats. Your thermostat may

not have every feature and may vary slightly.

Please read this manual thoroughly before installing, operating or programming your

thermostat. If you have questions, please write to us at the address shown on the back cover
