The Type 1G66 Electric Heat Thermostat is designed for use on all types of electrical heating installations such as cable heat, baseboards, wall insert heaters, etc.
The Type 1G66 thermostat is intended for use on 240 or 277 VAC where local codes require that a double line disconnect thermostat be used. This thermostat can also be used on 120 VAC. (See specific wiring information for 120 VAC.)

Dial Setting: This thermostat may be set anywhere between 40° and 80°F by simply turning the knob so the indicator on knob points to the desired setting.
The knob may be turned past 40° to the "OFF" position to obtain temporary shutdown of the heating equipment for short periods of time such as on weekends, vacation, etc. Turning knob to "OFF" position will break both sides of line.

Only one side of line is broken during normal cycling of this thermostat.
