Emerson WHITE-RODGERS 1A66/1A66W ELECTRIC-HEAT THERMOSTAT
The Type 1A66/1A66W Electric Heat Thermostat is designed for use on all types of electrical heating installations such as cable heat, baseboards, wall insert heaters, etc. Its narrow operating differential and the ability of its fully exposed knob to sense both radiant heat and room air temperature make this control ideal for use on such installations.
The Type 1A66/1A66W is intended for use on 240 or 277 volts where local codes require that a double line disconnect thermostat be used. Dial Setting: Knob may be set anywhere between 40° and 85°F by simply turning knob so that 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.
This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction. Take care not to push or damage the knob sensing element during installation. All wiring must conform to local and national electrical codes and ordinances.
