A line voltage controller/thermostat for heating and cooling systems. The controller includes a bulb-and-capillary temperature sensor operating a line voltage load current switch. The load current switch is back-mounted on a deck plate adapted for covering a single width wall outlet box with the load switch recessed therein. Separate manually operated line voltage function (fan) switches are front mounted on the deck plate and protected by an impact resistant electrically insulating plastic housing thereover retained on the deck plate by fasteners accessible only from the backside. An outer decorative cover extends over the plastic switch housing and the sensing bulb with an adjustment shaft extending therethrough with adjustment knob thereon.
