<p>A two terminal line voltage thermostat includes a switch (22) which effectively connects line voltage to a heater load. The entire process is controlled by an integrated circuit micro-controller (10) which is powered by a rectified voltage from a transformer secondary connected to a primary which is in series with the heater load. Backup battery (11) power is provided to maintain limited functions of the micro-controller in the event of overall power loss. The micro-controller is programmed to meet the temperature sensing (18) and control requirements specific to a two terminal electric baseboard heating installation.</p> |
