  • Timer controlled space thermostat with battery operated timer
    Patent number: 4049973
    Abstract: A timer controlled space thermostat includes a timer, a rechargeable battery for providing the electrical power to operate the timer, circuit means for recharging the battery, and two single-pole, double-throw temperature responsive switches. One conductive position of each switch enables the energizing of space conditioning apparatus control means, the other conductive position of each switch enables the energizing of the recharging circuit means, and the short timer period incidental to the movement of the switch between the conductive positions provides a sufficient time to ensure de-energizing of the space conditioning apparatus control means prior to the energizing of the recharging circuit means.
