ABSTRACT:
A remote control system for a rotatable thermostat. The protective cover of a state-of-the-art thermostat is removed and a device responsive to remote control signals is substituted therefor. A drive wheel engages the thermostat dial and a control circuit determines the direction of rotation of the drive wheel. The thermostat dial is rotated in increments of 1.degree. F. A rod engages the drive wheel and extends through the housing of the device such that the drive wheel may be accessed without removing the device. When it is desired to manually rotate the thermostat, the rod disengages the drive wheel from the thermostat dial.
