A programmable thermostat 45 is disposed at a location remote from a window air conditioning unit 10 controlled thereby. The thermostat has a temperature sensor 35 which itself is optionally remote from the thermostat. The thermostat may be programmed by a hand held remote control. The thermostat has a controller which selectively controls the on/off state of the air conditioning unit 10 in response to (1) a comparison of the time of day with program times stored in the memory to access a corresponding control temperature stored in the memory and (2) a comparison of the ambient temperature sensed by the sensor 35 and the control temperature stored in the memory. The system may log use of the air conditioner and indicate when the filter needs changing. <IMAGE> |
