Abstract
A control system includes a remote temperature sensor configured to wirelessly communicate a signal indicative of a space temperature, and a return air temperature sensor configured to output a signal indicative of a temperature of return airflow within an air conditioning/heating unit. The system further includes a controller segregated from the space that is responsive to the signals from the sensors for determining a working sensed temperature based upon a temperature value associated with the return air sensor and at least one temperature value associated with at least one remote temperature sensor. The controller is configured to compare the working sensed temperature to a set-point temperature and responsively generate a command signal to activate the air conditioning or heating unit to control temperature relative to a set-point. The controller controls the air conditioning/heating unit at all times based upon the temperature value associated with the return air sensor.
