ABSTRACT:
Electronic processing means, in combination with dedicated sensing apparatus is used to control the operation of an HVAC system which regulates the temperature in one or more temperature controlled spaces. The electronic processing means and associated sensing apparatus being readily adapted to existing HVAC systems through interface apparatus installed in each of the existing HVAC control lines associated with the HVAC sources of mixed air, hot air, and cold air, to provide selective actuation and modulation of the discharge air temperature from each source, individually or in combination, in response to sensed HVAC parameters including source discharge temperatures, space temperatures, outside air temperature, and the relative humidity of the outside air and return air from the spaces.
