A system and method for controlling tho operation of a Heating, Ventilation and Air Conditioning (HVAC) system for use primarily in a building having mote than two controllable temperature zones. Rooms having a priority for heating or cooling are identified as such in a controller. The controller sums Temperature Differences from all controller spaces and causes the HVAC system to operate in a first mode (e.g. heating) if the sum has a first relationship to a preselected val ue (e.g. sum > = 0) and causes the HVAC system to operate in a second mode (e.g. cooling) otherwise. |
