3. LING TO ACHIEVE SETPOINT TEMPERATURE SETPOINT TEMPERATURE ZONE CONTROLLER SHOWN IN AUTO MODE HOW DOES THE ADVANCED AIR CONTROL SYS TEM WORK The Advantage Air single VAV works by measuring the temperature in the zone room temperature then compares the zone temperature with the setpoint and the system supply air temperature The VAV then takes the necessary action to reduce or increase the amount of air entering the room to enable the room temperature to match the setpoint It should be noted that the VAV can only make use of the supply air temperature being provided by the air conditioning unit The VAV cannot provide heating while the A C unit is running in a cooling mode In the event that the zone requires cooling while the A C unit is in a heating mode the VAV will close of the air supply to the zone until such time as cool supply air is available I VAV 7 ADVANTAGE AIR SINGLE VAV CONTROLS ADVANTAGE AIR SINGLE VAV USER MANUAL SYMPTOM POSSIBLE CAUSES REMEDY Zone too hot Zone too cold REVISION 05 10 02 A C unit not running A C unit control setpoint too high Zone controller on standby Zone controller setpoint too high A C unit not running A C unit control setpoint too low Zone controller on standby Zone controller setpoint too low Switch A C unit on Adjust A C unit control setpoint down Switch zone controller out of stand by and into auto mode Adjust zone co
