VAV Controller www.prolon.net 2.1.3 Temperature Configuration 2.1.3.1 PI controller Figure 2.1.9: Temperature configuration screen When a PI controller is used, the demand is calculated by adding the proportional component to the integral component. • Proportional: Defines the proportional band used by the VAV Controller to calculate the proportional component of the demand. Please refer to the following image. Setting this value to zero removes proportional control, and consequentially, integral control. Demand will always be zero and the controller will function as an Air Volume Controller.

VAV Controller www.prolon.net • Cooling Integral: Defines the amount of time required for the cooling integral component of the demand to equalize the proportional component. Setting this value to zero removes the cooling integral component of the demand. Units MIN MAX Default Minutes 0 120 15 • Heating Integral: Defines the amount of time required for the heating integral component of the demand to equalize the proportional component. Setting this value to zero removes the heating integral component of the demand Units MIN MAX Default Minutes 0 120 15 2.1.3.2 Setpoints • Default Heating Setpoint: When there is no exterior source (thermostat) supplying the VAV Controller with a heating setpoint, this is the value used as the heating setpoint. Units MIN MAX Default °C 5 30 21.5 °F 41 86 70.7 • Occupied Deadband: The deadband between the occupied heating setpoint and the occupied cooling setpoint. Units MIN MAX Default °C 0.5 15 1 °F 0.9 27 1.8 • Setpoints Limits: These are the minimum and maximum values of the setpoints. These values overwrite any input to the VAV Controller that is beyond their boundaries. Used during occupied mode ONLY. • Minimum Heating Setpoint Units MIN MAX Default °C 5 30 19 °F 41 86 66.2 • Maximum Heating Setpoint Units MIN MAX Default °C 6 44.5 25 °F 42.8 112.1 77 • Minimum Cooling Setpoints Units MIN MAX Default °C 5.5 44 20 °F 41.9 111.2 68 • Maximum Cooling Setpoints Units MIN MAX Default °C 6.5 45 26 °F 43.7 113 78.8 13 www.prolon.net info@prolon.net
