VAV MODULATING Damper Thermostat AUTO CHANGEOVER
Young Regulator T-720 Series VAV Modulating Damper Thermostat. Proportional & Integral (P+I) Algorithm. Auto Changeover & Cooling only. 4075 / 3085 / 9100
Young Regulator T-720 Series Digital Thermostat is designed with a Proportional & Integral (P+I) Algorithm which speeds time to set-point and reduces overshoots.
The Heat / Cool T-720 A includes a changeover Duct Sensor. Sensor should be installed in the main supply trunk in a free air flow section. The T-720 B is for cooling only applications.
The T-720 A thermostat measures both room and duct temperature. Duct temperature below 72° indicates Cooling mode, temperature above 72° indicates Heating.
The thermostat measures room temperature and adjusts the damper to provide an appropriate amount of air depending on the distance to set-point. It initially opens the damper wide - then starts to close the damper as the temperature approaches set-point. This reduces overheating or cooling.
T-720 A - Heat / Cool with Duct Temp Sensor Probe
T-720 B - Cooling Only
T-720 IF - Heat / Cool with Duct Temp Sensor Interface - Installed in IF Dampers
