2 Applications Basic Operation The Unit Vent Controller⎯0 to 10V Output provides Direct Digital Control (DDC) technology for unit ventilator applications.
Basic Operation Day Cooling Operation The controller maintains the room temperature by resetting the unit ventilator's discharge temperature setpoint (2281), running the face-bypass damper at full all the time, modulating or cycling the available coil control device (DX coil – 2284) or positioning the outdoor air damper. Night Heating Operation The controller maintains the room temperature turning the fan and heating on and off as required.
APOGEE Unit Vent Controller⎯0 to 10 V Output Owner’s Manual Cooling Loop – maintains room temperature setpoint by turning valves on and off and using free cooling (mixed air control) when available. Auxiliary Loop – modulates the auxiliary loop using the auxiliary setpoint and discharge setpoint (2284). Mixed Air Loop – modulates the mixed air loop using the mixed air setpoint and mixed air temperature (2283). DX Loop – modulates the cooling loop using the control setpoint and room temperature (2284).
Basic Operation If the room temperature sensor input to the Unit Vent Controller fails or the LTDT equals ON, the controller goes through the following shutdown sequence: • Outdoor air damper is closed. • Heating is full ON (except electric, which is OFF). • Cooling is full OFF. • Face-bypass damper is open to face. • Fan is OFF. • Auxiliary radiation is OFF. • Two-position heating valve actuator is open. • Two -position cooling valve actuator is closed.
