Document No. 550-164 Installation Instructions October 26, 2016 CAUTION Wiring Diagrams DO Wiring – Each DO provides a Normally Open (NO) terminal and a Common (C) terminal. To reduce noise and the potential for ground loops, both connections of a 24 Vac load must be wired directly to the DO terminal on the controller board. Offboard Air Module Wiring. 8. 9. Plug the room temperature sensor cable into the RTS port. Connect the power trunk.

Document No. 550-164 Installation Instructions October 26, 2016 CAUTION NOTE: When wiring any actuator that uses a 0 to 10V control signal and ties AC neutral to DC common, an additional wire must connect the actuator AC neutral to the DC common of the PTEC/TEC AO being used to control the actuator. Each 4-20 mA sensor requires a SEPARATE dedicated power limited 24 Vdc power supply. DO NOT use the same transformer to power both the sensor and the controller.
