The VVR default logic operates whereas the board activates the CCW board output to open the damper. To connect
the actuator to the damper shaft to open in a CLOCKWISE rotation:
1.
Make sure the damper is closed, and the existing actuator is in the full
counter-clockwise position.
2.
Connect the existing 3-wire floating actuator with 2-pair cable as shown in Figure 6.
3.
Set the address DIP switch as required per Appendix 1.
4.
Connect the low voltage power to the unit per the next section.
5.
Connect temperature sensors per additional sections of this manual.
6.
Connect fan or heating stages per additional sections of this manual.
7.
Connect modulating reheat valves per additional sections of this manual
