Wiring Notes:
1. If you use the same power source for the heating stages, install a jumper across RC and RH. Maximum current is 2.0 amperes.
2. If you use the auxiliary output to toggle occupancy of the electronic control card inside the equipment, configure the relay
parameter (Aux Cont) to the Normally Open (N.O.) setting. A second relay can be added for additional occupancy input functions.
3. The humidifier output uses a half-bridge rectifier. The control signal reference is the controller power supply common (terminal C).
4. Electromechanical contacts are used with the digital input. Electronic triacs cannot be used for input switching. Use
terminal C (common) for the switching leg of the digital input.
5. The unit transformer provides power to the controller and the additional loads that are wired to the controller.
