Analog Inputs
Binary Outputs
Binary outputs are configured to support the following:
•
•
Two fan stages (when one or two fan stages are present, J1-2 can be configured as exhaust fan)
•
One hydronic cooling stage
•
One hydronic heating stage (dehumidification requires this to be in the reheat position)
•
One DX cooling stage
•
One or two-stage electric heat (dehumidification requires this to be in the reheat position)
•
Face and bypass damper
•
Modulating fresh air damper (Tracer™ ZN520 only)
•
One-stage baseboard heat

Notes:
1. The zone sensor, entering water temperature sensor, discharge air sensor, and the outside air temperature sensor are 10KW thermistors.
2. Zone sensor: Wall mounted sensors include a thermistor soldered to the sensor’s circuit board.
3. Changeover units include an entering water temperature sensor.
