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.

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
