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
