Note:
1. 2-pipe hydronic heat/cool changeover units use terminals J1-5 and J1-6 to control the primary valve for both heating and
cooling. Units configured and applied as 2-pipe hydronic heat/cool changeover with electric heat, use terminals J1-5 and
J1-6 to control the primary valve (for both cooling and heating), and terminals J1-9 and J1-10 for the electric heat stage.
For those 2-pipe changeover units, electric heat will not energize while the hydronic supply is hot (5 or more degrees
above the space temperature). In a four-pipe application, pin J1-5 is for cooling and pin J1-6 for heating.
2. If no valves are ordered with the unit, the factory default for Tracer ZN010 and ZN510 controllers are:
main valve configured as normally closed
aux. valve configured as normally open
3. If the fresh air damper option is not ordered on the unit, 2-pos. damper is configured as none.
4. Pin J1-2 can be configured for an exhaust fan with the use of Rover Software.Factory default is none.

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.
