Tracer™ ZN510 & ZN520 Unit Startup

Refer to the Trane publication, CNT-IOP-1 Installation, Operation and Programming Guide for Tracer ZN510 and CNT- SVX04A-EN for Tracer ZN520. The factory pre-programs the Tracer ZN510 and ZN520 with default values to control the temperature and unit airflow. Use Tracer Summit building automation system or Rover™ software to change the default values.

Follow the procedure below to operate the Tracer ZN510 or ZN520 in a stand- alone operation:

1.Turn power on at the disconnect switch option.

2.Position the fan mode switch to either high, medium, low, or the auto position.

3.Rotate the setpoint dial on the zone

sensor module to 55°F for cooling or 85°F for heating.

The appropriate control valve will actuate assuming the following conditions:

1.Room temperature should be greater than 55°F and less than 85°F.

2.For a 2-pipe fan-coil unit with an automatic changeover sensor, the water temperature input is appropriate for the demand placed on the unit. For example, cooling operation is requested and cold water (5° lower than room temperature) flows into the unit.

3.Select the correct temperature setpoint.

Note: Select and enable zone sensor temperature settings to prevent freeze damage to unit.
