Installation
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
startup
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.
