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-

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.
