Notes:
1. During the transition from off to any fan speed but high, Tracer
®
ZN.010 and ZN.510 automatically
starts the fan on high speed and runs for three seconds before transitioning to the selected speed (if it
is other than high). This provides enough torque to start all fan motors from the off position.
2. When the heating output is controlled off, ZN.010 and ZN.510 automatically controls the fan on for
an additional 30 seconds. This delay allows the fan to dissipate any residual heat from the heating source,
such as electric heat.
3. Whenever two states are listed for the fan:
The first state (off) applies when there is not a call for heating or cooling.
The second state (varies) applies when there is a call for heating or cooling.
The heat default is factory configured for low fan speed, and the cool default is medium.

Operation
The Tracer
®
ZN.010 and ZN.510 will operate in either continuous fan
or fan cycling mode. The fan cycles when the fan mode switch is
placed in auto. The fan runs continuous when placed in the high,
medium, or low position. Use Rover, installation and service tool,
to change the auto defaults.
