Resetting Diagnostics

The following methods describe resetting unit diagnostics:

•

High/Low Pressure Cutout

•

Manual Output Test

•

Cycling Power

•

Building Automation System (BAS)

•

Tracer TU Service Tool

•

Cycling the Fan Switch

High/Low Pressure Cutout

The UC400 Controller includes a one-time automatic diagnostic reset function. This function
automatically recovers a unit when the High/Low Pressure Cutout diagnostic occurs. When this
diagnostic occurs, the controller responds as defined in

“Diagnostics,” p. 47

. After the controller

detects the High/Low Pressure Cutout diagnostic, it waits 30 minutes before invoking the
automatic diagnostic reset function. The automatic diagnostic reset function clears the High/Low
Pressure Cutout diagnostic and attempts to restore the unit to normal operation. The controller
resumes normal operation until another diagnostic occurs. If a High/Low Pressure Cutout
diagnostic reoccurs within 24 hours after an automatic diagnostic reset, the diagnostic requires a
manual reset.

Manual Output Test

The service button on the UC400 Controller can be used during installation to verify proper end
device operation, or during troubleshooting. When the service button is pressed, the controller
exercises all outputs in a predefined sequence. The first and last steps of the sequence reset the
controller diagnostics.

Cycling Power

When turning off the 24 Vac power to the UC400 Controller and then powering on again, the unit
cycles through a power-up sequence and clears all timers. By default, the controller attempts to
reset all diagnostics at power-up. Diagnostics presented at power-up, and those that occur after
power-up, are handled according to the defined unit diagnostics sequences.

Building Automation System (BAS)

Some building automation systems can reset diagnostics in the Tracer unit controller.

Tracer TU Service Tool

The Tracer TU service tool can be used to reset diagnostics in the UC400 Controller (from the
Alarms tab).

Cycling the Fan Switch

If the user cycles the fan speed switch from off to ON or AUTO, the UC400 Controller resets all
diagnostics. Diagnostics may immediately recur if the problem still exists.
