Failure Modes

When any condition results in the rooftop unit’s inability to

perform a normal function, it is said to have entered a
failure mode. There are two types of failure modes.

1. An “Analog input out of range” failure mode.

This failure mode occurs when a sensing device such

as a zone temperature sensor or a humidity sensor
begins to transmit information that is outside its
allowable range.

2. A “Fault recognition by input logic” failure mode.

This failure mode occurs when the UCM receives

information that does not “make sense” or does not
conform to its predefined logic.

Diagnostics Types

There are three types of diagnostics:

Informational - Does not affect machine operation.

2. Automatic Reset - Affects machine operation but

returns to normal when diagnostic condition no longer
exists.

3. Manual Reset - Affects machine operation and must be

reset at the HI or by cycling power to unit for normal
operation to resume.

To troubleshoot diagnostics, reference the Installation,

Operation, and Maintenance Manual SCXF-SVX01*-EN

that ships with the Signature Series units and SCXG-
SVX01*-EN that ships with the Modular Series units.
