TROUBLESHOOTING PROCEDURES

The most common operating problems and types of errors
associated with the TEMP system thermostat are:
• Operating Problems. No display or flashing displays occur
when the TEMP system thermostat is not receiving rated
power or has miswired connections.
• Equipment Operating Problems. The TEMP system thermo-
stat does not select a system mode, does not energize the
associated unit, or does not energize the second stage of the
unit.
• Hardware Failure (HF) Errors. These errors occur when the
TEMP system thermostat detects a problem with one of its
own components or associated device.
• Storage Failure (SF) Errors. These errors occur when the
TEMP system thermostat detects and replaces faulty data
• System Errors (SE). These errors occur when the TEMP
