Uni t Faul ts
The Thermolator has detected a problem with the internal components, wiring, electrical power, or operat-
ing environment. Without correction, the fault could lead to equipment damage or personal injury if it is
not corrected.
• The controller displays an error code indicating the cause of the problem.
• The TCU may take automatic control actions, based on the nature of the fault, to best protect the op-
erator and the TCU until the fault is corrected.
•
If the optional alarm package is installed, the fault strobe will illuminate and the audible alarm will
activate.
• Some faults require a power cycle to reset.
