Most Thermolator malfunctions are indicated by an illuminat-
ed alarm light and error codes displayed on the control panel.
A problem can trigger three types of alarms:
l
Shut Down Alarms:
The Thermolator detected a problem
that caused it to shut down automatically to prevent equip-
ment damage or personal injury.
l
Warning Alarms:
The Thermolator continues to operate,
but warns of a problem that could lead to a condition that
will shut down the unit.
l
System Errors:
The system error codes indicate a non-
recoverable problem with the microprocessor control.
When the Thermolator control detects a problem, the red
Alarm light is activated and the RUN/STOP light changes
from green to flashing red.
