ERROR CODES
-General-
•
The units have self-diagnostic functions for safety and convenience when troubleshooting.
•
If there is a problem with the installation or the unit, the error code will be displayed on the
temperature controller and remote controller.
•
Consult the table on the following pages for the description of each error code.
-Single unit installation-
Example: If your unit has the “321” error code (which signifies an inlet thermistor failure)
•
Indicator on the built-in controller and/or remote controller:
“321” will be displayed on the screen.
•
Green LED on the computer board:
The green LED on the computer board will indicate this code with
two flashes every 1/2 second. The pattern will repeat with a three second delay between patterns.
-Easy-Link System-
(For the 510C model only)
Error codes will be displayed differently with units installed within an Easy-Link System, not only to show
what the error code is, but to also indicate which unit within the system has the error code. Below is a
sample of how the error code of "321" is displayed in an Easy-Link System.
Example: If Unit #2 has the “321” error code (inlet thermistor failure)
•
Indicator on the built-in controller
and/or remote controller of Parent unit:
“321” and "2" will intermittently flash on
the display.
•
Unit #2:
"321" will intermittently flash on the display.
The green LED on the computer board will
flash twice, just like in the single unit example.
•
Unit #3 and #4:
These units will not display anything,
as the error code does not pertain to them.
