ERROR CODES
The units are self diagnostic for safety and convenience when trouble shooting.
If there is a problem with the installation or the unit, depending on the model or if there is a
remote controller installed, it will either display a numerical error code on the 7‐Seg LED on the
computer board (for the 510 (T‐D2) models only), display a blinking red LED (for the 110 (T‐KJr2)
and 310 (T‐K4) models), or the error code will display on the remote controller if it is installed.
Consult with the table on the following page for the cause of each error code.
‐Single unit installations‐
Example: If your unit displays the “321” error code (which signifies an inlet thermistor failure)
110 (T‐KJr2) and 310 (T‐K4) models: The red LED on the computer board will be blinking two times.
If the remote controller 9007666005 (TK‐RE02) is installed: “32” will display on the screen in its
entirety.
510 (T‐D2) models: The 7‐seg. LED on the computer board will display “3”…”2”…”1” in that
order one digit at a time and continually repeat.
If the remote controller 9007603005 (TM‐RE30) is installed: “321” will display on the screen in
its entirety.
‐Easy‐Link system for the 510 (T‐D2) models only‐
Error codes will display 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 same error code is displayed in an Easy‐Link System.
Example: If Unit #2 has the “321” error code (inlet thermistor failure)
Parent unit: It will display “3”…”2”…”1”…”0”…”2” one digit at a time on the 7‐Seg LED. The first
3 numbers indicate the error code. The last two numbers indicate that Unit #2 has the error
code.
Unit #2: It will display “3”…”2”…”1
on the 7‐Seg LED, 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.
Remote controller 9007603005
(TM‐RE30): It will display “232” on
its screen. The first “2” indicates
that Unit #2 has the error. The
“32” indicates the first two digits of
the “321” error code.
