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 control-
ler installed, it will either display a numerical error code
on the 7-Seg LED on the computer board (Only for the
510 models), display a blinking red LED (for the 110 &
310 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 & 310 models: The red LED on the computer board
will be blinking two times.
If the TK-RE02 is installed: “32” will display on the screen
in its entirety.
510 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 TM-RE30 is installed: “321” will display on the
screen in its entirety.

Easy-Link System
(For the 510 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 & #4: These units will not display anything, as the
error code does not pertain to them.
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.
