Error Codes; General; Single Unit Installations; Easy-Link System For 510 Model Only - Takagi 110 Outdoor Installation Manual And Owner's Manual

• The water heaters have self-diagnostic functions for safety and convenience when troubleshooting.
• If there is a problem with the installation or the unit, the 510 model will display a numerical error code
on the 7-Seg LED on the computer board, and the 110 and 310 models will flash on a red LED on the
computer board. If a remote controller is installed, the error codes will be displayed on the remote
controller.
• Consult with the table on the following page for the description of each error code.
110 and 310 models
Red LED
flashes to indicate an
error code.
Example: If your unit has the "321" error code (which signifies an inlet thermistor failure)
• 110 and 310 models: The red LED on the computer board will repeat a pattern of two flashes.
• If the remote controller 100112183 (TK-RE02) is installed: It will display "32" on the screen.
• 510 model: The 7-Seg LED on the computer board will display "3", 2", "1" in that order, one digit at a
time, and it will repeat continually.
• If the remote controller 100112155 (TM-RE30) is installed: It will display "321" on the screen .
Error codes will be displayed differently with each unit installed in an Easy-Link System, not only to show
what the error code is, but also to indicate which unit within the system has the error code. Below is an
example 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)
• Remote controller 100112155 (TM-RE30): It will display "232" and on the display. The first "2"
indicates that Unit #2 has the error. The "32" indicates the first two digits of the "321" error code.
• Parent unit: It
"3"..."2"..."1"..."0"..."2", one digit at a
time on the 7-Seg LED. The first three
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 per-
tain to them.
