Easy-Link
The 7-Seg LED on the PARENT unit displays a 5-digit num-
ber to signify which unit in the Easy-Link system has the
error, and what the error code is. The 7-Seg LED displays
the number one digit at a time. The remote controller (TM-
RE30) (if installed) displays a 3-digit number which also
signifies which unit has the error, and what the error code
is. The unit that has the error in an Easy-Link system will
display the error code on its 7-Seg LED in exactly the same
way as if it were only a Single Unit. When the right and/or
left combustion section has an error code, the red lamp next
to the 7-Seg LED on the central computer board will flash to
indicate which combustion section has the error code. Refer
to the picture below.
Example:
If Unit #2 has the “321” error code (inlet thermistor),
The 7-Seg LED on the PARENT unit will display “3”...“2”
“1” “0” “2”, displaying only one digit at a time. The first 3
numbers indicate the error code. The last two numbers
indicate that Unit #2 has the error.
The remote controller, however, will display “232” on its
screen in its entirety. The first “2” indicates that Unit #2
has the error. The “32” indicates the first two digits of the
“321” error code.
The 7-Seg LED on Unit #2 will display “3”. “2”. “1”, just
like in the Single Unit example.
