Single Unit
• The 7-Seg LED displays the 3-digit error codes one digit
at a time. The remote controller (if installed) displays the
whole 3-digit error code at once.
Example:
If your unit has the “321” error code (inlet thermistor),
• The 7-Seg LED, will flash the 3-digit error code one digit
at a time. The 7-Seg LED will display “3”... “2”... “1”, and
then repeat the 3 digits.
• The remote controller, however, will display “321” on its
screen, in its entirety.
Easy-Link
• The 7-Seg LED on the PARENT unit displays a 5-digit
number 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 (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.
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.
