Assigning Unit Numbers In The Easy-Link System - A.O. Smith 710 ASME Service Manual

12-6. Assigning unit numbers in the Easy-link system

A.
How to display the unit number
Press the "Unit # display" button on the computer board. The 7-seg LED will then display the
assigned number for that 710 unit for 10 sec.
NOTE: In a single-unit installation, the numbering system is disabled.
B. How to reset and reconfigure the numbering of units
Unit #'s can be reset and reassigned manually:
1. Press and hold the "Unit # display" button on the computer board of all child units for at least 5
seconds.
2. The 7-seg LED on the computer board of all child units will display "0" to signify that the computer
memory has been erased of its previously assigned unit #.
3. Press and hold the "Unit # display" button again. New unit # will be assigned in order as you
proceed through every unit.
7-seg LED
Each 710 in an Easy-link system is assigned a random unit #, except for the
Parent unit, which is always assigned as unit #1.
When more than four units of the 710 are connected in an Easy-link system,
only the first four units will work as a system. The remaining units will not
operate.
