Guidelines
•
Do not install both the 2-Unit connection cable and
the Multi-Unit connection kit because they are not
designed to operate together.
•
Water heaters should be installed less than 18
inches apart so that the cables will reach between
units and to prevent temperature fluctuations (cold
water sandwich effect) when the water is shut off
and turned back on.
•
Temperature settings can only be changed on the
controller for the primary unit.
WARNING
DO NOT adjust the other dip
switches unless specifically
instructed to do so.
