Remote Thermostat Control
Multiple Units Connected to One Remote Thermostat
(2800 Series)
One remote control thermostat may be used to control
multiple resistance heat Zoneline units, however the units
may not be wired direct. Since each Zoneline unit has an
integral transformer, direct wiring can result in a “bucking”
or boosting” voltage condition, and is in violation of the
National Electric Code. The diagram below shows the
correct wiring for such an installation through the use
of field supplied isolation relays.
