Remote Thermostat Control

Multiple Units Connected to One Remote Thermostat (2500 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.
