Low-Voltage Wiring
The gas heat control system requires a binary signal for
on/off control. A field provided interlock is recommended
in the start-stop signal circuit with the air handler supply
fan. This interlock must insure the start-stop signal is
interrupted to the gas heat system if the supply fan is shut
off. The gas heat system must not operate without the
supply fan providing airflow.
The control system also requires a 0 to 10 Vdc analog
signal for modulation where 10 Vdc is a signal for full heat.
NOTICE
Equipment Damage!
Do not operate the gas heat system without a supply
fan providing airflow. Operating the gas heat system
without a supply fan could result in damage to
equipment or property.
