ESCRIPTION
FEATURES
This furnace is a part of the ComfortNet™ family of products. The CTK0* ComfortNet thermostat kit allows this furnace to be installed
as part of a digitally communicating system. The ComfortNet system provides automatic airflow configuration, enhanced setup
features, and enhanced diagnostics. It also reduces the number of thermostat wires to a maximum of four. It may be also installed as
part of a non-communicating system using a standard 24 VAC thermostat.
This product may be installed with the ComfortNet thermostat and a non-ComfortNet compatible single stage air conditioning unit.
However, this reduces the benefits of the ComfortNet system as the enhancements will only apply to the furnace.
