EATURES
This air conditioner is a part of the ComfortNet™ family of prod-
ucts. It may be installed as part of a "legacy" system using a
standard 24 VAC thermostat. However, with the CTK0*
ComfortNet thermostat kit, this air conditioner may 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 num-
ber of thermostat wires to a maximum of four and a minimum
of two.
