The unit is designed to work as part of a fully communicating
HVAC system, utilizing a ComfortNet™ CTK04 thermostat,
ComfortNet compatible indoor unit, and up to four wires. Route
control wires through the low voltage port and terminate in ac-
cordance with the wiring diagram provided inside the control
panel cover.
Voltage Ports

NOTE: A removable plug connector is provided with the control
to make thermostat wire connections. This plug may be removed,
wire connections made to the plug, and replaced. It is STRONGLY
recommended that you do not connect multiple wires into a single
terminal. Wire nuts are recommended to ensure one wire is used
for each terminal. Failure to do so may result in intermittent
operation.
Typical 18 AWG thermostat wire may be used to wire the system
components. However, communications reliability may be im-
proved by using a high quality, shielded, twisted pair cable for
the data transmission lines. In either case, 250 feet is the maxi-
mum length of wire between indoor unit and outdoor unit, or
between indoor unit and thermostat.

WO
Low voltage wiring consists of two wires between the indoor unit
and outdoor unit and four wires between the indoor unit and
thermostat. The required wires are data lines 1 and 2, "R" (24 VAC
hot) and "C" (24 VAC common).

The heat pump unit is shipped with a predetermined factory charge
