16.3 CTKO4 Thermostat Wiring

NOTE: 

Refer to section Electrical Connections for 208/230

volt line connections to the air handler

.

NOTE: 

Use thermostat model that is later than 

CTK04AB.

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 sys-
tem components.  Two hundred fifty (250) feet is the maxi-
mum of wire between indoor unit and outdoor unit, or be-
tween indoor unit and thermostat.

16.3.1 Two-Wire Outdoor and Four-Wire Indoor Wiring

Typical wiring will consist of two wires between the indoor
unit and outdoor unit and four wires between the indoor
unit and thermostat.  Figure 20 shows the required wires
are: data lines, 1 and 2; “R” (24 VAC hot) and “C” (24 VAC
common).

16.4  ComfortNet™ System Advanced Features

The ComfortNet system permits access to additional system
information, advanced set-up features, and advanced diag-
nostic/troubleshooting features. These advanced features are
organized into a menu structure. See the AIR HANDLER AD-
VANCED FEATURES MENU section for layout of menu short-
cuts. The tables on page 21, section 17  show the air handler
advanced feature menus.

16.5 Network Troubleshooting

The ComfortNet system is a fully communicating system, con-
stituting a network. Occasionally the need to troubleshoot
the network may arise.  The integrated air handler control
has some on-board tools that can be used to troubleshoot
the network.  These tools are: red communications LED, green
receive (Rx) LED, and the learn button. Refer to the 

Commu-

nications Troubleshooting Chart

 at the end of this manual for

error codes, possible causes and corrective actions

•  Red communications LED – Indicates the status of the
network.  The  Communications Troubleshooting Chart on
the following  page indicates the LED status and the
corresponding potential  problem.
•  Green receive LED – Indicates network traffic.  The
following table indicates the LED status and the correspond-
ing potential problem.
•  Learn button – Used to reset the network.  Depress the
button for approximately 2 seconds to reset the network.
