20.2 Control Wiring
NOTE: Refer to section Electrical Connections for 208/230 volt
line connections to the air handler .
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. One hundred and fifty (150) feet is the maximum
length of wire recommended between indoor unit and outdoor
unit, or between indoor unit and thermostat.
Only the data lines 1 and 2 are required between the indoor and
outdoor units. A 40VA, 208/230 VAC to 24 VAC transformer must
be installed in the outdoor unit to provide 24 VAC power to the
outdoor unit’s electronic control. See kit instructions for mount-
ing and wiring instructions.

20.4 ComfortNet™ System Advanced Features
The ComfortNet system permits access to additional system in-
formation, advanced set-up features, and advanced diagnostic/
troubleshooting features. These advanced features are organized
into a menu structure. See the AIR HANDLER ADVANCED FEA-
TURES MENU section for layout of menu shortcuts.
20.5 Diagnostics
Accessing the air handler’s diagnostics menu provides ready
access to the last six faults detected by the air handler. Faults
are stored most recent to least recent. Any consecutively re-
peated fault is stored a maximum of three times. Example: A
clogged return air filter causes the air handler’s motor to repeat-
edly entera limiting condition. The control will only store this
fault the first three
consecutive times the fault occurs.
NOTE: It is highly recommended that the fault history be cleared
after performing maintenance or servicing the air handler .
20.6 Network Troubleshooting
The ComfortNet system is a fully communicating system, and
thus, constitutes a network. Occasionally the need to trouble-
shoot the network may arise. The integrated air handler control
has some on-board tools that may be used to troubleshoot the
network. These tools are: red communications LED, green re-
ceive (Rx) LED, and learn button. Refer to the
Communications
Troubleshooting Chart at the end of this manual for error codes,
possible causes and corrective actions.
• Red communications LED – Indicates the status of the net-
work. The table below indicates the LED status and the
corresponding potential problem.
• Green receive LED – Indicates network traffic. The
COM MUNICATIONS TROUBLESHOOTING CHART indicates
the LED status and the corresponding potential problem.
• Learn button – Used to reset the network. Depress the
button for approximately 2 seconds to reset the network.
20.7 System Troubleshooting
NOTE: Refer to the instructions accompanying the ComfortNet
compatible outdoor AC/HP unit for troubleshooting information.
Refer to the
Troubleshooting Chart at the end of this manual for a
listing of possible air handler error codes, possible causes and
corrective actions.
