5.0 AIR HANDLER Comfort Control 2 System™
INTERFACE BOARD
FIGURE 8
THE AIR HANDLER CONTROL BOARD EQUIPPED WITH THE Comfort Control2 System™
For the Comfort Control 2 System™, you must have:
• An air handler equipped with the Comfort Control 2 System™
• A condensing unit or heat pump equipped with Comfort Control 2 System™
• A Comfort Control 2 thermostat
If your equipment does not meet this criteria, you must wire it using conventional 24VAC
thermostat control wiring. Reference Section 5.11.
5.1 Comfort Control 2 CONTROL WIRING
The Comfort Control 2 requires four (4) control wires for unit operation:
R – 24VAC
C – 24VAC common
1 – Data wire 1
2 – Data wire 2
Wiring sizing for Comfort Control 2 is identical to systems using low voltage 24V wires.
No t e: Comfort Control 2 requires a minimum 18 AWG.
IMPORTANT: When using Comfort Control 2, do not make any connections to the
24VAC thermostat wires. If any connections are made to the G, W1, W2, Y1, Y2, B, or
ODD wires, the Comfort Control 2 control will assume the control is being used with a traditional thermostat and will IGNORE ANY COMMUNICATIONS USING DATA WIRE 1
AND DATA WIRE 2.
IMPORTANT: Class 2 low voltage control wire should not be run in conduit with power
wiring and must be separated from power wiring, unless Class 1 wire of proper voltage
rating is used.
• The four 18AWG low voltage control wires must be installed from the thermostat to the
indoor unit and from indoor unit to the outdoor unit. The wire length between the thermostat and indoor unit should not be greater than 100 feet. The wire length between
the indoor unit and outdoor unit should not be greater than 125 feet.
• Low voltage control connections are made by extending wires from top of air handler
using wire nuts.
• See wiring diagrams attached to indoor and outdoor sections to be connected.

Comfort Control 2 System™ CONTROL WIRING
The RHPL-series of air handlers are designed to operate with conventional 24VAC controls or with a serial communicating system.
• Do not leave excess field control wiring inside unit, pull excess control wire to outside
of unit and provide strain relief for field wiring on inside of cabinet at point wiring penetrates cabinet.
• Make sure, after installation, separation of control wiring and power wiring has been
maintained.

5.2 Comfort Control 2 System™ CONTROL BOARD
The RHPL series air handler control, Figure 8, has the following features:
• Memory Card – The memory card stores all information needed for unit operation.
Once the system is wired for serial communications, this information is shared with the
thermostat and outdoor unit. This shared data is available if one of the components in
the system needs to be replaced.
• An automotive-style ATC blade fuse for transformer protection (3 amp).
• An on-board LED to indicate blower CFM.
• An RJ-11 port for use with a diagnostic tool.
• Inputs for field installed supply and return air temperature sensors (available in kit
RXHT-A01)
• DIP switches for airflow adjustments
IMPORTANT: The DIP switches are NOT used when the air handler is wired for serial
communications. Airflow adjustments are performed via the thermostat or a diagnostic
tool.
Installation Verification
• Term and bias dip switches should be on.
• 24V AC power on R&C must be present at the control for the air handler to operate,
reference Figure 9.
• Line voltage must be present at the control for indoor blower operation.
• The RX Data LED will flash green in normal operation. A flashing green light indicates
24VAC is present and the data wires 1 and 2 are wired properly.
IMPORTANT: If the RX DATA LED is solid green, data wire 1 and data wire 2 are not
properly connected. Typically, the connections are switched, i.e. data wire 1 is wired to
the data wire 2 connection and data wire 2 is wired to the data wire 1 connection. Verify
wiring and correct the polarity at the two data wires.
IMPORTANT: Diagnostic port is for the diagnostic tool only. Do not attempt to connect
components using a telephone cord. Damage will occur.
IMPORTANT: Diagnostic port is not a phone jack. Connecting to a telephone or telephone system will result in damage.
5.3 USING THE ON-BOARD LED TO DETERMINE BLOWER CFM
The CFM LED indicates blower output by flashing one (1) flash for every 100 CFM of
airflow. The LED will pause 1/10 second between each flash.
5.4 AIRFLOW ADJUSTMENTS WITH THE Comfort Control 2 System™
The RHPL air handler Comfort Control 2 System™ may operate using the Comfort
Control 2 or via traditional thermostat wiring. When the air handler is wired for the
Comfort Control 2 using Data wire 1 and Data wire 2, the DIP switches on the Comfort
Control 2 control have NO affect on the airflow.

5.10 COOLING DELAY PROFILES
The RHPL air handler is factory configured with optimum ON/OFF delays to maximize
energy efficiency and comfort. In certain situations, the installer may choose an alternate
profile to tweak the system operation for the building load and to maximize comfort. The
alternate profiles are defined below:
IMPORTANT: On Demand Dehumidification, ODD, is the preferred method to maximize
comfort with little or no loss of energy efficiency. If using ODD, do NOT use any of the
alternate profiles. Only use the factory default profile. Use of the alternate profiles with
ODD will decrease energy efficiency with no gain in comfort.
