A NOTE: If Conventional is Selected Proceed to Stages Cool.
COMMON CONTROL SETUP
Minimum On Time
Default: 2 minutes. Select between 0-5 Minutes. The value is
displayed on the main display. The system will operate for a
minimum of 0 minutes to 5 minutes depending on your setting.
FEATURES
CLK Terminals
Selects between Occupied and Unoccupied operation using a
dry contact closure. A shorted contact between CLK1 and
CLK2 places the thermostat in Unoccupied operation.
Removing the short places the thermostat in Occupied
operation.
If Heat Pump is selected, proceed to # of Compressors.
5. Reattach faceplate to backplate by placing the top of the
faceplate over the top lip of the backplate.
Stages Cool
6. Gently swing the thermostat down and press on the
bottom center edge until it snaps in place. This is a tight
connection, but may require a little wiggle to align the pins
on the faceplate with the screw terminals on the backplate
before it snaps into place.
Default: 2 Select between 1 or 2 Stages Cool. The value is
displayed in the main display.
Minimum Off Time
Default: 4 minutes. Select between 2 to 5 Minutes. The value is
displayed on the main display. The system will allow equipment
recovery for 2 to 5 minutes before turning on again.

Calibration Offset
The thermostat and remote sensors are pre-calibrated at the
factory, but in some installations, lack of airflow at the sensor or
proximity to other warming or cooling sources may cause the
temperature to be off by a few degrees. The X5-CFA thermostat
includes a temperature calibration offset with a range of ±6˚F
(±3˚C) in 0.2˚F (0.1˚C) increments.

Compressor Configuration. For two compressors setup go to
Two Compressor Configuration.
A NOTE: If the Aux/EHeat ON is selected, proceed to Heat Pump
Option. Otherwise, proceed to the Minimum On Time option.
The X5-CFA thermostat uses one or more NT-ROOM-S remote
sensors for temperature control. See the NT-ROOM-S
installation instructions for details.

INSTALLER MENU
Press and hold the MODE Button
If the thermostat is being used as a Heat Pump thermostat and
current weather conditions are enabled or an outdoor sensor is
connected to the remote sensor terminals, the thermostat can
be configured to disable the use of auxiliary heat during
warmer weather and to lock out the compressor during colder
weather. If the weather conditions are enabled the high and
low balance point settings are available in the installer menu.

After a power failure, the thermostat will delay the HVAC
equipment start-up by 1-24 seconds. When multiple NetX™
X-Series thermostats are used, this minimizes the “in rush”
current (electric power usage) as it reduces the number of
HVAC units that will be turned on simultaneously.

Thermostat Address
Default: 1 Sets the thermostat address for communications with
the NetX NT-IPXB network controller.
This NetX™ X5-CFA thermostat will maintain the operation
settings during any type of power failure. When power is
restored the thermostat will return to the last MODE (Heat,
Cool, Auto, Off) and the Occupied setpoints. If the CLK
terminals are shorted at power up, the thermostat will operate
using the last Unoccupied setpoints.
High Balance Point
Default: 118˚F (48˚C). Select between 41˚F-118˚F (5˚C-48˚C).
The value is displayed on the main display. This will lock out the
auxiliary heat at the selected outdoor temperature.
A NOTE: Each thermostat connected to a network controller
must have its own unique address. This is adjustable from 1-99
but the NT-IPXB controller can only support 32 thermostats.
