CAUTION
Electrostatic discharge can aect electronic
components. Take precautions during unit
installation and service to protect the unit’s
electronic controls. Precautions will help
to avoid control exposure to electrostatic
discharge by putting the unit, the control
and the technician at the same electrostatic
potential. Neutralize electrostatic charge by
touching hand and all tools on an unpainted
unit surface before performing any service
procedure.
IMPORTANT
Improper installation, adjustment, alteration,
service or maintenance can cause personal
injury, loss of life, or damage to property.
Installation and service must be performed by
a licensed professional installer (or equivalent)
or a service agency.

Overview
The wireless system employs the following
components:
M4/W4 Wireless Gateway System:
• Plenum-rated Bluetooth Low Energy (BLE)
antenna which will assist in boosting the sig-
nal from to Lennox CORE Unit Controller to:
»CORE Service App
»Wireless room sensors (wireless
mode)
»Wireless repeaters
• Ecient design allows for use in vertical and
horizontal applications
• Return air mounted antenna reduces signal
loss from roof and connected to gateway sys-
tem via coax cable.
Wireless Repeater (21L09)
• Used to “repeat” signal to sensors
• Increases eective range
• Up to ve repeaters can be used per rooftop
unit
• Powered by external 24VAC only
• Used in wireless application only
• Locking captive screw
Wireless Temperature / Relative Humidity
Sensor (21L07)
• TMP / RH / After hours override
• Unit powered by either 24VAC or four AA bat-
teries. Batteries provided but not installed.
Greater than two year battery life using AA
Lithium batteries.
NOTE: Please allow for a 45 minute adjustment
period on 24VAC powered sensors on
temperature readings
NOTE: Battery life of greater than two years is
subject to the sensor operating under
good signal coverage. If signal is weak or
the RTU is o for long periods the signal
strength LED will be on and the battery
will be depleted
• Wireless or S-BUS
• Locking captive screw
• Up to ve sensors can be used per rooftop
unit

Lennox®CORE Service Application Used for
adding Sensors and Repeaters)
• Connects to the Lennox®CORE Unit Control-
ler via the wireless gateway (W4)
• Pairs with a simple button press (requires
physical access)
• Used for installation of wireless sensors
and repeaters, service, and maintenance of
Model L rooftop units

NOTE: Changed switch settings only take af-
fect after a sensor power reset. Remove
24VAC or battery power after switch set-
ting changes.
NOTE: Switch settings are 1 = ON and 0 = OFF
Example:
S1 switch 6 (MODE)
ON = 1 – STAND ALONE
OFF = 0 – NETWORK/BAS (DEFAULT)
NOTE: S2 switches 4 and 5 are for future use
and have not aect on sensor operations.

• Battery Power: When the wireless sensor is
powered by the included four AA Lithium bat-
teries the sensor has a typical operational life
of two years.
• Line Power: When the wireless sensor is
powered by external line power (24VAC).

S-Bus connections can be used with M1-8 (IMC),
M2, M3 and M4 Unit Controllers. The sensor can
be used in the following congurations:
• By itself with a controller (Wired Standalone)
• In a network with a Lennox Network Control
Panel (NCP)
• In a network with a third party BACnet Con-
troller – M3/M4 Unit Controllers ONLY.
Standalone operation is a consist of (1) Unit
Controller and (1) sensor without a building
automation system (BAS). See Figure 4. Wired
Standalone for wiring connection detail example.

NCP
The sensor can also function with a unit controller
with an NCP/L-Connection System. The 21L07 is
compatible in standalone or with an NCP with the
following unit controllers:
• M1-8
• M2
• M3
• M4
See Figure 5. NCP Wiring Conguration on page
8 for wiring connection detail example..

NOTE: The following S1 and S2 switches need
to be set before power is applied to the
sensor.
STAND ALONE AND S-BUS
SETTINGS
NETWORK/BAS AND S-BUS
SETTINGS
NOTE: S2 switches 4 and 5 are for future use
and have not aect on sensor operations.
1. Set S1 (switches 1 through 5) for S-BUS Ad-
dress to match the S-BUS address of the
RTU. In operation with an NCP, each RTU
must have a unique address.
NOTE: Lennox M3/M4 unit controllers use a de-
fault S-BUS address of 2. If the sensor
and unit controller are both congured
to use address 2, there is no need to go
through S-BUS setup to change the unit
S-BUS address.
2. Set S1 (switch 6) for Mode to the ON position
to enable STAND ALONE or OFF (factory de-
fault) for NETWORK/BAS.
3. Set S2 (switch 3) Operation Mode to ON, for
wired S-BUS mode.
4. Connect sensor and RTU controller using rec-
ommended wire (two conductor, twisted-pair,
shielded, 22AWG). See Figure 5. NCP Wiring
Conguration on page 8 for further details.
