Continued from first page.
Available in twelve models, MN-Sxxx series sensors
provide an integral analog-to-digital conversion for
elimination of sensor-to-controller noise effects and
wire resistance offset.
Using the digital wall sensor, the operator can monitor
performance and edit operational settings. MN-Sxxx
series sensors are suitable for direct-wall, 2 x 4
electrical box, 1/4 DIN electrical box, or surface box
mounting.
The MN-Sxxx series sensor measures room
conditions and transmits the information to the
controller via the S-Link. A single sensor is connected
directly to an application specific TAC I/A Series
MicroNet controller via low-cost, unshielded, twistedpair cable. The connection between the sensor and
controller is not polarity-sensitive.
A convenient connection to either a MicroNet
L
onWorks
®
or MicroNet BACnet network is provided
as an option with each sensor in the series. If the
LonWorks network wiring is connected to the sensor,
a PC running WorkPlace Tech Tool or a third party
Network Management Tool can be connected to the
network at the sensor. This feature allows convenient
access to the MicroNet L
onWorks network.
FEATURES
• Contemporary, low-profile packaging.
• Digital zone temperature indication (selectable for
0.1 or 1 degree display resolution of °F or °C).
• Self-compensating temperature conversions
remove the need to calibrate over time.
• Digital zone humidity indication (selectable for 0.1
or 1% RH display resolution).
• Long-life humidity sensing element with excellent
resistance to contamination and condensation.
• Pushbutton override capabilities allow occupants
to switch to timed occupied mode for after hours
operation.
• Displays selected system values such as
setpoints, outdoor air temperature, and operating
mode.
• Provides the ability to change operating modes.
• Directly connects to selected TAC I/A Series
MicroNet controllers via low-cost, unshielded,
twisted-pair cable, which provides both power
and communication.
• Separate wiring subbase and electronics.
onWorks network jack for convenient network
• L
access.
• S-Link jack for Pocket I/A access to the
connected controller.

MicroNet Sensors
COMMUNICATIONS
S-Link
Sensor Link (S-Link) communications wiring provides
power and communication interface to the
TAC I/A Series MicroNet sensor (MN-Sxxx series). It
uses two-wire, unshielded cable and is not polarity
sensitive. From some sensor models, the user can
view and adjust application parameters. Maximum
wire length allowed between a controller and the
TAC I/A Series MicroNet sensor is 200 ft. (61 m).
BACnet or LonWorks Network
The BACnet or L
onWorks network wiring can
be connected to the second set of terminals in
the sensor base. This optional connection allows
convenient access to the L
onWorks network at the
sensor.
