TAC I/A Series

MicroNet Sensors

2

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.
