Series 2000 (Interactive) Room
Temperature Sensors, TEC, Standard
Design and Semi-Flush Mount
Item Number 129-363, Rev. DAPage 1 of 3
Overview
For high-end Terminal Equipment Controller (TEC)
applications, these sensors allow users to view and
adjust points in the controller using the sensor buttons
and digital display.
A user-programmable display allows the simultaneous
monitoring of the temperature, a user-selected point
and day/night operation status.
Features
•User-programmable two-line liquid crystal
display
•Simultaneous display of temperature, a user-
selected point, and day/night operation status
•Backward compatibility with all TECs, including
PTECs.
•Hardware-protected security
•Standard RJ-11 terminated cable
•No separate power source requirement
•Digital (error-free) setpoint adjustment

Normal
•In normal operation, no passkey or laptop is
connected.
•The sensor may be set to display the
temperature and a second important point for
the user to monitor, called the "critical" point
(such as setpoint, airflow or fan speed).
•Day operation only: Setpoints may be viewed
and adjusted in 1° increments, using the
and keys.
•The sensor displays a sun ( ) or moon ( )
indicating whether it is in day or night
operation.
•In night operation, the override button
switches the TEC to day operation for the
length of time preset in the TEC.
Passkey
Insert the passkey in the sensor MMI port to:
•View controller point numbers, descriptions,
values, units and status.
•Change or command controller point values.
•Set up the following display options:
−Turn the temperature (TEMP) display on or
off.
−Select a critical point to display, if desired.
−Select units of measure—English or
metric.
Figure 2. Inserting the Passkey.
NOTE: The Semi-Flush Mount Sensor MMI port can
only be accessed after the front housing is
removed.
Laptop
To communicate with the TEC using Datamate Base,
Datamate Advanced, or Controller Interface Software
(CIS), connect a computer-compatible cable (see
Accessories) from a laptop to the sensor MMI port at
the bottom of the sensor. This puts the sensor in laptop
mode, which deactivates all buttons and freezes or
blanks the display. In this mode, the controller
communicates only with the laptop.
Considerations
Point 00 (SETUP): The sensors reserve Point 00
(SETUP) for display setup mode, but only the sensor
recognizes this point. It does not exist in the TEC
database.
At the operator's terminal, Point 13 on the TEC always
reads priority OVRD because the room sensor is
commanding the setpoint. This is normal and cannot
be changed if Point 14 is set to Y.
Point 1 (ADDRESS) and Point 2 (APPLICATION)
cannot be changed.
Display Messages
Message
Meaning
ERROR
NO COM
Communication with the controller is lost.
-F, #F, °F
If one of these three symbols displays, a
point has failed.
LOADING
PT# [xx]
The sensor is automatically loading the
point database numbers from the controller,
and displaying them as they load. This
happens: (1) the first time it is connected to
the TEC, and (2) when it is connected to
the TEC with another application.
PASS KEY
ACCEPTED
The passkey has been inserted in the MMI
port and accepted as valid.
#
Point value has been overridden by
operator.
*
TEC initial point value differs from its
factory default value.
Specifications
A 10K ohm thermistor is used to detect temperature.
The effective sensing and setpoint range is 55°F to
95°F (13°C to 35°C).
Operating Instructions
Setpoint (Day Operation Only)
1. Remove passkey (if present) from MMI port.
2. To view the setpoint screen: Press or .
3. To change the setpoint: Press or .
4. To cancel changes: Press .
