Temperature Sensors, TEC, Standard

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 adj us tment

Applications

• Operating rooms

• Laboratories

• Isolation rooms, with pressurization as the

• Other difficult control spaces

• Executive suites and other high-profile areas

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

) 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.

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.

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

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).
