Honeywell TST-R, TST PRODUCT DATA

APPLICATION

Honeywell FEMA's TST and TST...R series thermostats
require adjustment (configuration and parameterization) in
only two modes (the basic mode and the expert mode) and
are suitable for the precision-adjustment and monitoring of
medium temperatures in the fields of plant construction,
fluidics, process technology, and pneumatics, as well as in
the monitoring and control of furnaces, heating units, and
process temperatures, as well as for applications in the
field of frost protection.

These thermostats provide sufficient accuracy (0.5% of the
final value) for measurement monitoring in many laboratory
applications. Models with built-on sensors for a tem­perature range of -50...+200 °C and models with an ex­ternal sensor for a temperature range of -50...+400 °C are
available. Customized PT1000 precision class-A sensors
can also be employed in the aforementioned temperature
ranges.

TST AND TST...-R SMARTTEMP ELECTRONIC THERMOSTATS

FUNCTION

The TST and TST...R Thermostats are screwed directly
into the pressure line or the boiler's (medium container's)
connection nozzle. Built-on or external PT1000 accuracy
class-A sensors are used to monitor gaseous media and
high-viscosity liquids. The sensor signal can be used for
both single/two-channel switching functions (with freely­configurable switch-point and reverse switch-point) and
analog signals (0...10 V and 4...20 mA).

As soon as the sensor is screwed into place and connected
with the power supply, the LCD display screen indicates
the temperature as a 4-digit digital value and as an analog
value (bar graph).

Two LED's provide information on the switching status of
the outputs and on the alarm status.

The thermostats are configured and parameterized using
the large rotary/push button. The user can move from
screen to screen and enter values and/or change con­figurations by rotating the button. Values and configurations
are confirmed and/or stored by pressing this button.

Parameterization and configuration are performed in only
two modes (the basic mode and the expert mode).

Basic Mode (Parameterization)

• Outputs 1 and 2: Adjustment of the switch-points (SP)
and reverse switch-points (RP).

• Switch ON/OFF delay of 0...3600 seconds.

• Adjustment of the lower (ZERO) and upper (FSO =

"full-scale output") reference values for limiting the
analog output signal to a defined temperature range.

• Setting of a filter value in a range of 0...95% (ATT).

• When locked, can be unlocked by entering a CODE.

Expert Mode (Configuration)

Output 1 (OUT1)

• Configurable as a maximum or minimum monitor.

• Configurable as a window monitor.

• Configurable as normally-open or normally-closed.

• Configurable as low-side/high-side switch or as push-

pull switch.

Output 2 (OUT2)

• Configurable as a maximum or minimum monitor.

• Configurable as a window monitor.

• Configurable as normally-open or normally-closed.

• Configurable as low-side/high-side switch or as push-

pull switch.

• Configurable as a warning output (max. 250 mA).

Analog Output (AOUT)

• Configurable as a 0...10 V / 10...0 V or 4...20 mA /

20...4 mA output (default setting: 0...10 V)

Additional Configuration

• Relay output (REL) configurable to be coupled with
OUT1, OUT2, or the warning output.

• Selection of the temperature units (°C or °F) in the
UNIT display.

• Data restorable using the REST command.

• Selection of a 4-digit locking code (0001 to 9999) in

the CODE display (0000 = no code).

• Simulation mode:

– Using the rotary/push button, the temperature can

– The outputs can (in part) switch alternately in

• The LCD display's backlighting can be switched from
"on continuously" ("LCD+" shown in display) to "turned
off when rotary/push button not operated for 30 sec"
("LCD-" shown in display).

• Electronic drag indicator (represented in the LCD
display by a dotted arrow) for indicating the max./min.
temperature. After pressing the rotary/push button, the
user can (in the EDIT mode) read off the elapsed time
(in hours; resolution: 0.01 h) between the event and
the present time.

Process Connections

The device is connected to the temperature-side via a
immersion sensor with a G1/2" threaded connection; in the
case of external sensors, via an M8 plug (available as an
accessory) on the device's sensor-side.

SmartTemp thermostats with a temperature range of

-50...+50°C are equipped with built-on PT1000 class-A

temperature sensors. Two different lengths are available
(100 mm and 250 mm).

To improve their thermal insulation, the built-on sensors for
a temperature range of -50...+200°C are designed as neck­tube sensors.

All sensors for a temperature range of -50...+400°C are
designed as external sensors and are attached to the
evaluation electronics using an M8 plug (available as an
accessory).

A universal mounting kit is available as an accessory for
screwing the device either directly to the wall or installing it
to a C rail.

order to test the installation's reaction time in the
range of from 4 times per second to once every 16
seconds (corresponding to 0...100%).
