Quick Start Guide
Thermostats
TST thermostat has a measuring range for the ambient model from 0 to +50 °C.
For the duct model it would be from -20 to +80 °C and for the terminal block
model from -100 to +400 °C (depending on the connected Pt100 probe).
Symbols used
For your safety and in order to avoid any damage of the device,
please follow the procedure described in this document and read carefully the
notes preceded by the following symbol:
The following symbol will also be used in this document, please read carefully the information notes indicated after this symbol:
- Output 1 RCR relay 3 A / 230 Vac. NO (normally open): 5A / NC (normally closed): 3A / 240 Vac. Common mode voltage <30 Vac.
- Power supply 24 Vac/Vdc ±10%
- Consumption 3 VA
- Relay and alarm status Red LED in front and internal buzzer (70 dB at 10 cm)
- European directives 2014/30/EU EMC; 2014/35/EU Low Voltage; 2011/65/EU RoHS II; 2012/19/EU WEEE
- Electrical connection Terminal block for cables Ø0.05 to 2.5 mm2. Carried out according to the code of good practices
- PC communication USB-mini Din cable
Environment Air and neutral gases.
Connection of a Pt100 probe on terminal block:
- Switch
- Terminal block (only on model with terminal block)
- LCC-S software connection
- Alarm led
- Button for settings
- Relay terminal block
- Power supply terminal block
- Cable gland
NO: normally open
COM: common
NC: normally closed
- Set the hysteresis
The hysteresis only concerns the rising edge and the falling edge modes.
In rising edge mode, the hysteresis allows to the transmitter to stay in alarm when the measurement is between the threshold and the threshold minus the hysteresis.
Example: for a 70°C threshold and a 10°C hysteresis, the instrument will stay in alarm when the measurement will be between 70 and
60°C.
In falling edge mode, the hysteresis allows to the transmitter to stay in alarm when the measurement is between the threshold and thethreshold plus the hysteresis.
Example: for a 70°C threshold and a 10°C hysteresis, the instrument will stay in alarm when the measurement will be between 70 and
80°C.
The first digit blinks, set it by pressing the button briefly several times then press on the button more than 3 seconds to set the following digit.
Once the hysteresis is set, press the button more than 3 seconds to validate and set the time-delays.
• Set the time-delay 1 and the time-delay 2 (600 seconds maximum)
– In rising edge mode, the time-delay 1 corresponds to the time lag before the alarm goes off when the threshold has been reached. The
time-delay 2 corresponds to the time lag before the alarm stops when the measurement is lower than the threshold minus the hysteresis.
Setting procedure: “Time 1” for the time-delay 1 is displayed then the time in second. The first digit blinks, press briefly on the button
and scroll the figures. Press on the button more than 3 seconds to validate. Repeat the process until the last digit to set the time-delay 1
value (from 0 to 600 s) and validate . “Time 2” is displayed the time in second. Repeat the process to set the time-delay 2.
– In falling edge mode, the time-delay 1 corresponds to the time lag before the alarm goes off when the threshold has been reached. The
time-delay 2, corresponds to the time lag before the alarm stops when the measurement is lower than the threshold plus the hysteresis.
The setting procedure is the same as the rising edge procedure.
– In monitoring mode, the alarm of the transmitter goes off when the measurement is below the lower threshold and higher the high
threshold. The time-delay 1 corresponds to the time lag before the alarm goes off when the measurement is below the lower threshold
and higher the high threshold. The time-delay 2 corresponds to the time lag before the alarm stops when the measurement is between the
lower and higher thresholds.
The setting procedure is the same as the rising edge procedure.
The setting of time delays is done, the measurement is displayed.
Configuration via LCC-S software (optional)
The software allows to set the alarms, the thresholds, the relay action, the
hysteresis and the
time-delay of the device. • To access the configuration via software:
- Set the DIP switches as shown beside.
- Connect the cable of the LCC-S to the connection of the transmitter. • Please refer to the user manual of the LCC-S to make the configuration.
The configuration of the parameters can be done either with the DIP switch or
via software
(you can not combine both solutions). Switch off the sensor before settings
process.
Mounting
To mount the transmitter, mount the ABS plate on the wall
(drilling: Ø 6 mm, screws and pins are supplied).
Insert the transmitter on the fixing plate (see A on the drawing
beside). Rotate the housing in clockwise direction until you hear a
“click” which confirms that the transmitter is correctly installed.
Ambient model has not any fixing plate.
4 fixing holes are inside the back housing. Use them to
install the transmitter on the required location.
