INSTALLATION
1.
Fabricate a rectangular front plate opening with the following dimensions:
W45.5mm x H22 mm for TCM220 or W68.5mm x H33 mm for TCM320.
Use a spirit level to achieve horizontal alignment.
2.
Match opening with the module and then push gently on the front casing, not the LCD, until
the module locks into place.

cONNEcTION
Solder the currentless wires of the battery pack's (3 V/DC) power supply to the solder terminals
"VDD" (10) and "GND" (9).
Connect the module to a suitable keypad. For this, connect suitable connection wires to the
positive input of the keys "MIN/MAX" (6), "PLUS" (7) and "ALARM" (8), and connect the other
ends of the wires to the solder terminal "VDD key" (5).
For the LED, solder a connection wire from "VDD" (10) to the solder terminal "LED+" (11) and
from "GND" (9) to "LED–" (12).
For connection to a computer, connect "GND" (9) to the plug's earthing terminal, "DATA_OUT"
(17) to the data transmission terminal and "CLOCK" (18) to the data reception terminal.
OpERATION
If you have no keys connected to the module, you can make the settings by applying a
3 V/DC voltage to the solder terminals for a respective period of time.
•
By pressing any key following application of the voltage, the measurement interval for the
temperatures of both channels that is automatically set to 10 seconds will be shortened to
2 seconds.
•
To switch between Channel 1 (CH1) and Channel 2 (CH2), briefly press the "PLUS" key.
•
To display the stored minimum and maximum temperature of the selected channel, press
the "MIN/MAX" key. When you press and hold the "MIN/MAX" key for 3 seconds, the internal
MIN/MAX value is set to the actual temperature of the selected channel.
SETTING ThE ALARm
1.
Select the desired channel with the "PLUS" key.
2.
Press and hold the "ALARM" key for 3 seconds to enter the alarm setting mode.
3.
Press the "PLUS" key to set the lower temperature threshold. The temperature will be
increased in 1°C increments from -30ºC to 70ºC.
4.
Press the "ALARM" key to move on to the upper temperature threshold setting. Proceed as
with the lower temperature threshold.
5.
Press the "ALARM" key to exit the alarm settings. To exit the alarm setting mode immediately,
press the "MIN/MAX" key. The device will automatically exit the alarm setting mode when no
activity has been registered for 8 seconds.
6.
To display the lower/upper temperature threshold, briefly press the "ALARM" key. If the
alarm is activated, the buzzer alarm will sound and a small icon will appear on the LED's left
side to indicate what triggered the alarm. The respective alarm output (13, 14, 15 or 16) is
then set to high level (VCC).
