6. Light detection function

The T-Mini has a LDR: light-dependent resistor. This
light sensor ensures automatic switching between day
and night mode. If you want the T-Mini to remain in
operation for 24 hours (continuously), you can switch
off the light sensor. To do this, go through the
following steps:
1. Disconnect the power supply to the T-Mini.
2. Press and hold the PTK and plug the T-Mini into
the wall socket (keep the PTK pressed for a while).
3. The type and software version of the controller are
displayed on the screen.
4. Then, you will enter the main menu, including the
next options:
Fact. default

Press the PTK to confirm. You will return to the main
menu.
To return to the main screen, select >> HOME << and
press the PTK.

7. Calibration

The T-Mini comes with a unique CO
function that allows you to calibrate the device yourself
in case of large deviations.
Experience has shown that the SenseAir®sensor can
easily function for two years without calibration. The
sensor is calibrated at the factory with the highest
calibration
