TechGrow T-Mini Handbuch Seite 13

1. Installation
1. Mount the T-Mini on the wall near the CO
with a minimum distance of 50 cm.
2. It is preferred not to place the T-Mini directly
above the CO source if it becomes very hot (CO
2
generator).
3. You should mount the T-Mini at a height of +/- 1
meter above the floor.
4.
Mount the T-Mini on the wall with the supplied
mounting kit.
5. Plug the CO source to the T-Mini.

6. Plug the plug of the T-Mini into a 230V socket.
7. Ready!
2. Automatic functions
1. The illumination of the display goes out
automatically after 60 seconds. Only when you
press or turn the Push-and-Turn-Knob (PTK) the
backlight switches on again.
2. Automatic switching between day and night mode.
3. If it is dark, no CO is released. So make sure that
2
the sensor can detect the light source directly.
4. Performs a measurement every second.
3. Operation of the T-Mini
If the CO level in the room drops below the set value
2
(setpoint minus hysteresis), the CO
on. Over time the CO value rises and when it exceeds
2
the CO setpoint, the source is switched off again.
2
Example
The CO setpoint is 670 ppm.
2
The CO hysteresis +/- is at 40 ppm.
2
For example, the current CO
which is higher than the CO
off. The red light is off.
The CO level now slowly decreases to 670: there is no
2
action yet. Only when the value drops below the CO
setpoint minus CO hysteresis, that is at 670 - 40 = 630,
2
the CO source switches on. The red light comes on.
2
Now, the CO level rises and when the setpoint (670
2
ppm) is exceeded, the CO
again and the green LED comes on.
By playing with the settings of the CO
stable atmosphere can be reached.

5. Control and set up
You can set the T-Mini with just one Push-and-Turn-
Knob (PTK). When the T-Mini is switched on, the
display shows:

After a few seconds the main screen appears. Here you
can read the actual values of CO

5.1 Set setpoint
You are in the main screen. Push the PTK for at least 5
seconds to enter the next screen:
CO2 set 700
Hyst.
Turn the PTK and select "CO2 set 700". Press the PTK.
=> CO2 set 700
Hyst.
Turn the PTK to select the setpoint desired.
Press the PTK to confirm or wait 3 seconds for
2
automatic confirmation. After a few seconds you will
return to the main screen.
5.2 Set hysteresis
You are in the main screen. Push the PTK for at least 5
seconds to enter the next screen:
