Installation; Connecting Controllers And Sensors; Connecting Additional Sensors Or Other Devices; Which Sensors Can Be Connected To The T-Nano - TechGrow T-Nano User Manual

1. Installation

1. Mount the CO sensor on the wall near the CO
2
source, with a minimum distance of 50 cm. It is
preferred not to place the sensor directly above the
CO source if it becomes very hot (CO
2
Mount the sensor at a height of +/- 1 meter above
the floor.
2. Do not place the sensor in the direct airflow of fans
as this may affect the measurements.
3. Connect the sensor(s) to the bottom of the T-Nano
with the supplied (UTP) cable(s).
4. Plug the CO source to the T-Nano.

5. Plug the plug of the T-Nano into a 230V socket.
6. Ready!

2. Connecting controllers and sensors

Most of TechGrow's controllers and sensors can be
interconnected to ensure an optimal user experience.
Interconnecting the controllers enables to control the
total climate with only one S-4 Sensor. Since each
device has 2 UTP ports, it is not only possible to
interconnect the devices, but also to connect a
Datalogger DL-1, for example.
Make sure that all controllers are equipped with mains
voltage, and check if the controllers are switched off
before you connect sensor(s) to prevent any
malfunctions. The sensor can be connected to any UTP
port.
The regular TechGrow sensors are comparable to the
sensors from the TechGrow Pro Series and can
therefore also be used for controllers from the Pro
Series.
3. Connecting additional sensors or
other devices
The T-Nano can measure the values of connected CO
RH and temperature sensors, and transmit the data to
the connected controller, provided it is linked to an S-4
Sensor. However, the T-Nano only regulates
the CO .
2
If you want to connect another sensor or device to the
T-Nano, first switch off the controller, wait a few
seconds, connect the sensor/device, and then reconnect
the controller to the power outlet.

4. Which sensors can be connected to
the T-Nano?
2
The minimum sensor required is a S-Eco CO
generator).
ATTENTION: NEVER connect two of the same type
2
of sensors to your controller! For example: a S-Eco
CO Sensor and a S-2 Sensor must not be connected
2
at the same time.

5. Automatic functions of the T-Nano

1. When it is dark, no CO
that the sensor can detect the light source directly.
2. If the CO
released.

6. Meaning LED

Between the two rotary knobs you see the "OK" LED,
which can indicate a number of things:
Green: there is sufficient CO
•
Red: the CO
•
Led is off (white) : the relay is turned off (off).
•

7. Operation of the T-Nano

If the CO

Over time, the CO
setpoint, the source is switched off.
