Example:
The CO2 set is set at 670 ppm.
The CO2 +/- is set at 40 ppm.
The current CO2 value in the room is for example
733 ppm, which is higher than the CO2 set, so
the CO2-source is switched off . The red lights are
now off .
The CO2 value now slowly drops to 670: nothing
happens.
Only if the value drops below CO2 set minus CO2
+/-, which in this case is at
670 – 40 = 630 , switches the CO2 source and the
lights will come on.
The CO2 value now rises and when the value of
670 is reached, the source will be switched off
again.
By adjusting the CO2 +/- a stable atmosphere can
be obtained.
Default factory settings are CO2 set at 700,
CO2 +/- at 50.
Meaning of the LEDs
Light detected: light indicator (under PTB)
OK: LED is green if the CO2 value is between
(set + hysteresis) and (set - hysteresis).
CO2: LEDs light up when CO2 is released.
(When CO2 heater / source are turned on)
Operating and adjusting the T-1 Pro:
All settings are done with the Push & Turn Button
(PTB). By pushing the button you will enter the
set-up menu. An arrow will appear on the left side
of the display =>.
When switching on the TechGrow T-1 Pro the
display will read:
TechGrow
T-1
Pro-Series
Software v. 2.X
The "System setting" screen is shown after a few
seconds:
System setting
CO2 calibration
You can read more about these menus further
on in the manual.
After a few seconds the start screen is shown:
CO2 =
456
CO2 set
700
CO2 +/-
50
Min
412
Max
The bottom line is interspersed with the "CO2
counter 00:12:25"
CO2 =
456
counter 00:12:25"
CO2 set
700
CO2 +/-
50
CO2 Counter 00:12:25
Here you can see all relevant data for the T-1 Pro
at a glance. The "CO2 counter" indicates how long
the CO2 relay has dosed.
Enter the menu by briefl y pushing the button:
=> TMP = 25.5 C
RH
= 32 %
CO2 = 539 ppm
This naturally only shows the values of connected
sensors.
Without connecting an S-2 or S-4, the CO2 value
will not be shown.
By rotating the PTB in the setup menu, you can
place the arrow in front of the various sensor
values. Press the PTB once to fi nd out more
about this specifi c sensor.
Only the min/max values are indicated for "TMP"
and "RH" sensors:
Line 1: The minimum measured value of the
connected sensor.
Line 2: The maximum measured value of the
connected sensor.
Line 3: The min/max values are reset back to the
current measured values of the connected sensor.
Line 4: << BACK <<
These measurements will not be saved during
power outages.
For CO2, more information is provided:
=> CO2 set

Here you can set the set-point and hysteresis for
the desired CO2 concentration.
