Here you can adjust any deviation in the display of the temperature measured by the plant temperature (PT) camera.
Since the controller intervenes in case of relatively small temperature differences, it is important that the room temperature
indicates the same value as the plant temperature camera. You can check whether the values correspond by hanging a
sheet of paper in the shade of the room. You can check whether there is a difference in the room temperature and the PT
camera by directing the PT camera toward the sheet of paper after approx. 20 minutes. (The sheet of paper adopts the
temperature of the room). You can adjust the value by pressing briey on the SET key and using the + and – keys.

The sensor that measures the RH% in the room can also be calibrated. Press the SET key and use the
+ and – keys to adjust the value.
High / Low
Here all high/low values of all connected sensors are displayed. Using the + and – keys, the values of the various
sensors can be displayed, including the time when the Maximum/Minimum Event has occurred.

CO2 high/low
H CO2 391p 13:15
L CO2 184p 13:13
The highest and lowest CO2 value including the time are displayed. The high/low values can be reset by pressing the
SET key in this screen and by using the + and – keys to select Reset > Yes.
The high / low values are always reset every day at 00: 00hr. By pressing SET, the time that it is reset is changed in
the menu from 00 to 23hr. It is also possible to set the reset OFF, in which case the high / low values will not be reset
until the user does it manually. The OFF function is between 00 and 23 hr in the menu.
Error/Events
The error/events screen shows the date and time that an event or error has occurred. Here you can read (for example)
whether dimming was carried out, because the temperature was exceeded. The log can store up to 10 events/errors.
If the log is full, the rst entry is overwritten. Pressing the SET key will erase the event/error log.
If the message PSU ..... V ! ! ! appears, the controller is connected to an
adapter with the incorrect voltage. The voltage must be 16 volts. Use the original adapter.
