Simple manual for the extractor at Naturinstituttet

There are four buttons. The first from left shows "the book", "arrow down", "arrow up", and "enter"

Each time you change anything with the arrows please wait till the display flashes once (saying "stored")

 - it says: "rec.no"  here you can set the program number you want to overwrite with the arrows.

Use "enter"

 - it says: "T.REMN" ( time remaining) if there is a program stored it shows the hours and minutes of the actual program.

Use "enter"

- it says: "TSP.1"  (Target SetPoint no. 1) set the temperature you want with the arrows.

Use "enter"

-it says: "RMP.1" (RaMP no. 1). Beware here you may do wrongly!   This one shows the time of temperature, in deg., raising or falling, per minute!

Normally I recommend this one to be not more than 1.00  (30 deg. = half an hour)

Use "enter"

-it says: "DWEL.1" (hold the temp) keeps the temp. shown in hours, use the arrows.

Use "enter"

-it says: "TSP.2"  it is the same story as above with setting setpoints, ramp and time holding the temperature, -  2, 3, and 4.

Use "enter"

-it says: "STORE" and "done" when using the arrows you can set the program number you want or just wait a second until  the display blinks once. Then it shows  "done" and you have made a program!

Use "enter"

-it says: "OFF" and shows the actual temperature.

If you open the extractor while running a program, it goes in stand-by mode and resumes the programme when you close again [passer det - Erling mente han havde lavet denne funktion]

If you use the green button beside the controller you start the most recent  programme and the controller displays "Timer running" and the actual programmed temperature (setpoint) "OP1" is blinking, showing when the heating element power is on. The first two or three programme times a new program is running the controller is "Learning" how to reach the setpoints accurately and after four times you can trust the program within 0.25 deg. and this is reproducible if the samples have the same properties (humidity, insulation, sample height etc.).
