Hi
Can you say how works the 4 buttons in pre-heated unid, also the four leds in the left of the display.
For what itīs used the left button "circle arrow" and the 2 button by the left. When i press arrow down and up the small display temperature it`s not changing and i think that the unit it`s a program mode o any else.
Best Regards.

On some Preheater it is used for adjustment just one potentiometer, on some others it is a programable control unit - both constructive alternatives doing actually the same job.
The control unit has 2 displays:
- big red display showing the REAL TEMPERATURE of the coil(heating element) inside
- smaller, green display - showing the Temperature of the coil - that you are setting
There are 4 buttons on the programmer: It is really verry easy and intuitive to work with them.
The buttons:
nr1 and nr2: up and down to increase / decrease the temperature THAT YOU WANT TO SET (SMALL GREEN DISPLAY)
nr3: <- BUTTON for setting with the up / down button the x1, or x10 or x100 degree units. A Green point will show you what are you selecting at each moment.
nr4: circle Button - is for programming / storing different temperatures of the Unit.
This Digital control unit is designed for industrial use/autamotion and can do a lot more of advanced programmable functions.
Since mostly the preheater is used to set up a 100 - 200 degree temperature - most people will never use this button, but when i have some spare time i will do a manual for this also.
