Help with Temp control on LTH HO 1500 BEM/S

[chemist]

It is about the following fridge:

we recieved the same. On the display (third picture on the link), I have the following options when I press the i-button: t1, t2, thi, tlo, cnd, Loc

I have tried turning it on by holding he on/off button. It turns on and starts cooling (somehow always from above 30 degrees) down to 24-25 and then it stops, starts beeping, where I recieve a blinking "do" on the display.
I would like to set the fridge to 4 degrees and use it like that. (I think this one records a range of temperature changes if connected to a computer, but I dont need that) If anyone is familiar with this machine and its control, could you please tell me what to do? Or if anyone has a manual that they could send me, that would be also much appreciated.
Kind regards and a good day,
Chemist.

What you see is only the control panel. it is connected to a controler, take a chir and look at the model of the controler and panel and post them here, we will help you with the manual.

Hello chemi-cool,
Thanks for the quick reply.
the display belongs to an electronic board with the model LTH3RU-A which is connected to a thermostat with the model LAE LTH3C35E-B.
hope this helps.

Sbut i could not find that controller on the web, there are others that will help. meanwhile you can drop an email to Lae manufacturing for the manual, I'm sure they will be helpful.
