Hi All,
I have a Scania drawer fridge that has the Secop bd35 compressor and 101N210 controller - this bit works on 12 & 24v (checked by connecting C & T) it runs and gets cold.
It has a red electronic controller that plugs into the Secop controller terminals and is used for On/Off temp control & tilt control, but Only works on 24v and not 12v (not designed for 12V?)
The red controller appears similar to the Isotherm red controller but appears more basic - link Red Electronic Control Unit for refrigerator SCANIA 1894994, 2409029 - P.U.H. HESTA
the top 4 terminals go to the thermistor & on/off switch - this controls the IRF2807 and allows the earth side to connect
bottom 2 terminals go to the tilt sensor - open/closed circuit
Fan=fan
- & + 24v only - what I would like is to know if the circuit can be changed to allow 12v as well - as it is a drawer fridge it would allow me to connect to my car or use as a camping fridge & control it from inside the fridge drawer (ie front), instead of having to buy a temp controller of ebay & mounting (on back) of fridge where accessibility is poor & wiring in the thermistor to it.
I don't know too much about circuits
let me know if better pics/info are needed & thanks in advance
original module, rear spade terminals push onto the Secop controller.

note the 5 female pinout bottom rh is not used - suspect for programming?
