New fridge thermostat wiring diagram - In photo d underneath you will see the impartial white twine coming out of the percent relay, which goes into the again of the connector box in photo c (no longer seen within the image) into the fridge, again out of the fridge (nevertheless white) to the connector which meets the white neutral twine of the wall plug cord at the lowest of image c. I’ve indicated this “detour” at the bottom of my proposed wiring diagram with a circle around a “??? as i don’t recognize where this white wire is going and for what purpose. Is it reasonable to connect this white cord after the “detour” to the the neutral cord popping out of the heating element just earlier than returning to the wall plug? Everybody have any thoughts what it is probably?.
Inside the refrigerator hacking guide terminals three and four of the 2 ssrs are labelled as floor and manipulate respectively. So i'm guessing which means those two wires are linked to the brewpi spark thru the digital outputs? If that is the case how exactly are those grounded? For the reason that spark board is powered thru usb from the raspberry b and that in turn only has a live and neutral strength deliver, how may want to this be grounded?.
The temp probes also have a ground cord and doesn’t the equal practice to them as properly? As an alternative have to i connect the floor wires at the temp probes within the refrigerator to the inexperienced wire from the fridge thermostat which is grounded at the steel frame of the refrigerator? (See photograph underneath of indoors fridge thermostat wiring).
Image b - below you could see the wall black plug twine (stay black and impartial white and ground inexperienced) coming up from the bottom of the picture to the connector that leads to the indoors fridge thermostat (stay black, neutral purple). Right here the pink cord (sheathed in white) coming from the thermostat modifications to blue after and ends in the compressor.
