STC 1000 "EE" error

[gobuchul]

Does a STC 1000 give an error if the relays aren't connected?

I have been making up a 2nd STC 1000 fridge controller.

I have done it before and the other one is working fine, so I think the wiring is fine.

I switched it on and got an "EE" error which, according the very poor manual, indicates a short circuit.

Checked everything and could see no problems but still got the error when powered up.

I took everything off and just powered up the controller, still get the error.

I am thinking it will have to go back.

check the sensor connections,
if you have a multimeter, disconnect the sensor and check the resistance of the sensor

I've checked the sensor resistance and it's fine.

This is the wiring, basically a shared neutral and then a live for the power and the 2 switched lives for the cooling and heating.



This is how it looks when all connected up



If anyone can see anything obvious that I'm missing I would appreciate it.

Although it's quite hard to see whats going on in the 2nd photo!

To be honest, it's not a drama, I got it off Amazon so it's painless getting a refund and I have ordered another!

You don't have the sensor connected.

You could do with Stuffing glands rather than just the grommets, you could pull the cables out too easy the way they are now. +1 to AnthonyUK

I tried it with sensor connected made no difference.

Not sure what a stuffing gland is?

The cables will have cable ties on them to help keep them in place once the thing is finished and working.

These are stuffing glands, much safer.
