Stc 1000 query

[Eccipoo]

Hi folks, I've just wired up my stc and I'm coming across a bit an annoying problem. Before I start, it is definitely wired up right, functions have all been set up to desired degrees, compressor time etc etc

The flashing light will not go off beside the cooling label. I've cooled the sensor to check if my 60w tubular Heater will come on.....no problem, stc does its job on that front

However, when it heats back up to the temp for the fridge to kick in? Nope, fridge doesn't turn on, and flashing light comes on.

Kept it on for 20 mins to see if it might be a compressor related type problem, even though I have that set for 3mins. No joy. Turned it off and back on, waited.....no joy

Any help appreciated.

There is a delay set to preserve the compressor getting shot on the fridge.
The flashing light besides the cooling means it's on the timer and waiting to cool.
Put stc probe in 60 degree water and it should come on straight away.

Yes, compressor time (F3) is set at 3mins and still not coming on

Can you hear it clicking? Could be a shot relay.
Pics of unit (some are only hearing it cooling not both)

and wiring you've done next pls (you may have blown the relay)

I can hear it clicking for the for the heater but not for the fridge

Changed the settings for the compressor to 1 minute now. First time the fridge came on this time.....for a split second.....then it switched off as did the stc....which now won't come back on....at all

Have you lost power to the STC now.

Does it smell inside?
Unplug it first!!
Is that a 110v version?

[Eccipoo]

No, I've plugged it in and out a few times and done exactly that, opened the housing and smelt around. No smells or signs of smoke

No sir, 220v

Dempsey you had some issues here with similar issues, dodgy brand?

I had 4 of them just blow. Have a surge protector on the fridge unit now and it's holding.
