It looks like you're wired correctly but that behavior is wrong. Are you checking continuity of the relay or are you only checking voltage at the receptacle? What are your programming parameters? F1, F2, F3 & F4

I've checked voltage across the different ports, as well as continuity. Should the heating/cooling relays remain open with no power? I would think they would open up. Hopefully its a function parameter setting. I set F1 to 5, F2 to 1, F3 to 3, F4 to 0.

I believe you should get an open circuit between 7&8 and 5&6, when the unit is powered off. Disconnect your receptacle wiring and check. Your parameters look good. When the probe measures >= F1 + F2 AND it's been F3 minutes since the last ON time, 7&8 should have continuity until the temperature drops to F1. When the probe measures <= F1-F2, 5&6 should have continuity until the temperature rises to F1.

The cooling & heating lights are steady in cooling & heating mode. The cooling light blinks while the delay-on is timing out.

If this doesn't work for you then you may have a stuck relay. Did you happen to mis-wire the unit at any time?

The unit was never mis-wired to my knowledge. Seems like the relays are stuck or something since when powered off 5-6 7-8 remain closed. I'm approaching my wit's end and I've wasted enough of humanities time on this one today, will let it go and reassess tomorrow. Thanks for all the suggestions.

Has anyone ever had their controller turn itself back on after a power outage?

Yes. An awesome feature.

I should rephrase... It was off and the power went out. When it came back on the controller turned on.

Damn this is a long A$$ thread...
However, I ordered an STC-1000 so I better build one of these too. Maybe in the 10 days it takes to get it, I might get through all of these posts!

Never seen that happen, but just build a switch into the enclosure if it really bugs you.

I seem to be cursed with USPS. After having my first controller get lost in the mail, the second appears to either be lost or stuck in customs. Ordered 6/25, processed through the LA sort facility on July 3rd, an no tracking updates since. :/
