how did you do a 15min delay...I thought you could only choose 1,2, or 3 min?

I just double checked. The F3 setting is a range from 0 - 10 minutes. I have mine set at 10 minutes.

Greetings all - I'm about to start building my first Kegerator (Keezer actually) and this temperature controller looks perfect since it is only 30 bucks shipped. My only concern is the max amperage rating of 10 amps at 220 volts. Is that a high enough rating to switch a Freezer compressor? I'm not sure how much amperage a freezer draws, but I do know that 10 amps at 110 volts is half as much wattage as 10 amps at 220 volts. I'm not sure if that matters, but if anyone could give some insight as to whether these aquarium temperature controllers can handle a freezer, I'd appreciate it.

check the current rating on your freezer...if it's less than 10 amps, you should be ok. The starting current of a compressor is going to be high, but it shouldn't be enough to fry your contacts.

again (this was covered a few pages back) wattage has nothing to do with relay contact ratings...only current and voltage. Don't exceed them and you'll be fine.

Maybe this is showing my ignorance...but my freezer says current = 1.70. Does anyone know what that equates to for the controller?

My guess is amperage. Again it's a guess, but all other ratings would be much higher.

I'm not sure of your question...if the current is 1.7 amps then you're ok.

I think you are right. Initially I just thought that 1.7 amps seemed too low.
