Any automotive parts store likea Kragen's will have crimp-on connectors, "blues" would be for 16-18 gauge wire with a tight
fit on 14 gauge wires. Always use stranded wire not solid with
"Stake-On" crimp connectors unless you crimp plus solder with
solid wire, this as a "get out of a problem case only".

A lot of fridges already have a relay like this installed but trying to find it and wiring to it may be a little difficult for the average brewer.

I love the way this controller looks and I am going to be using it to control my Keezer. What relay would you suggest and how would you connect it the controller? Also how would this affect the setting parameters?

This is a great thread. Thanks!

Edit:
Would the SYL-2342, be a better choice? It is able to handle 7A-10A depending on the voltage. It can be seen at (http://www.auberins.com/index.php?main_page=product_info&cPath=1&products_ id=1)

Only one PID control, but most cooling solutions can't take the pulsed power anyways, so it's not a huge deal.

I've looked in the literature for the Auber PID and I don't see it listing the Alarm rating for voltage. Maybe they are the same as the relay voltage?

I like the idea of using a PID to control a chest freezer - good for summer and then in the winter time, since it's in my unheated garage, let a small heater keep it to temp.

Cooling and heating would be nice in the shoulder seasons - as here in Montana you can get pretty cold at night, but be warm in the day.

So...
with that said, given the amp rating for the alarm output (I couldn't find a spec) would I be better off to try to put the freezer on the alarm output and the heater on the on/off relay? OR, can would it just be wise to put it all on an SSR?

Thank you for the right up. I actually just did this with my tet612!

Thanks for the write up. I will be sure to use this in the near future.

Great thread!

It would be great to get the details/pictures on how to wire to a SSR.

It can behave as a heater, you would have to use one of the alarm out puts though. Set the alarm to the coldest temp you want and when it gets to that point the output will turn on and fire up the heater. for these, the heater would have to be rated less than 360W if you are going to directly drive it.

Without going off topic on Jason's great write up i'm a big fan of using blue 16-18 gauge eye vs fork crimps if I can as they can't be pulled off a terminal screw. I went cheap using parts I already had collected, a digital Johnson triggers a Mars 32382 timer preventing compressor short cycling as well triggers a SSR. Mars 32391 collection of .5 to 8 minute delays also be used. This in keeping the Johnson control happy without having compressor starting in rush current hammering it. http://www.appliancefactoryparts.com/applianceshvac/supco/hvac/Page17.html Wiring in a PID makes for a neat system I must add, the added cost is why I went with parts I already have.

I use the PID output to directly control the relatively low wattage heater I use, then the cooling is done through the alarm controlling an SSR. It's a small pain when you are changing temp. You have to change the Setpoint and the Alarm Low and Alarm High each time. It works great though and holds my temp when it's cold or hot out.

Rick your in a rather mild climate mostly warm to hot year round, i'd be surprised you need a heater at all.

We do love the mild climate here, but it get's chilly at night in the winter. If I'm trying to hold 65-68 and it's low 40s in the brewery/mancave/shop it needs a bit of heat. My mat is 25W, so it's not going to be enough heat for a ferm chamber where it gets 'cold' at night. This year, with the current weather, we could easily just leave the carboy out and the wort will average mid 60s.
