Title: Wiring a Love Temp Switch
Post by: ndcube on November 14, 2009, 07:42:57 PM
I got my TS2 and am going to wire it up soon.

Is it best to break hot or neutral thru the switch?

Hot side my friend... Think of it as nothing more than a fancy light switch.

Thanks.

One more question...  Does it matter which way you wire the thermister?  I assume the switch is just measuring the resistence.  There is a blue and a brown wire.  I can't remember if those things are one way or not.

You are correct my friend... It will not matter. What switch do you have exactly? And I hope you are not going off my old Brutus prints! (I am sure you are not) I had the early 2008 model. They changed it VERY shortly after the article came out and the later models are wired differently. I have other newer diagrams if you need that other nice folks have done on other forums...

Nope.  Just trying to go by the instructions and my memory from electronics lab 10 years ago.

I got the TS2.  I tried for the TS3 but it's back ordered until mid-January and I didn't want to wait that long.

A diagram would be good.  I just noticed it doesn't specify the order for neutral/hot on the power supply. I'm assuming it wouldn't matter...?

I am pretty slow! So before I electrocute you, I better ask for you to explain this for me! :)

I'll dig up some better diagrams. Gawd knows, the ones that come with the unit are hilarious!

I'm usually too fast.  I need to learn some patience and slow down.

I took a closer look.  Looks like 7 is neutral and 8 is hot.  That look right?

Edit:  I have the 110VAC model.

Here is a nice diagram someone on HBT had done. Kudos to them!

This should help...

Or you can go without the jumper and wire it this way...

I wouldn't wire the compressor directly to the controller and switch it with the internal relay. I'd use the control as a master to drive a slave relay. The internal one is only rated at 5A inductive and a larger freezer or fridge could push that.

I got an 8.8 cubic foot freezer it says 5.0 Amp on the panel.  Do all freezer compressors use an inductive load?

Thanks.  That's how I did it.  I tested it out on my outlet tester and everything lights up ok.

A compressor (or any motor) is an inductive load.
