aquastat question.

[leaddog]

I just put in an aquastat to control a motorized valve and used what I had. I have three used ones so I thought I was in good shape. Well When I got every thing installed I realized That all of them open on temp rise. Can I just buy a microsw. that will close on temp rise or do I have to use a relay or do I have to get another aquastat? I'm trying to get by cheap but I might have to bite the bullet. I'd rather recycle.

Your best bet is an SPDT switched aquastat. I don't know the model numbers offhand, but they go both ways. There are some on Ebay on a regular basis, usually for $10-$20 (new) compared to $60 or $70 retail. You might want to check the Honeywell website (or whatever) for the right model numbers.

The strap-on SPDT switching Honeywell that I use is L6006C 1018.

The only eBay listing I found was for $70.35 (little pricey)

The deals I was talking about would be found in the actual auctions. You have to watch them for awhile until the one you want comes up. Then, as I said, you can usually get them for around $20 or less.

The prices down below are closer to actual retail.

Problem solved. Stopped at my local elect. supply and picked up a new sw for $8.53. It's a SPDT sw. it will work both ways. I was surprised as it was sure it would cost at least $25.
Thanks
