Posted: Sat Jun 19, 2010 2:04 pm Post subject: OT: Temperature Control Relay

Hi all,

  

 Very off topic.   

  

 I am looking for a small 12 VDC temperature control relay.  I want to enable the relay at ~120 degrees F. and disable it at 100 degrees F.  The maximum relay capacity can be quite small (I can add a larger relay if required).

  

 My searches are overwhelmed with AC versions and very expensive versions.  This seems like something that should be available for about $10.

  

 Thanks very much!

  

 Jon

    What you're looking for (I think) is a thermostat

    that closes on temperature rise at 120 and does not

    open until the temperature falls below 100F.

   

    Here's a part for clothes dryers. 



      http://tinyurl.com/25ksfkq 



   It's SKU number is 39076 on this page



    http://tinyurl.com/2gy4tma



 [/b] My local washer repair parts store

  shows it as an LD120 for $5 net/$11 list.



  It's a single pole, double throw device

  so you can use it for open or close on

  temperature rise.

Hi Bob,  

   

Very, very close!    

   

This is to operate a pump that circulates solar heated water thru my hot tub.  What you found is functionally correct, my only additional requirement is that I can mount the sensor in water (in the solar tubes).  Since I am learning, it might be good for the set points to be adjustable.  However; I am after cheap so that is certainly not a requirement.  

   

Thanks!  

   

Jon

Jon;  

   

Assuming your circulation system is plastic pipe, can you put a short piece of thin wall metal (copper or aluminium) tube in the water loop at a convenient location and clamp the thermostat offered by Bob to its exterior wall??? The temperature differential through the tube wall would be insignificant and you would then have a readily accessible part which wouldn’t require breaking into the water system to replace or experiment with different values should your initial estimation require changes. If your loop system is already metal pipe, just clamp the thermostat offered to the tube wall. Wrapping the assembly in insulation would further ensure virtually no differential between the water temperature and the thermostat’s reading.
