While not entirely home theater related, I am wondering if one of you has some knowledge involving relays.


I am trying to use a thermostat to trigger a separate AC circuit. Thermostats output a 24v AC signal to heating/cooling systems. Instead of a heating and cooling system, I want the thermostat to trigger a relay which then switches on and off the AC circuit.


So to clarify:


thermostat (24v AC) -> relay -> AC circuit (120V AC)


I need to know what kind of relay I should buy. I am looking at this one:

However, will a 24v AC switch activate this 125VAC relay?


I have done a lot of reading on this and I feel like I am really close to knowing how to do this, but I need some input. I know a lot of you are very knowledgeable about these kinds of things. The end goal is cooling a server rack for my home theater

How about one of these:




Attic Fan Thermostat....about $20 at HD, and is straight 120VAC trigger. I use it for equipment closet cooling, as have a few others on the forum.


Cheers,
