It may not have enough current (amps) available to run a fogger, 24v solenoids generally need a small current to operate.
The price was right so its worth checking into.

Thanks for your response,The orbit transformer is rated at AC 26V 300mA and the controller utilizes a .75 amp fuse. All I know about the fogger is that it runs on AC 24v, so I ordered one. I will see how much current they draw when I get my hands on one, and keep you informed. Thanks again.

Just received the fogger, you are correct. It draws .82-.90 amps. Just a little too much for the controller fuse. Is there some kind of relay available that would allow this controller to operate 120 volt circuits. Maybe a radio shack part? I think it would be a great timer for fans, pumps, lights, heaters etc., if I could figure out a way to make it work.

Yes you can use a Solid State Relay to switch it on and off.

Probably any SPDT 24v coil relay would work (available at your nearest HVAC supply house). Good luck with the project.
