View Full Version : Need help with x-10 module for my chiller
06/22/2005, 06:15 PM
I have an AC controller. I am trying to have the x-10 controlle my 1hp chiller. When I hook it up it blows the x-10 module. I know some people are doing what I am doing with success with controlling there chiller with an AC not sure if I am using the wrong module or not. Anyone know how I can do this.

1 hp is to much draw. I believe the x-10 is good for 1/3 hp
What is the amp draw on start-up of the chiller?
What is the amp rating of the x-10 device?

im not sure how can I find out

What is make/model of chiller you are using?

There should be a tag/name plate with all the info on it. Sometimes on the back, sometimes on the bottom, but it should be there. It will list voltage, cycles, either watts or amps, refrigerant type, mfg, etc...

You will need to get a 120V relay that can handle the amp draw of the chiller. Connect the common terminals of the relay to the power source, and then connect the normally open terminals to the chiller. Connect the coil wires on the relay to the x-10 module.
I have mine hooked up this way. Remember to connect the ground wire on the chiller to the power source ground.

Acro steve do you have a drawing that you could send me. Where can I get a 120v relay?

Won't a heavy duty X-10 wall receptacle work for you? Those things can switch 15 amps.

never seen one around me

Have a look: X10.com (http://www.x10.com/automation/sr227_s.html)
I think you can get them at Radio Shack in the U.S. Radio Shack in Canada is now called the Source and no longer carries them. They are also available on ebay.

My chiller is 15.8 amps

I do not have a diagram, but you will need a double pole relay.
Take an extention cord and cut off the end that you plugh things into. Then hook those two wires to the coil terminals on the relay. You will then plug this into the x10 module, just like a light bulb for example.
Now, when the x10 comes on, the relay will activate.
The relay will most likely have 3 different types of remaining terminals; common, normally open, and normally closed. You will be using a pair of the 1st two types.
Cut the plug off of the AC unit while leaving some wire to work with. Strip it back and hook the black wire to one of the common terminals and the white wire to the other. Leave the green ground a little long and not connected yet.
Then cut the plug end off of the AC cord and connect the black wire and white wire to the normally open terminals while matching them up to the wires on the common terminals. White to white and black to black.
Or you can just cut both ends off of an extention cord and use them on the relay. You could then plug the ac unit into the plug on the relay and not have to cut the cord on the ac.
It's a little early, and I am a little short on time, so forgive the slight "skatter" in the procedure.

This is one place to get the relay.
10 amp relays are common. Higher amperage relays are more industrial.

Which relay do I need to get, do you have a way I could call you about this

The one in the link will do the job.

Why dont you just hardwire it to a DC4HD? I am sure that will handle the load.
