Variable-speed timer switch

[LurfysMa]

We have one of those whole house fans. It works great. The only problem is that it is very noisy. It does have a variable-speed control (rheostat?) so that we can turn it on at various speeds from high to low.

What it doesn't have is a timer that will allow us to set it to run for a couple of hours and then shut off. In the summer, we often need it to run for awhile after we have gone to sleep, but not all night.

I went to the local electric store and asked if anyone makes a combination variable-speed and times switch the guy said no. I know that I can wire a timer switch in series with the variable-speed switch, but then I need to cut another hole in the wall.

Does anyone know where I might find a combination switch that will allow me to set the speed and also a timer for up to, say, 4 hours?

I tried Google for variable-speed and timer and switch, but I got either timers or variable speed switches, not both.

Thanks

Never saw one, but try Graingers or a greenhouse supply.

this handles up to a 1hp motor for $31.25 at:

That switch will turn the motor one and off (up to 36 times each day), but I did not see any variable speed capability.

X 10 will do all that and more, commonly available probably still at radio shack although they are converting to toy stores:(

turn on lights all thru home, dim them, work by timer and also by wireless remote controls

Is X10 stable and reliable now? I looked into it briefly a number of years ago (hmmmm, maybe 15?) and it seemed to have a lot of problems.

Each "unit" (light switch, etc.) has an address or ID and digital signals are sent over the house wiring, right?

I would need to buy an X10 switch for each device (light, fan, etc.) that I want to control, right?

Then I need a controller, right? Is this a stand-alone unit or can I buy software for a PC? If so, does the PC need to be dedicated to the X10 system?

I see several web sites:

Any that are better than others?

The bes ng is comp.home.automation, right?

Thanks
