Design A Motorized Slide Control

Design A Motorized Slide Control

PostBy: Devil505 On: Mon Oct 27, 2008 6:38 am

I'm looking for ideas on how I could bolt something to my ash door that would allow me to electrically control the slide air control on my Harman TLC2000 so that I could control it with a thermostat. The slide control has a full range of about 4" but must be able to make very fine movements of around 1/4" to work effectively. (It's in a finished room & must be able to pass the "Wife Test" visually! :lol:

Some type of stepper motor, screw actuators, etc, probably have to hook to a PLC or control system so it can send a signal to open or close....
Don't that have those temperature springs for dampers, maybe you could rig one up somehow....

You looking to run it from remote control so you don't have to get up out of your chair? Sound's like a Democrat thing to me :P

Devil, I told you how to do that last year. Not in increments, though ... open or closed ... works fine.

Forgot about that Dallas. This control looks like it may work. (did you make it yourself or buy it?

You can't make fine adjustments with it?
Is it really useful or did you find doing it manually worked easier?

The damper motor is a Honeywell ... number is in that thread somewhere. The gray box in the back contains a 26v transformer and relay (home fabricated), but I don't think, it's needed. I think, the damper motor can be controlled directly with the 26v thermostat.

The unit works great with a programmable T-stat. The house is cooler at night, the heat comes up before I get out of bed and maintains through the day. What more could you ask for. Also, with the programmable T-stat, you can factor in the "lag of coal heating and cooling off".

It won't tend to the fire, though.

Edit: A 26v transformer needs to be incorporated into the system. But I don't think, a relay is required.

Sounds like you should just come out of the closet, admit you're a girlie man, and buy a stoker! :up:

Naw, this baby will still function when the power lines are lying on the ground :lol:

I took a closer look at Devil's picture and it looks like the only air your stove gets is through the "slot", where the control moves. As you notice on my stove, when the slide control moves, it opens a much larger aperture. I was looking at this aspect in regard to travel. The travel can be regulated with the position of a strap mounted to the wheel on the motor. The longer the strap setting the larger the diameter of the arc of the strap.

Do you actually find it useful?
think the strap/wheel mounting could be adjusted for very fine control...say 1/4" movement?

I find it very useful. .. a big time and comfort saver. This particular damper control can't be modulated .. moved in small increments. It's either, open or closed. I believe there are damper controls, which can be modulated, however they need reversing voltage to direct the motor to move ... one way or the other.

That may very well be, however I don't believe the Coal-Trol is designed to keep your house temperature where you would like it ... if you are burning a hand fired stove. Feel free to correct me, if I'm in error.
