Hi!
I got tired of the usual parafin window openers for greenhouses, and beacuase I already had a bounch of chain-motors/electric window openers, laying around, I got the great Idead, to make it electrical.
I ordered a 24v temperature controller on ebay, for $12, but i'm not sure I got the right type.
My chain-motors work like this:
24v are supplied on the 2 wires, until the chain are full out. The motor automatical stops there.
To close the window/retract the chain, you just have to switch +/-, so the motor runs backwards.
I have attatched a diagram on the temp. controller, and how it should be set up, but I ran into a problem with constant power on the motor, as you can see.
Does any of you have a suggestion, how I can avoid this? Or should I looke for another type of controller?
I already have a 220v, that have isolated "Cool" and "heat" outputs, but I can not find those with 24 volts.
Will I be able to do this, by adding som diodes, to rectify the current?
