trigger momentary switch/button via switch Answered
what i try to accomplish is very simple.
my Airconditioner has a Push button (momentary switch) to turn it off and on.
but the Thermostat brings permanent power it it want the A/C to be on.
i could make a simple delay setup for 1 sec. or so to trigger a relay but then i can't be sure its really on or of.
how can i ensure its turned on via an timer relay safely if the control wire has power ?
any recomentation on existing products or schematics ?
i can check the "real status" via other parts on the airconditioner easy .. i just need a way to ensure ON and OFF based on the command line is High or Low ..
any ideas ?
