Turn on an air conditioner after a power failure?

[Cam]

Hey all,
I was wondering if you had some suggestions on where/how to buy/make a
device like one of those cute nodding ducks - but I only want it to nod
once.

I've got an air conditioner that does not power back on after a power
failure. And the control unit is powered from the condensor unit, so it
draws too much power to put the whole thing on UPS.

What I'd want is something to mount over the control panel, and when power
is first applied to it, it presses the ON button on the control panel.

Any thoughts?

Cheers
Cam

A solenoid and a timer.

Yes, one ... almost all refrigeration systems and heat pumps have a time
delay to prevent the compressor from restarting when the back pressure is
high. The delay is usually 5 to 15 minutes. Are you aware of this?

Thanks for that Charles.
No, I wasn't aware of that.
The unit definitely doesn't power back on at all - we checked with the
manufacturer.
But I guess this extends the requirements to include a timer after power on.

my does the same!

you could mount inside electronics a Ni-Cd baterry to power
electronics/microcontroller when power is off (this would prevent a
reset of a chip keeping the data inside IMHO ...
