hello,
i have a sharp AC/Dehumidifyer that cost me a lot of money. its nice
and quiet. but, i'd like to set it on a timer, so it only dehumidifys
when there's moisture in the air. unfortunately, you control the whole
unit from a remote. the remote turns it on and changes the modes
(between ac and dehumidify). i was just going to plug it into a
humidistat, but cycling power to the unit does not turn it on/off. ie:
when i unplug it, and then plug it back in, it starts in the off
position, until u turn it on with the remote.

i know this is vague and impossible to answer with out having the
design of the unit, but my question is: does and IR on/off switch
usually connect to an actual mechanical switch?

how can i find where the switch is? my ideas is that if i bypass the
switch, by connecting it permanently, then i can control the unit with
the power supply.

any ideas would be helpfull
thanks

If it's got a remote it's probably got a fairly complex internal
control system which you'd need to partially duplicate

Can you connect the humidistat to the remote-control?

Rig up a Rube Goldberg kloodge that mechanically pushes the "on/off"
button of the remote, and control the kloodge with the humidistat.

Have Fun!

Hack a new remote with a built in humidistat?
