infra red timer

Hi,

All my air conditioners only allow me to set up on ON/OFF time. This means that I cannot set it up, for instance to turn from 2am to 3am and from 5am to 6am, for example.

Is there any infrared timer that would send the on/off command to the air conditioner and that could store more than one command? Obviously, it would have to be pointing to the aircon but that is easy. I looked on ebay and google and could not find it.

Or any other suggestion?

Thanks.

Have a look alt lirc. Then you can control it with a computer.

Does your air conditioner plug into a 15A receptacle? Can you get a
timeclock with multiple time/program setting available (such as by NOMA,
Tork, and many others), plug the air conditioner into that, and just the
leave the air conditioner settings such that it will always run when it has
power?

There are MANY different types of air conditioners. Might help if you
gave information as to what what Brand/Model and type air conditioner
you have!

For example there are whole house units with an inside unit, outside
unit, and a wired thermostat.

Or there are window air conditioners with a mechanical on/off switch.

Also there are window air conditioners which come with an IR remote
control. Is this what you have?

Hi Bill,

I have 4 aircons. An Haier, a Mitsubishi, a Samsung and a retail branded. All wall units, inside and outside units.

The Mitusbishi allows me to set up 1 on time and 1 off time

the other 3 only allow me to set up a count down timer, such as: turn off/on in xx hours.

None of them turn on automatically after a power surge, so putting a timer in the plug, will not work..

Thanks.

If they come with a hand held "remote control", it would be *possible*
to design or possibly purchase an already made "universal remote" which
could record the on/off IR signals from those remotes. Then place that
remote on a shelf pointed at the A/C unit. And it would send on/off
signals based on an internal timer on that remote device.

Search google.com for the words...
home automation

....then poke around some of those websites like smarthome.com, see if
they have anything like that.

Do-it-yourself "capturing" of the IR codes and then programming a
microcontroller to send those codes is an advanced software engineering
project. Many people who spend all their time tinkering with electronics
would have a difficult, if not impossible, time doing such a project.

If the "outside units" have separate power, you could use something like
a 7 day 240 volt "water heater timer" to interrupt power to just the
outside unit. Then power would remain to the inside unit.

Or a bit more advanced would be to get wiring diagrams of each unit.
Then install contactors (relays) which would shut off power going to the
fans/compressors of each unit. Then each unit's electronics would remain
powered up, but could only activate the fans/compressors when those
contactors were in an "on mode" (set by a timer).

But if the unit's electronics are "smart" doing the above might cause
them to go into an "error mode". And of course this would void any
warranties.

Thanks Bill.
That was what I was thinking when I post this topic.

Unfortunately, I cannot find a remote with timer.

Thanks anyway.
