window ac timer question
i have a window ac that i want to turn on at a certain time to cool my
apartment before I get home from work, but can't get it to work with the digital time I bought from home depot. it doesn't turn on the unit when the timer turns on. how can i accomplish this? thanks in advance, TB |

Does it come on? If not, either the controls aren't set correctly, or the unit is one that requires a button to be pushed *after* power is applied. If it's the latter, I think you're out of luck. If the unit comes on when you plug it in, but *not* with the timer, then I'd guess the timer is insufficient to the load of the a/c. Check the amps or watts ratings of the timer. A/C units draw a lot of power; if there isn't a watts or amps rating marked on it, assume it's 15 Amps or at least 1200 Watts, which is the most you can draw from a normal household circuit. Your timer should be rated for that. However, you may find that setting the unit to run all day, but at a low setting (ie, not very cold, and low fan speed) keeps the room comfy and uses less power than having it come on full blast just before you get home. At least that's the advice that came with my a/c unit a couple of years ago. It's an "efficient" model that simply doesn't have a "full blast" mode. Many new a/c units have digital timers built in, but I'm sure you'd prefer to use the one that's already paid for. Chip C Toronto (where it's way too early to worry about a/c) |

If it's the latter, I think you're out of luck. this is a unit that require me to push a power button after it is plugged in. it has a digital front panel interface.

Your timer should be rated for that. my timer is rated for 15A, but i don't think it's the timer causing the trouble. Many new a/c units have digital timers built in, but I'm sure you'd prefer to use the one that's already paid for. this one does have a digital timer built in, but the way it works is that you have to turn the unit on, then can choose a number 1-12 (hours) that will keep it on for that long; whichever you choose. the thing is that you have to physically be there to turn it on before you can set the timer which doesn't work in this application. either that or i don't understand the timer. it's like a Sleep timer on a radio... |
