Re: (ET) Dan's 2/10A charger

I sorta agree with Paul about just using the Landis controller. I have two of the Landis units, but I also have a box full of old GE timers. But if you really want and/or need a timer, has anyone ever tried or considered a spring wound timer like those used to control whole house attic ventilation fans. They mount in a standard electrical box and some run as long as 12 hours. They would make a cleaner installation than the "plug it in the wall" type timers. And they don't need any elaborate wiring to install them. I think the OEM timer in our ET's went a little longer than 12 hours, but...
Another thought might be to use a spring wound 12 hour timer initially and wire up a Landis to kick in after that and keep things "charged up".
And another thought would be to let the OEM timer control a solid state relay, like the one Harry uses on his controller, to actually turn the charger on and off. 15 amps or better going through those rather flimsy contacts is just not a good idea. As long as the contacts haven't actually burned up and/or welded themselves together, the OEM timer can be taken apart and "worked on".

Guys don't replace the timer, buy a Landis controller
and keep the ET charged all the time.
The Landis replaces the timer and monitors the pack
voltage to keep the pack at 100% charge using the ET
charger.
I have had a Landis for 4 years and I always stay
charged.

I take it you mean "air conditioner TIMERS."

I've used one of these by rewiring it so that when
the switch turns off the load,
it also shuts off power to the timer motor.

I never thought to mangle the off trip.  I suppose
it work equally well, and
would probably be easier to do. However, if you
break something off, that's
most likely a permanent change.  Wiring changes are
usually reversible.
