Hi David,

I’m using a JDS Time Commander Plus. I have the main unit and two slaves. I
wouldn’t recommend using this system, however. About once a month, it locks
up. When I first encountered the problem, JDS said it was my program (it ran
on the Time Commander). I eliminated their excuse when I started running
ECS. Now, it (the Time Commander, not ECS) still freezes every month or so.
In fact, I’ve proven that the Time Commander will lock up about once a month
without running any loaded programs or device definitions. JDS still refuses
to admit their BIOS is defective.

Anyway, I want to move to a new ADICON CPU-XA or Ocelot, but haven’t taken
the plunge yet.

As far as the HVAC system, I’m using Bryant i90 plus furnaces. Geothermal
doesn’t work so well in Utah where I live.

As for Enerzone, are you thinking of using their flex dampers? I used them.
The dampers are great. At least here, they helped get past having to have an
access panel for each damper to comply with electrical codes. However, their
pneumatic controls suck. Their air compressors/vacuums are well, I’d say
mickey mouse, but then that would be derogative to Mickey. I had to
completely rebuild their control system. I now have Enerzone control boxes
with valves, tubing and compressors from companies that make better
products. I like the dampers though.

Good luck on your system.

Hey, that's cool, Rob. Energy savings is something I really want to
concentrate on in our new house. Can you tell us about the HVAC system
you're using? I'm going to put a geothermal one in our new place, and was
thinking of controlling it with Enerzone devices.

Thanks for sharing!

Although the only person on this list is Mark, somewhat, and I simply don’t
have the smarts that any of you have, I have a favorite event. But, again it
’s nothing like anything you have developed. No fancy phones, station
programming, verbal notices, etc.

My favorite event is simple. It manages the HVAC in my house. Unfortunately,
I have one of these events for every zoned room in the house. If any of you
know of a way to do this more elegantly, given what I have, let me know. I
have a motion detector, analog temperature sensor and motorized damper for
each room. My furnaces/AC units are microprocessor controlled. They sense
the amount of air permitted through the system and adjust fan speed and
heat/AC accordingly.

This event has worked really well for me. It has cut my energy bills by an
average of 43% annually. The event determines if someone is there and then
adjusts the appropriate temperature for the room according to season and
time of day.

Anyway, here it is:
