    Thank you. That was very helpful.

    BTW, it's wunderground.com, not wonderground.com!
  2. How can I measure energy savings of new furnace?

    This seems like such an easy question, but I believe it is hard to come up with an accurate way to measure.

    The easiest is to look at a time frame (winter) before putting in the furnace and then...

    I have an IAQ. Wouldn't if be nice if I could set my thermostat for dew point instead of temp?

    As clarification, I want the unit to use the upstairs remote sensor at night and the downstairs sensor during the day. If it was in the program, I could set that once and be done with it, but since...

    I'm a HO with a dual fuel set-up (2 stage hp and 2 stage furnace) and I choose the 9421 over the 8320 at install because of the extra things it can do for that set-up. There are a few things that...

  8. I'm trying to find the balance between A/C and whole house fan usage

    A little background. We have lived in Colorado for 17 years and we have never had an A/C. Up until this year, we used an evaporative cooler during the day and our whole house fan at night. And it...

    It seems like the remote sensor and using average is the least painful solution. The only issue is that the differential between up and down varies and finding the right setpoint will be the...

    And that is another problem with my system. My setup has 4 heat / 2 cool and I'm only aware of one zone board that can be used and it doesn't work with dual fuel. And I read on another thread that...

    beenthere:

    I actually leave the fan on all the time and it does a decent job of averaging out the room temps. It does much better at night than during the daytime. And doing what you suggest is...
  12. Can I have 2 thermostats connected to my system?

    I have an dual fuel system (American Standard Heritage 16 HP, Freedom 80 furnace) and an Honeywell IAQ thermostat.

    What I would like to do is have a thermostat or sensor on the 2nd floor so that I...

    Zoning with an AS Heritage 16 DF system

    Last fall, I had the following dual fuel system installed:

    American Standard Heritage 16 Heat Pump (2 step compressor)
    AS Freedom 80 2 stage VS furnace
    Honeywell IAQ thermostat

    I was quite...

    Ryan:

    Thanks! That is exactly this problem. Operator error! Although it seems strange that turning off the system doesn't override the fan schedule, IMHO.
  16. IAQ problem, wiring problem or IAQ set-up issue?

    I had an AS Heritage 16 and Freedom 80 furnace installed last fall. I control the system with an IAQ. I really enjoyed the comfort this past winter. The VS was wonderful!

    Up until now, I have had...

    Thanks guys. It looks like I'll just leave things the way they are now.
  18. What's the value of Comfort-R in a low humidity climate?

    Last fall I had an AS dual fuel system installed. The installer didn't set it up for Comfort-R. After reading all the threads, it appears that the value of Comfort-R is to control humidity. Since I...

    I really don't want to lose adaptive recovery. The backup is gas and I only set it back 4 degrees (67 --> 63). However to get to 67 by 6am, it starts recovering at around 4am when temps are around...

    Can I do this with an IAQ Thermostat?

    Since it takes several hours for my heatpump to recovery every morning, I was wondering if I could set the wake schedule on my IAQ to use the gas heat instead of the HP. Is that possible?

    Second:

    Why is that important? I have seen that in a few other threads. I know mine is not run on a separate set of wires.

    That is the conclusion I came to and decided not to do that.



    That is my plan.



    As advanced as the IAQ is, that is one feature that is lacking. I was quite disappointed when I...
