I just had a taco Outdoor reset pc-702 and Taco 6 zone relay installed for $1300. They also reduced the size of my gas orifices from .45 to .48 as per Burnham engineer recommendations. I have an oversized Burnham Revoultion rv5 in a ranch with a heat loss of about 40,000 btu.

I'm only using the Taco outdoor reset for 20 days and I know that is not a proper amount of time to be judgemental but preliminary gas usage is the same or possible more?

I have the design outdoor temp set to 9 degrees. When set at zero it took the largest zone 4 hrs to heat from 67 to 71 degrees (it took about 40 min. w/o the taco). I was told that my Honeywell Visionpro 8000 has to acclimate itself to the Taco and it can take a week.

I have 3 zones with an indirect heater as 4th zone priority, using taco 007 circs with slant fin high output multipak 80 baseboard. Should I just give the system time (1 month) to work itself in or does anyone suspect a problem even though it may be too early to determine. Thanks...

ps. taco settings...boil start= 70, outdoor start=70, boil design=190, boil min supply=80 (was told to go that low cause revolution can handle 55 ret. temps), Diff=Ad, wwsd=70
