    Quick questions for everybody installing the Buderus GB142.
    1) Are you using the RC10 as an indoor reset or making it an on/off boiler with an outdoor reset?
    2) Is anybody experiencing any short cycle codes?
    3) Does anybody know how to set the speed on the boiler circulator?

    I've seen the RC 10 used for the boilers indoor reset. I haven't seen anyone set it up on/off. I've heard of people using the boiler with out the RC 10, letting the unit modulate based on the sensor in the return of the boiler. The only short cycle insident I've heard of was on a baseboard job that was under radiated and using the RC 10. The delta t was like ten degrees, the btu's where coming back to the unit when the RC 10 was telling the boiler to ramp up. It caused the boiler to be a little confused. That was the only thing I've heard..
