    Ah, now that looks slick!

    Never used that version, but I've rarely if ever had problems with the other line of stat that is basically the same.

    I thought more of the membership would have seen this.

    Looks like a VP with the old board that the PC8900 had.

    Very, very close, actually has more features then the old PC8900/W8900 combos. How about this...soon to be available in a 'wireless model', T8665's getting replaced next. Can't wait, entire Chrono line being replaced. The YTH model is just beginning to ship at the end of this month.

    in the Comments section of this thermo (link above), it states partially "...Dehumidification using Whole House Dehumidifier or Air Conditioning with High or Low speed fan..."

    will it also energize Y/Y1 ?

    Here's a reply from Honeywell (they didn't answer if this thermo will energize Y/Y1 but perhaps we can assume that's what it'll do on a 2-stage system?)

    **
    For dehumidification, the thermostat can work in two different ways
    depending on its configuration. If it is set-up to control a whole
    house dehumidifier, like our DH90, it will bring on the dehumidifier
    with a call for dehumidification. If it is set up to dehumidify using
    your air conditioning system, it will look at two things, the
    dehumidification setpoint and the room temperature setpoint. If based
    on the dehumification setpoint it determines that it is necessary to
    bring on the cooling, it can allow the system to run and possibly cool
    past the room temperature setpoint by 1, 2, or 3 degrees depending on
    configuration. It will not over cool more than this in order to
    maintain your comfort. During a call for dehumidification, the
    thermostat will call for low speed fan, rather than the typical
    high-speed fan of a standard call for cooling.
