    This control has 7 outputs (120V) 3 are variable speed triac relays, 3 relay outputs are standard, one is a dry contact. The V-bus allows a laptop or datalogger to be installed. It can have up to 4 outdoor reset functions (weather compensating)

    Irradiation sensor available for drainback, possibly evac tube solar users. Or other clever uses :)

    A couple of unique features... a sensor can be used as a thermostat function, and also be used in a delta t function. This could eliminate having to use multiple sensors in one location.
    Each output can be programed to enable according to the time of day. Maybe block out the boiler, during the day, when solar or wood is in use?

    You can "link" requirements as in switches in series. Maybe a t-stat or vent damper end switch to satisfy first.

    It's intended to be a powerful solar controller, but with multiple delta t functions and thermostat functions it should be right at home as a wood boiler, etc control.

    No UL at this point, and they read C not F. 120V. I have a sample coming my way, I expect to see them available within a month. List around $900.00. Trade purchasers could use a typical multiplier.

    Could give the NFCS a run for its money ;-)

    i've seen references to this. Seems like a nice and well though out unit. I'd love to get first-hand impressions.

    Yeah but it costs $900! The arm board has WAY more capability. That box won't be able to host a web server or grab forecasts from the web or control irrigation, etc.

    I am not saying there is anything wrong with that unit, just that the nfcs (or a competitor ;^)) has a lot more capability for cheaper.
