Does anyone know of a local manufacturer that makes and sells a programmable TRV? I know Danfoss makes one, but it isn't in the US market yet. I'm also looking for one with the remote wallmount operator- but programmable. Thanks in advance. Caleffi guys? This seems to be right up your alley- I can't believe these wouldn't sell like hotcakes.

    I have seen them on ebay but I have not heard any reliable feedback. They even have Bluetooth enabled models.

    Do the programmable Danfoss heads work on the single pipe steam valve bodies?

    The Caleffi programmable is also a Euro model, metric units. I tried one on the radiator next to the bed. The gear train noise was a bit loud. Program it for your wake up time

    Hot Rod - so Caleffi makes one but not with a wall-mount operator?

    Here's a manual for Danfoss programmable head. It looks like it comes with adapters for different valve bodies: http://heating.danfoss.com/pcmpdf/living-eco_viidb202.pdf

    Not positive what the of body is steam one.

    Jeff, What did you end up using?
    DIY'er ... ripped out a perfectly good forced-air furnace and replaced it with hot water & radiators.
