Heat Timer necessary with Danfoss valves?

Hi I'm just wondering what you're opinions are about doing a steam conversion over to individual thermostatic radiator valves. Can a central t-stat still be used or should an outdoor controller be installed? If so, what is the cheap, simple one that is appropriate for residential application?

Thanks a lot.

    With residential steam, TRVs will prevent rooms from overheating but they cannot tell the boiler to produce steam.

    You can certainly use a true Heat Timer, but neither or they cheap nor inexpensive to substitute.

    If you don't use the Heat Timer (with TRVs on your rads), place the central thermostat in the naturally coolest, occupied space. A frequently used non-kitchen entry is good as is an interior hallway.
