The NT20e is still on the wall in the livingroom, but inactive since a year or so; it has been replaced by a Honeywell EvoHome Evotouch (I still have to update my website
). The livingroom is heated with floor heating.
But we kept 2 radiators there to be able to give the temperature in the living a 'boost' if needed, and those valves on the radiators in the livingroom are there to be able to control the radiators without the need to do that manually.
Once everything is in place (I'm not done yet) regarding controlling the temperature in all the rooms and the MAX! system has proven itself, these radiator thermostats will only be used as ON/OFF (for the boost).
