I would like to change my thermostat to a wifi unit.  It uses 2 wires and controls a Viessman Vitogas 100.  Pls advise what thermostat I can use.  There is no C wire.

    No C wire? You will have to use an outboard power unit for any wi-fi thermostat -- but several makes do have such things available. I prefer Ecobee, but Nests also work...
