Thermostat controller for mutiple radiator valves

Buy offer Details

Dear Sir/Madam,
This is Sunito from Stichting Humaniversity, NL.
We have about 50 rooms with 2-10 hot water heating radiators each. We are looking for a way to control these radiators with one Thermostat per room.
The radiators have Danfoss Valves and turning knobs (see attached pictures)
(RAVL Combi 10/15 013G4017)
We want 1 sample set to try it out and then install thermostats in all the rooms.
Please advise us how to accomplish this task.
Thank you,
Sunito
