Vaanster is an energy supplier and therefore the thermostat does not belong to Vaanster. The thermostat belongs to the homeowner. In the case of an owner-occupied home, it is you yourself and if in a rented home it is the landlord.
If you want to replace the thermostat, we do recommend that you always do so in consultation with an installation company. As an energy supplier, Vaanster cannot advise you on this. The thermostat affects the operation of your floor heating.
Tip: Are you looking for more information about the thermostat? Then the thermostat's manual can help. Many manuals are publicly available on the Internet.
