A pre-purchase question !!!
Considering buying a Tado smart thermostat but I have question. I currently have a supported Vailliant combi boiler but have a wired thermostat in the hallway and a separate controller in the kitchen. I would like to replace both of these with a wireless smart thermostat but..... this is a rented property and I need to leave the old stat and controller in place along with their wiring. Am I right in assuming that this can be done by removing/bridging the existing wired controls and installing the wireless controller? If we ever move I will have to put the system back to its original state prior to this upgrade
Any advice or recommendations would be greatfully received
