What do i need to buy? SO confused like others. A total noob
I have combi boiler with Honeywell controller in hallway which i think talks to a square box next to boiler. It also says Honeywell on it. There is no way to confirm if these two are related. It could be my lack of experience. Any suggestions? on what do i need to buy? Just a smart thermostat or a Wireless Smart Thermostat Starter Kit V3+ with Hot Water Control(thermostat and a rectangular box)?
I have attached some pictures.
Many thanks for your advice
