RF (Radio Frequency) Heating Controls operate without an internet connection and use radio frequency signals to transmit information between the thermostat and the boiler or receiver unit. An RF heating control offers manual control for temperature settings and schedules. It is suitable for users who prefer a simple system without relying on technology. A Smart (Wi-Fi) Heating control uses the internet and enables advanced features like remote control, geofencing, etc. via apps. It appeals to users who value convenience, energy savings, and smart home integration. When suggesting controls to customers, consider both the possibility of long-term energy savings and their degree of familiarity with technology.
