The io radiator thermostat combines two principles. On the one hand, its clean, unobtrusive design allows it to integrate harmoniously into any interior; on the other, it enables the user to control energy consumption at any time. Every radiator can be regulated individually remotely by app or voice control, or manually on site through the simple touch of a switch on the front. This makes it possible to reduce heating costs and heat selected rooms to the desired temperature at a given time. The smart thermostat also detects open windows and automatically reduces the heat output.
