Wiser is an intelligent control solution for heating systems which can be easily retrofitted. The Wiser Radiator Thermostat features an innovative and user-friendly design that enables precise control of room temperature. It can be easily operated using the innovative “twist top boost” feature. A simple twist to the left or right will adjust the temperature, up or down accordingly. The LED display blends with the contemporary design and gives clear and simple feedback to the user. A chrome ring and a subsequent chamfer divide the device into its functional areas.
