If all of my radiators have Wiser Radiator Thermostats, do I need the Room Thermostat?

The Wiser Room Thermostat isn’t required for the system to work but it is recommended to have 1 or 2, as it provides a visual temperature reading and improves accuracy. If, for example, you have an open plan space with multiple Wiser Radiator Thermostats you should ideally use a Wiser Room Thermostat as a central control to maintain accuracy. The Wiser Room Thermostat also allows you to boost or override the room from one point in the home for the zone it is assigned to.
