Do I need Smart Radiator Thermostats in the room in which I already have a Smart Thermostat installed?

When you control your heating system (boiler) with a tado° Smart Thermostat you can optionally add Smart Radiator Thermostats to your system to control zones individually. When controlling multiple zones individually with tado°, each zone can issue a call for heat to the boiler through the Smart Thermostat.

If you install Smart Radiator Thermostats, it is recommended to also equip the radiators in the room in which the Smart Thermostat is located with Smart Radiator Thermostats which will turn down the heat supply to the room when the call for heat for that zone is satisfied while another zone might still request heat.
