How does tado° control a multi-zone radiator heating system?

In most heating setups with multiple zones, room thermostats regulate zone valves that provide heat for all rooms in each zone based on the temperature measured and/or a set schedule.

In these cases, Smart Thermostats replace the room thermostats and allow to control the zones individually with tado°.

You can enhance this setup by replacing an installed programmer with an Extension Kit.

Smart Thermostats control radiator zones independently

Smart Thermostats control the zone valves independently based on the room temperature measured in the respective zone.

The temperature in individual rooms is controlled by changing the settings on the radiator thermostats.

Smart Thermostats control zone valves and the Extension Kit controls the boiler

The Smart Thermostats control the zone valves based on the room temperature measured in the respective zone.

The Extension Kit will turn on the boiler when any of the Smart Thermostats request heat and opens the respective zone valve. The temperature in individual rooms is controlled by changing the settings on the radiator thermostats.

One Smart Thermostat controls the boiler and the zone valve, another Smart Thermostat only controls the zone valve and one Extension Kit turns on the boiler

The first Smart Thermostat has an integrated timer and controls both the zone valve and the boiler. The second Smart Thermostat only controls the zone valve.

The Extension Kit will turn on the boiler when the second Smart Thermostat requests heat and opens the respective zone valve.
