Some homes have more than one heat source, e.g. one central boiler, and a secondary boiler for a separate part of the house.

You can control these heating systems with one of the following setups:

1. A Smart Thermostat controls one boiler

The Smart Thermostat controls the central boiler. The part of the house supplied from another heat source will act independently without using tado°. For instance, if an additional room thermostat controls your second boiler, we recommend that you do not replace this additional room thermostat with tado°.

You’ll need the following tado° devices:

  • 1x Starter Kit - Wired Smart Thermostat V3+ (includes Smart Thermostat and Internet Bridge)

2. A Smart Thermostat controls one boiler and Smart Radiator Thermostats control the radiators supplied from another heat source

The Smart Thermostat controls the central boiler. Smart Radiator Thermostats independently control the radiators supplied with heat from the second boiler. This way, tado° regulates the entire house.

You’ll need the following tado° devices:

  • 1x Starter Kit - Wired Smart Thermostat V3+ (includes Smart Thermostat and Internet Bridge)

  • Add-on - Smart Radiator Thermostats for each radiator supplied from the second boiler

3. A Smart Thermostat controls the boiler, and additional Smart Thermostats control the water-based underfloor heating supplied from another heat source

The Smart Thermostat controls the central boiler. Additional wired Smart Thermostats independently control the water-based underfloor heating rooms. This way, tado° regulates the entire house.

You’ll need the following tado° devices:

  • 1x Starter Kit - Wired Smart Thermostat V3+ (includes Smart Thermostat and Internet Bridge)

  • Add-on - Smart Thermostats for each room with underfloor heating supplied from the second boiler
