Hi @FireFury,
SAT is designed to act as the central controller (or virtual thermostat) for your whole heating system, even if you don’t have a physical central thermostat installed.
How Setup Works
During the initial configuration, SAT asks you to define a main thermostat. This isn’t a physical device, it’s a virtual zone representing your primary room, often the living room (especially if it has multiple radiators). This room typically plays a leading role in regulating overall heating demand.
In the Configure Sensors section, set the Inside Sensor Entity to the temperature sensor in your living room, this is the reference for managing that room’s heating.
Multi-Room Setup (Areas)
In the Areas section:
- Leave the
Thermostatfield empty. - In the
Radiatorsfield, add the climate entities (TRVs) from your living room—the main zone. - In the
Roomsfield, add the climate entities (TRVs) for the other rooms in your home.
How It Works
- When you adjust the SAT setpoint, the living room TRVs will follow that change.
- If only the other rooms (zones) request heat (e.g., bedrooms at night), SAT will provide heating only for those zones, adjusting the boiler’s flow temperature accordingly.
This setup allows SAT to balance energy efficiency and comfort in a multi-zone system without needing a dedicated central thermostat device.
If you have any other questions, feel free to ask.
