FAQ

Yes. The SAS961 is equipped with dual outputs (relay and dry contact) to synchronize terminal water valves with the central boiler, ensuring maximum energy efficiency and system longevity.

Hydronic systems have high thermal inertia. 0.1°C precision allows the thermostat to detect tiny changes and adjust early, preventing the "too hot or too cold" fluctuations common in 1.0°C precision models.

Absolutely. Through the Tuya WiFi integration, you can easily control your heating using Amazon Alexa or Google Assistant.

No. The device features permanent memory storage. All your settings and 7-day schedules are saved securely and will auto-restore once power is returned.
