Thermostatic head FLOW PRO

Overview
FLOW PRO is a smart LoRaWAN-connected thermostatic head for multi-unit buildings combining local regulation, long battery autonomy, NFC setup and centralized monitoring via LoRaWAN.

Key benefits

• Connected: quick NFC setup via smartphone; remote control and monitoring over LoRaWAN.
• Reinforced mounting: RUG base with metal inserts for demanding communal environments (schools, hospitals, housing, hotels, offices).
• Long battery life: operates with 4 replaceable professional AA lithium batteries; declared up to 12 years depending on settings and usage.
• Local regulation and autonomy: onboard schedules and direct radiator regulation continue to operate without wireless connection.
• Precise control: thermostatic adjustment in 0.5 °C steps and stepper motor with micrometric positioning.
• Fleet management: remote programming, centralized control and monitoring via NAVIXIS; remote firmware updates (FUOTA V2).

Functional features

• Support for NODE remote sensor: measures room temperature away from the radiator for improved regulation; NODE accuracy ±0.5 °C; auto measurement every 10 minutes.
• L2D1 local radio link: direct communication between NODE and FLOW for local operation without LoRaWAN dependency.
• Optimized LoRaWAN usage: transmissions limited to essential information; historical mode and redundancy to maximize reception.
• NFC local configuration: simple smartphone-based setup independent of immediate LoRaWAN availability.
• ADAPT compatibility: adapter kit for common thermostatic valves (Danfoss RA/RAV/RAVL, Cale, Giacomini, M28, etc.) for retrofit installations.
• Anti-seize function, open-window detection (30-minute heating pause), control lock, anti-tear/anti-theft mounting with tamper alerts.
• Optional CASE protective shell for exposed communal environments.
• Battery monitoring and AES-128 end-to-end encryption for data security.

Integration & maintenance
Integrates with building management systems (BMS) and the NAVIXIS IoT platform to control setpoints, monitor devices and batteries, manage schedules and configure alerts for remote maintenance prioritization. Remote software and firmware updates reduce on-site interventions.
