LoRaWAN connected thermostatic radiator valve for collective buildings

FLOW PRO is a LoRaWAN connected thermostatic radiator valve designed to improve heating control in collective housing, hotels, schools, hospitals, offices, public buildings and tertiary facilities.

Installed directly on a hot water radiator, FLOW PRO regulates heating room by room according to setpoints and schedules stored in memory. This local regulation helps reduce overheating, improve occupant comfort and optimize energy consumption across the building.

Thanks to its LoRaWAN connectivity, FLOW PRO enables remote supervision, parameter updates, equipment monitoring and centralized heating management. It is designed for building managers who need a robust, scalable and reliable solution for connected heating control.

Local regulation, even without network connection

FLOW PRO stores its heating schedules directly in memory. This means the thermostatic radiator valve continues to regulate heating locally, even if the LoRaWAN network is temporarily unavailable.

The wireless network is used to supervise equipment, adjust parameters, receive alerts and update the product remotely. The heating regulation itself does not rely on permanent cloud commands, which improves operational continuity.

Designed for BMS and professional buildings

FLOW PRO is designed to support Building Management System strategies. It helps operators manage heating schedules, adjust setpoints, monitor equipment status and optimize thermal comfort across a building or multi-site property portfolio.

Its reinforced design makes it suitable for demanding shared environments such as schools, hospitals, collective housing, hotels and public buildings.

Up to 12 years of battery life

FLOW PRO operates with 4 replaceable lithium AA batteries and can reach up to 12 years of battery life depending on product settings and usage conditions.

This long battery life helps reduce maintenance campaigns, limit on-site interventions and simplify the management of large equipment fleets.

More accurate regulation with NODE

The temperature measured directly at the radiator can be affected by heat convection, sunlight, curtains or air drafts. FLOW PRO can be combined with the NODE remote temperature sensor to measure the actual room temperature away from the radiator.

This improves regulation accuracy, stabilizes comfort and helps maintain a temperature closer to the defined setpoint.

Designed for the FLOW ecosystem

FLOW PRO is part of the Nexelec FLOW ecosystem. It can be combined with the NODE remote temperature sensor for more accurate room temperature measurement, ADAPT adapters for installation on existing radiators, CASE+ protective cover for shared environments and NAVIXIS for remote supervision.
