KEEP YOUR HEATING AND COOLING SYSTEM SAFE
Welcome to the future of building services!

We are pleased to introduce Nolsen’s remote-access monitoring system, Sentra, which takes heat pump management to a new level: it provides maximum peace of mind for end users and valuable time savings for installers.

The system supports heating and cooling control, pump control and zone control, among other functions – not just monitoring – and also enables remote diagnostics and configuration, all without an on-site visit.
Nolsen’s remote monitoring devices are universally compatible with virtually any heat pump*, and are especially recommended for Gree products, where functionality and compatibility are outstanding.

Unlike other systems, Nolsen system devices do not require additional modules. The device can be used as a fully functional standalone solution with virtually any heat pump that has a Modbus interface.

* A Modbus interface is required.

KEY FEATURES OF NOLSEN REMOTE-ACCESS SMART DEVICES

The device can be continuously updated, allowing new features to become available in the future without additional hardware.

Remote configuration

Through Nolsen’s web interface, heat pump settings can be changed from anywhere: heating, cooling, domestic hot water and operating mode – all just a click away.
Users can have peace of mind about their homes, while installers save time and avoid unnecessary site visits. Every change is logged automatically, keeping the system transparent and reliable at all times.

Real-time data display

The system displays real-time data in charts and on the dashboard: temperature, pressure and flow – every detail matters.
With data logging updated as often as every 5 seconds, any period can be reviewed, faults can be identified quickly and optimization becomes straightforward.
Transparent operation, accurate diagnostics, fewer site visits

Comprehensive heating and cooling control

Control complete systems in both smaller and larger buildings – heating, cooling, zone control, pump control and full plant-room management.

Notifications and alerts

Nolsen’s multi-level notifications help detect irregularities in time – before they become a problem.
If a fault can be resolved remotely, the system intervenes automatically. In the event of a more serious malfunction, it provides a clear picture of the required repair so technicians can arrive prepared. This means less stress for users and faster troubleshooting and more efficient work for installers.
