## Long description

NOWODVORSKI L-4X is a thermostatic valve controller designed for wired and wireless operation with integrated WiFi. The device controls up to four valve sections and provides RS485 communication for integration with building automation systems or external controllers. It is intended for zoned heating installations where both remote access and local actuation of thermostatic valves are required.

The unit supports direct valve actuation and monitoring, allowing coordinated temperature regulation across several rooms or circuit sections.
Suitable for
 Zoned residential heating systems with multiple radiators or manifolds
 Small commercial buildings requiring local valve control and remote monitoring
 Integration with building automation via RS485 for centralized control
 Retrofit projects where a mix of wired and wireless connections is needed

How to use
Mount the controller in a suitable location near the valves or manifold, following local electrical and installation regulations. Connect the valve actuators to the designated outputs and establish the RS485 wired link if integration with a central controller is required. Configure WiFi access and network settings using the device setup procedure to enable remote control and monitoring. After installation, assign each channel to the corresponding zone and verify valve response through local commands and remote interface.
Usage recommendations
Use the RS485 connection for stable, long-distance communication in installations with a central automation system, and enable WiFi when remote access via mobile or cloud services is required. Regularly check electrical connections and firmware updates to maintain reliable operation.
