S-A2446 GSM LTE-4/5G LCD Switch

Sunster A2446 GSM LTE-4G/5G Smart Switch Controller

The Sunster A2446 Switch is our latest innovation, designed to give you complete remote control of your diesel air heater. Unlike traditional controllers limited by distance, the A2446 uses LTE 4G/5G GSM technology to ensure stable, unrestricted operation worldwide.

Key Features:

True Remote Control: Insert a nano-SIM card (not included) and manage your heater from anywhere—no distance limits.

Smart Thermostat Mode: Automatic start & stop keeps your space at the perfect temperature while saving fuel.

Multi-Function Display: Digital LCD panel with clear readings for temperature, status, and fault codes.

Turbo Heat & Ventilation: Choose between rapid heating, standard heating, or simple air circulation.

Timer Scheduling: Pre-set heating times for comfort and convenience.

Language Options: German / English / Russian / voice-off selection.

Safety Alerts: Displays up to 9 fault codes for quick troubleshooting.

Universal Compatibility: Works with Sunster 12V/24V heaters and AC 110–240V power supply setups.

Why It Stands Out:
The A2446 is not just a switch—it’s a smart hub for your diesel heater. Whether you’re in your RV, garage, cabin, or boat, you can start heating before you arrive, ensuring instant comfort.

🔥 Upgrade to the Sunster A2466 GSM LTE Controller and enjoy limitless control, safety, and efficiency—wherever the road takes you.
