Finnleo SL2-C Control - 24-hour Wi-Fi

Finnleo SL2-C Control – 24-Hour Wi-Fi (For Laava and Magma Heaters)

The Finnleo SL2-C Control with 24-hour Wi-Fi delay is the commercial-grade command center built specifically for Laava and Magma sauna heaters. Designed for facilities and high-use environments where a sauna needs to run continuously or be ready around the clock under attendant supervision, this control pairs a rugged touch interface with full Wi-Fi connectivity so operators can monitor and adjust the sauna from a smartphone, tablet, or the panel itself. Whether you're running a spa, gym, or multi-user sauna suite, the SL2-C 24-hour Wi-Fi keeps your heater precisely managed and always guest-ready.

Wi-Fi-Enabled Remote Control

Built-in Wi-Fi extends control of the sauna beyond the four walls of the sauna room. Using the SaunaLogic2 mobile app (available for iPhone and Android, including tablets), operators can start, stop, and adjust the heater from the front desk, office, or anywhere with an internet connection. The app also integrates with Google Home, Amazon Alexa, and Siri for voice-activated operation, and supports Wi-Fi setup over a 2.4GHz network. Administrators can create a "Family" within the app and add multiple authorized users, making it easy to manage access across staff or household members.

24-Hour Delay Timer

Unlike the 60-minute timer variant, the SL2-C 24-hour Wi-Fi control is built for extended and commercial operation. It allows the heater to run or be scheduled up to 24 hours in advance, which is ideal for facilities with attendant supervision where the sauna must stay heated and ready throughout an operating day. This makes it especially well-suited to health clubs, spas, and commercial wellness facilities where continuous availability matters more than a short single-session countdown. As with all SL2-C controls, maximum operating temperature is capped at 194°F for safety.

Heater and Electrical System Compatibility

The SL2-C control is engineered specifically for Finnleo's Laava and Magma sauna heaters, both built for larger, high-demand, and commercial sauna installations. Laava heaters are available in multiple kW outputs suited to mid-to-large sauna rooms, while Magma heaters are designed for large commercial sauna rooms requiring two or more floor heaters, with outputs ranging from 21.0 kW up to 28.8 kW. Because of these higher electrical loads, correct contactor box pairing is essential: single Laava heaters typically pair with a CB17 contactor box, while higher-output and 208V three-phase Magma installations require a CB17-3 paired with a CB18-3 contactor box. Always confirm heater model, kW rating, and electrical service (voltage and phase) before ordering to ensure the correct control and contactor box combination.

Construction & Design

The SL2-C control features a sleek tempered glass touch panel designed to withstand the heat and humidity of sauna environments while maintaining a clean, modern appearance. The capacitive touch surface responds reliably even in warm, humid conditions, and the display clearly presents time, temperature, lighting status, and connectivity state at a glance. Built to integrate seamlessly with Finnleo's Laava and Magma heater lines, the SL2-C maintains the same design language as the rest of the SaunaLogic2 control family while offering the extended scheduling capability commercial installations demand.
