SaunaLogic 2-Commercial Wi-Fi Control - Total Control, Anytime, Anywhere

The Finnleo Magma Heater comes with the SaunaLogic2 Control – a sleek, modern touchscreen that puts your sauna settings right at your fingertips. And the best part? It’s Wi-Fi enabled, so you can control your sauna from anywhere using your smartphone or tablet.  

The Finnleo Magma heater comes paired with the advanced Saunalogic2 (SL2-C) control package. This isn’t your average sauna dial!

  • Sleek Digital Interface: The SL2-C features a modern, easy-to-read digital display, showing the current temperature and allowing for intuitive adjustments.

  • Remote Installation Capability: One of its biggest advantages, especially for commercial settings, is the ability to install the main control unit outside the sauna. This means sauna users can enjoy the heat without being able to alter pre-set temperature limits or run times, ensuring consistent operation and energy management.

  • Programmable Run Time & Temperature: You can precisely set your desired sauna temperature and how long you want the sauna to operate.

  • Door Switch Integration for Safety & Efficiency: As mentioned, it works with a door interlock switch. If the sauna door is opened and remains open, the heater will automatically shut off. This is a critical safety feature and also helps conserve energy.

  • Optional External On/Off: The system supports an optional external, low-voltage on/off switch for user convenience.

  • WiFi/App Control: The provided information on the SL2-C specifically for the Magma doesn’t explicitly mention WiFi or app control. While some Saunalogic controls offer this, it’s crucial to confirm if this specific “SL2-C” version bundled with the Magma has app capability. We can verify this for you! If it does, this would allow you to power on and monitor your sauna remotely from your phone – ultimate convenience!

The SL2-C control elevates your sauna experience by making it smarter, safer, and more convenient to operate, especially in high-use or commercial environments.

Commercial Sauna Heater Common Questions

Here are some of the most common questions people ask.

All of our Sauna Heaters are designed to be used with or without water. We recommend allowing patrons to pour water to produce steam, as it’s an essential part of the sauna experience and better for the longevity of the wood in the sauna.

With that being said, we understand if businesses want to achieve a dry Sauna experience. The sauna will still work good without water. You can advise users not to pour water over the rocks but you shouldn’t restrict the heater in any way. Even if you ask, patron tend to ignore warnings and pour water on the rocks.

Whether or not you choose to try restrict it, it’s essential that they are using clean water, and nothing with chemicals (i.e. pool water is bad). 

Absolutely. While the Laava and Magma heaters are the biggest heaters, for business owners with a smaller Sauna, consider one of our other Electric Sauna Heaters.

Mobile Saunas on a trailer provide a unique opportunity for the mobile business owner. If you have a power source, take a look at one of our smaller electric heaters or consider using one of our wood burning sauna stoves.

Getting a commercial sauna heater is quick and easy.  Either give us a call at 612.505.9700 or submit a contact form through our website.  Delivery or pick-up is available.
