Harvia Fenix FX110 WiFi: Buying Guide

From Order Confirmation to Your First Mobile-Controlled Session

The Fenix FX110 WiFi isn't just a switch; it is the central nervous system of your sauna. This unit allows you to preheat your sauna from your phone, manage lighting, and even control ventilation. Because it is IPX5 rated, it’s built to handle the humidity of a spa environment.

1. Is this the right "Brain" for your Heater?

The Fenix FX110 is designed to control "E" model heaters (like the Top Steel E or Cilindro E).

• Power Capacity: It can handle heaters up to 11 kW.
• The WiFi Factor: You must have a 2.4 GHz WiFi signal reaching the location where this unit is installed to use the MyHarvia app features.
• The IPX5 Advantage: Unlike older control panels, this unit is highly water-resistant. While we still recommend mounting it outside the sauna room, it is much more durable against steam and splashes.

2. The Delivery (The "Tech" Arrival)

• The Package: This is a smaller, lighter parcel than a heater. Inside, you will find the Power Unit (the relay box), the digital Touch Panel, a temperature sensor, and a data cable.
• The 24-Hour Inspection: Digital screens are sensitive. Unbox the touch panel immediately and check the glass for any cracks or chips from shipping. Let us know within 24 hours if it isn’t pristine.

3. The Setup (What to prepare)

1. The App: Download the MyHarvia app on your smartphone now. You can set up your profile while you wait for delivery.
2. Mounting Location: You need two spots. One for the "Power Unit" (usually hidden) and one for the "Touch Panel" (usually at eye level near the sauna door).
3. Data Path: Your electrician will need to run a low-voltage data cable between the Power Unit and the Touch Panel. Plan this route now to avoid messy surface-mounted wires later.

4. The Professional Installation

This is a sophisticated piece of electronics.

NOTICE: You must consult a Registered Electrician. This unit handles the main power for the heater and the logic for the safety sensors. You must always defer to your electrician’s professional judgment.

• WiFi Strength: If your sauna is in a garden building, check your WiFi signal there. You might need a WiFi extender to make the "Smart" features work.
• The Sensor: The included sensor is the heater's only way of knowing the temperature. It must be mounted on the ceiling exactly as the manual dictates.

5. First Use (Going Digital)

1. The Pairing: Once the electrician has powered it up, you will pair the Fenix to your home network via the app.
2. The Safety Check: Harvia’s WiFi system includes a "safety start." If you plan to start the sauna remotely, you must ensure the sauna door is closed and no towels are left on the heater.
3. First Heat: Use the touch panel to set your desired temperature. You’ll hear a "click"—that’s the Fenix engaging the heater elements.

Owner’s Brief for the Harvia Fenix FX110 WiFi Control Unit

CRITICAL NOTICE: The information below is for your project planning and budget estimation. You must consult a Registered Electrician to carry out this installation. The Fenix FX110 manages high-voltage loads and safety-critical sensors; you must always defer to your electrician’s professional judgment regarding the safety and capacity of your property's electrical system.

1. System Load & Capacity

The Fenix FX110 is a power controller. It takes the main feed from your consumer unit and distributes it to the heater and accessories.

Note: Accessories include items like sauna lights and ventilation fans, which are also wired directly into the Fenix Power Unit.

2. Infrastructure Requirements

As the owner, you need to ensure your electrician has considered the following:

• The Power Unit Location: This box needs a permanent home. It is IPX5 rated, but it still requires air circulation. Discuss with your electrician whether it should be mounted on the sauna roof or in a nearby service cupboard.
• Data Cable Paths: There is a low-voltage data cable that runs from the Power Unit to the Touch Panel. This needs to be chased into the wall or hidden behind cladding before the sauna is finished.
• WiFi Signal: For the "Smart" features to work, the Power Unit must be within range of your home WiFi. Your electrician may need to install an external antenna or a WiFi extender if the signal is blocked by the sauna's insulation/foil.

3. Mandatory Installation Standards

Ensure your electrician adheres to these standards to maintain safety and warranty:

• Heat-Rated Wiring: While the Fenix sits outside the hot zone, any cables passing through or into the sauna (to the heater or sensors) must be SiHF-JB Silicone Cable (rated to 180°C).
• Dedicated Circuit: The Fenix system must be on its own dedicated circuit, protected by an appropriately rated RCBO (Residual Current Breaker with Overcurrent protection).

4. Final Safety Certification

Once the Fenix system is live and the app is paired, your electrician is legally required to provide you with an Electrical Installation Certificate (EIC).

• Store this document securely. Harvia requires the EIC to validate your 2-year warranty. Additionally, your home insurance may require this to prove that the smart control system was installed by a qualified professional.

Action Plan for the Property Owner

1. WiFi Audit: Stand where the sauna will be and check if your phone can browse the web smoothly on your 2.4GHz network.
2. Electrician Consultation: Show them the Fenix technical specs to confirm your home's total load capacity (especially if you are installing an 11kW heater).
3. App Setup: Download MyHarvia so you are ready to pair the device as soon as your electrician finishes the wiring.

Harvia Fenix FX110 WiFi: Delivery & Installation Protocol

Setting up the central nervous system of your sauna.

The Fenix FX110 WiFi system consists of three main parts: the Power Unit (the heavy lifting), the Control Panel (the interface), and the Sensors (the safety). Because this is an IPX5-rated smart system, the placement of these components is key to a successful setup.

1. Receiving the System

• The Parcel: Unlike the heaters, this arrives in a compact box. Ensure all four core components are present:

1. The Power Unit (Black relay box).
2. The Fenix Touch Control Panel.
3. The Temperature Sensor with its cable.
4. The Data Cable (connecting the panel to the power unit).

• The Screen Check: Inspect the glass touch interface under a bright light. If there are any hairline cracks or deep scratches, stop the installation and contact us with photos within 24 hours.

2. Component Placement

• The Power Unit: This is the relay hub. While it is IPX5 rated (water-resistant), it is best practice to install it in a dry, ventilated area—such as a plant room, a cupboard, or on top of the sauna cabin. It should be accessible for future maintenance.
• The Control Panel: This is typically mounted outside the sauna at eye level near the door. The Fenix panel is sleek and thin; it can be surface-mounted or recessed into the wall for a flush finish.
• The Sensor: This must be mounted on the ceiling, centered directly above your "E" model heater. This allows the Fenix to monitor the heat accurately and engage the safety cut-out if needed.

3. WiFi Connectivity Prep

The "Smart" features of the FX110 rely on a stable 2.4 GHz WiFi connection.

• Signal Strength: If your sauna is in a garden room or a basement, check the signal with your phone at the exact spot where the Power Unit will be mounted.
• If the signal is weak: You will need to install a WiFi extender or a hardwired access point before the electrician completes the commission, or the app features will not function.

4. Physical Installation Steps

1. Cable Routing: Before the walls are closed/clad, your electrician needs to run the low-voltage data cable from the Power Unit to the Control Panel location.
2. Sensor Mounting: The sensor cable is run behind the cladding to the ceiling point. Ensure the sensor is not placed near an air intake vent, as this will result in false temperature readings.
3. App Pairing: Once the power is live, open the MyHarvia App. The Fenix will generate its own temporary WiFi hotspot. Connect your phone to it, enter your home WiFi details, and the system will sync to the cloud.

5. The Initial Safety Test

• Manual Override: Test the Touch Panel first. Ensure the heater turns on and off via the screen.
• Remote Start Test: Once paired with the app, test the remote start from another room.
• Door Sensor (Optional but Recommended): If you are using remote start, we strongly recommend installing a Harvia Door Sensor. The Fenix is designed to detect if the door is open, preventing the heater from starting if the room isn't sealed.

Harvia Fenix FX110 WiFi: Warranty Statement

Protecting your smart sauna investment

IMPORTANT SAFETY NOTICE: The Harvia Fenix FX110 is a sophisticated electronic control system. You must consult with and employ a Registered Electrician for the installation. This system controls high-amperage heater elements and safety-critical sensors; self-installation or failure to follow professional guidance will result in the immediate voiding of all warranties and may pose a significant fire and safety risk.

1. Coverage Periods

Your warranty protects against manufacturing and material defects:

• Domestic/Private Use: 24 Months (2 Years).
• Commercial/Professional Use: 24 Months (excluding wearable parts).
• Note: Wearable parts like sensors or fuses may have a shorter coverage period (typically 6 months) under heavy commercial use.

2. The Professional Standard (Installation)

The Fenix FX110 manages the "safety loop" of your sauna. For the warranty to be valid:

• Certified Installation: The unit must be installed by a Registered Electrical Contractor.
• The EIC Mandate: You must retain the Electrical Installation Certificate (EIC) provided by your electrician. This document is required to prove the unit was correctly earthed and fused. Harvia will request this certificate for any warranty claim.
