HARVIA XENIO WIFI

Harvia Xenio WiFi control panel is designed to control Harvia sauna devices: control center, electric heater or combi-heater. With the control panel it is also possible to control accessories like the lighting and ventilation of the sauna room. The ability to control accessories depends on the connection options of the device being controlled. Xenio WiFi control panel can only be connected to compatible Harvia products. See the manual of controlled device for more device-specific information.
The Xenio WiFi -control panel can be controlled by using MyHarvia mobile application. With the mobile application you can, for example, see the status of the heater, temperature of the sauna room and remaining heating time anywhere, anytime.

1. INSTRUCTIONS FOR INSTALLATION
The control panel is splashproof and has a small operating voltage. The panel can be installed in the washing or dressing room, or in the living quarters. If the panel is installed in the sauna room, it must be at the minimum safety distance from the heater and at a maximum height of one metre (1m) from the floor. Conductor tubing (ø 30 mm) inside the wall structure allows you to thread the data cable hidden within the wall – otherwise the installation will have to be on the wall surface. If the control panel is exposed to water splashes, flush mounting is recommended. The existing Xenio control panel can be replaced with Xenio WiFi panel without an electrician.
» See Figure 2 Installing the control panel

Install the control panel in a location with a good WiFi connection. You can ensure an adequate WiFi connection with your phone :

Disable mobile data on your phone.
Turn on your phone’s WiFi.
The WiFi connection at the installation location is adequate if the WiFi connection of your phone is good and other applications that require data transfer work properly.

If the connection is not adequate :

Try another location.
If possible, change the location of your WiFi base station so that the connection to the Xenio WiFi control panel is better.

Building structure, building materials, flush mounting and other similar issues may reduce the quality of the WiFi connection.
Tip! A WiFi network extender can be used to enhance the network reach.

INSTALLING THE CONTROL PANEL

A) Surface mounting
B) Flush mounting HARVIA CX004WIFI Xenio WiFi - INSTALLING THE CONTROL
PANEL

Thread the data cable through the hole in the back cover.
Fasten the back cover to a wall with screws.
Push the data cable to the connector.
Press the front cover into the back cover.

3. INSTRUCTIONS FOR USE
Using the Heater and the Steamer
When the device is connected to the power supply and the main switch (further information » System components) is switched on, the control unit is in standby mode and ready for use. I/O buttons’ background lights glow on the control panel. (Device = power unit / Harvia XE-heater)
Heater and/or Steamer On:
Heater and steamer are switched on and off independently.

Start the heater by pressing the heater I/O button on the control panel.
Start the steamer by pressing the steamer I/O button on the control panel.

When the heater and/or steamer starts, the display will show previously set values for five seconds. The shown values (temperature/humidity/on-time) differ depending on which devices are started.
When the desired temperature and/or humidity has been reached in the sauna room, the heating elements are automatically turned off. To maintain the desired temperature and/or humidity, the control unit will automatically turn the heating elements on and off in periods. If the heater efficiency is suitable and the sauna has been built correctly, the sauna takes no more than an hour to warm up.

Heater and/or Steamer Off:
The heater and/or steamer turn off and the control unit switches to standby mode when:

the I/O button is pressed
the on time has elapsed or
an error occurs.

If the water container runs empty, the steamer will be turned off, the water level warning light will blink, and the display will show the text “OFF”. If the water level sensor develops a failure, the steamer’s overheat protector will engage, the water level warning light will blink, and the display will show the text “OFF” (further information » Error Messages).
NOTE! It is essential to check that the control unit has cut off power from the heater after the on time has elapsed, the dehumidification has ended or the heater has been switched off manually.

Changing the Settings:
The settings menu structure and changing the settings is shown in figures 3a and 3b. The programmed temperature and humidity values and all values of additional settings are stored in memory and will also apply when the devices are switched on next time.
Note! The humidity value determines the maximum temperature in the sauna. The sum of temperature and humidity values can be 140 at maximum (temperature 60 °C + humidity 80 rH). This is due to safety reasons. If the steamer is activated and you try to set the temperature too high, the humidity value will blink in the display.

Using Accessories
Lighting and ventilation can be started and shut down separately from other functions.
Lighting
The lighting of the sauna room can be wired so that it can be controlled from the control panel. (Max 100 W.)

Switch the lights on / off by pressing the control panel button.
Ventilation
If there is a fan installed in the sauna room, it can be connected to the control unit and be controlled from the control panel.
Start / stop the fan by pressing the control panel button.
Safety switch
Safety switch (e.g. Harvia SFE) refers to a device that is integrated or installed above the heater. It prevents the heater from heating up if, for example, a towel (or some other object that might cause a fire hazard) is placed on it. » See Safety switch Instructions for Installation and Use.

Note! Safety switch may only be connected by an electrician.

Remote switch
To remotely control the heater’s power input, the control unit can be equipped with an on/off remote switch (e.g. building automation) (further information » System components) (further information » 4.
