3.1. General
According to the product standard IEC/EN 60335 -2-53 regulating electrical sauna heaters, a
control unit can be used to remotely control the heater once the heater or sauna room door is
equipped with a secure switch (a safety or a door switch).
Remote use with the safety switch: The heater can be turned on remotely if the safety switch circuit is
closed. If the circuit is open, ”SAFE” is displayed and the heater will not start.
Remote use with the door switch: Remote use mode must be activated by pressing the
heater button for three seconds. If the door switch circuit is open, remote control mode
will be activated after 30 seconds (30-second timer allows remote control to be activated
even when the control panel is installed inside the sauna room). Status message ”rc”
and the remaining time for remote control activation is displayed. Heater and steamer
buttons (in case the steamer function is possible) are blinking. After 30 seconds “rc
on” is displayed and the heater can now be turned on with a remote switch. If the
door switch circuit is open or the door is opened while the remote control mode is active ”door OPEn” is
displayed and the control unit returns into standby mode.
Memory for power failures: the control unit resumes operation if the remote switch has remained in ON
position.
Preset time: if the control unit is on preset delay time, it cannot be controlled with a remote switch. After
the preset delay has passed and the heater is turned on, it can be turned off with a remote switch.
Dehumidifying: when the heater is turned off remotely and dehumidifying is enabled, dehumidifying starts
and cannot be stopped remotely. When dehumidifying is in progress and a safety switch is used, the heater
can be turned on remotely. If a door switch is used, the heater cannot be remotely started, as the remote use
mode must be re-activated by pressing and holding the control unit’s heater button for three seconds.
Power saving mode: If no buttons are pressed in 30 minutes, power saving mode is
activated. Only the heater button (and ”rc on”, if remote use mode is active) is lit.
Pause time: When the heater is switched off, status message rESt appears on the
control panel display. This feature prevents the heater from turning on automatically
during a timed start or weekly clock if it has been less than 6 hours since the
heater was last turned off.
FOTA (Firmware Over the Air)
The Xenio WiFi control panel has a feature that automatically downloads the latest
firmware to the control panel.
