2.18. Door switch

The door switch refers to the switch on the sauna door. This switch complies with regulations. Public and private saunas
must have a door switch, i.e. saunas where the heater can be switched on from outside the sauna, e.g. using an On/Off
button or a similar method.
If the door is opened before the heating sequence is started, (pre-set heating) automatic use (remote use) is disabled after
one minute. The door must be closed and the function restarted from the control panel.
If the door has been left open for more than five minutes while the heater is on, the heater is automatically turned off.
The heater can be turned on again from the control panel after the door is closed. The fault indicator light, if installed, will
start flashing. See installation instructions below.
Door switch instructions for installation and connection
The door switch is installed outside the sauna room on the upper edge of the door, at least 300 mm from the inner corner.
The switch part is installed on the door frame and the magnet is installed on the door. The distance between the switch and
