5.10. Connecting the safety shut-off/door sensor

EN 60335-2-53 states that sauna control units with a remote control function may
only be used for controlling a sauna heater which has satisfied the combustion
test in section 19.101. Alternatively, a suitable safety shut-off / door-open sensor
can be installed. This shuts the sauna heater off if items (such as a towel) are
placed on the sauna heater or the sauna door is opened.
To install the safety shut-off device, perform the following steps:
1. Install the safety shut-off device in accordance with the operating instructions
for the device.
2. Feed the cables for the safety shut-off through the cable gland 6 into the
low-voltage connection area 1.
3. Connect the cables to the terminals labelled "OSG" in terminal strip 2.
If a safety shut-off is not installed, a jumper must be fitted at the terminals
labelled "OSG".

5.11. Remote start

The remote start device is connected using terminals "S", "B" and "C". "S" stands for
sauna mode and "C" for vaporizer mode. "B" is a +24 V DC output. The preferred
operating mode must be activated using a switch or actuator on the terminal.

5.12. Status output

Any electrical device can be connected to the status output terminal which is
suitable for 24 V DC voltage and draws a current no greater than 200 mA. Make
sure the polarity is correct when connecting a device. If LEDs are used, a suitable
series resistor must be used.

5.13. Finishing the installation

1. Connect the protective earth conductors for the power supply cable and all
devices to the earthing bar g.
2. Place the cover of the housing on the upper edge of the junction box.
3. Push the clip locks inwards lightly, and turn the cover of the housing down-
wards until it engages audibly.
