5.10. Connecting the safety shut-off

EN 60335-2-53 states that sauna control units with remote control may only be
used for operating and regulating a sauna heater which has satisfied the combus-
tion test described in paragraph 19.101. Alternatively, a suitable safety shut-off
device can be installed in or above the heater. This shuts the sauna heater off
when objects, e.g. a towel, are placed on the sauna heater.
To install the safety shut-off device, perform the following steps:
1. Install the safety shut-off device in accordance with the operating instruc-
tions for the device.
2. Guide the wires for the safety shut-off device through the cable bushing 6
into the low-voltage connection area 1.
3. Connect the wires for the temperature sensor 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 evaporator mode. "B" is a +24 V DC output. The
preferred operating mode must be activated using a switch or actuator on the
terminal.
