Damage to the device: do not install the control unit wtih a cordless screwdriver!
Risk of breakage!

Terminal X1:
INPUT: mains supply line. The fuse must be positioned externally in accordance with Figure 3
OUTPUT: connection load: 230V AC1
ENABLE: enable input
Connector X2: operating unit connection.
2.3.2 Connection of the STL (safety temperature limiter) –
signals of a sauna control unit
This is an indirect STL. Devices which are not inherently safe must not be operated on
the switchbox.
The STL signal can be incorporated via the ENABLE input of the switchbox. When 230V is exerted on ENABLE,

2.3.3 Remote start of sauna and infrared devices with potential­free remote
start contact (Fig.

)
For devices without 230V remote start input, the remote extension WC4­SB­REM is necessary.
Where sauna heating devices are directly operated on the switchbox, it must be ensured that
they are inherently safe. The switchbox has no safety temperature restriction.
