2.12. Locating the connecting box for the connection cable in the sauna room
A = Specified minimum safety clearance
1. Recommended location for the connecting box
2. Silumin box recommended in this area.
3. This area should be avoided. Always use a silumin box.
In other areas, use a heat-resisting box (T 125 °C) and heat-resisting cables (T 170 °C). The connection box must be
clear of obstacles. When installing the connection box to zones 2 or 3, refer to the instructions and regulations of the
local energy supplier.
Figure 4 Location for the connection box
2.13. Remote controlling
The Heater can be remotely controlled by connecting a closed contactor, which can be pulse triggered, to connectors 3
and 4 of a RJ10 circuit board. The recommended cable size is AWG 24 or 26. The maximum length of an AWG 24
cable is 200 m.
The maximum length of an AWG 26 cable is 130 m.
Note! The sauna standard requires a door switch if the sauna heater is controlled from outside the sauna.
An indicator light can be connected to the remote button terminal, it will be lit up when the remote command is activated.
The indicator light shows an error by blinking rapidly, this error is caused by keeping the sauna door open for more than
5 minutes, the sauna heater will be shut down automatically.
The remotely operated sauna heater stays on as long as the setting in the control panel (in private us max 6h). The
sauna heater can be shut off at any time by the remote-control device.
