2.8 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.

2.9 LocatRemote 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 when using a Trend controller.
The maximum length of an AWG 26 cable is 130 m when using a Trend controller.
