Display (ETD) control connection
6.3
The ETD control must be connected to the controller with a shielded twisted-wire pair cable of 100 m max
length. Use one of the available sockets to connect inside the unit’s interior.
The ETD control is IP20 ; it is reserved exclusively for an indoor usage sheltered from moisture.
It is equipped with an internal temperature probe.
In case of an outdoor mounting of the RHE unit OI, you can also leave it inside the housing of the
electrical box. Once the parameter setting is done, the remote control can be disconnected.
