Installation
The room unit is installed indoors on a wall, using the mounting holes on
the back plate. It is to be installed on an EU standard wall mounting box
as the terminal block stands out a few millimetres from the back plate.
N N o o t t e e ! ! The display is pre-configured upon delivery and can therefore be
used directly together with Regin's room controllers. When used with
other controllers, the communication settings might need to be changed
in the Firmware configuration menu (see Table 1).
Wiring
Depending on the used controller there are two different wiring options:
– Option 1: The room unit is connected via a EDSP-K3 cable to the
controller's display port.
– Option 2: The room unit is connected to the controller's serial port.
The supply voltage is connected to the same supply voltage as the
controller (G and G0).
