RU-DO is a room unit from the Regio series with
display. It should be connected to one of the Regio Maxi
controllers RCP100, RCP100T, RCP200 or RCP200T.
Regio
Regio is a wide series of controllers which handle heating
and cooling.
The controllers are divided into three different series,
Mini, Midi and Maxi. Mini are pre-programmed,
stand-alone controllers. The Midi controllers are pre-
programmed with communication. The Maxi group, to
which RU-DO belongs, consists of freely programmable
controllers with communication.
Applications
The Regio controllers are suitable in buildings where you
want optimal comfort and low energy consumption, for
example ofces, schools, shopping centres, airports, hotels
and hospitals etc.
Design
The room units have a modern design. The
design has been awarded the 2007 “iF product
design award”.
Sensor
The room unit has a built-in sensor.
Easy to install
The modular design with a separate bottom plate for
wiring makes the whole Regio series easy to install and
commission. The bottom plate can be put into place
before the electronics are installed. Mounting is directly
on the wall or on an electrical connection box.
Connection to RCP
The room unit is connected to the RCP-unit with an
RJ12-cable, max length 30 m. Regin has two cables as
accessories, RU-CBL3 (length 3 m) and RU-CBL10
(length 10 m).

Display handling
The display has the following indications:
It is possible to set different parameter values in a
parameter menu in the display, using the buttons on
the controller. You change parameter values with the
INCREASE and DECREASE buttons and conrm
changes with the Occupancy button.
The Occupancy button
If you press the Occupancy button for less than 5
seconds when the controller is in the preset operating
mode (Occupied or Stand-by), the controller changes to
operating mode Bypass. It will automatically return to the
preset operating mode after a congurable time (FS=2
hours). If you press the button for less than 5 seconds
when the controller is in Bypass, it changes operating
mode to the preset operating mode.
When the Occupancy button is held depressed for more
than 5 seconds, the controller changes operating mode to
”Shutdown” (Off/Unoccupied), regardless of the current
operating mode. Via the display, you can congure which
operating mode, Off or Unoccupied, should be activated
on ”Shutdown” (FS=Unoccupied). If you press the
Occupancy button for less than 5 seconds in Shutdown,
the controller returns to Bypass.
Forced ventilation
Regio has a built-in function for forced ventilation.
A short press on the Occupancy button activates the
output that has been congured for forced ventilation, for
example for a damper.
Setpoint
In Occupied mode, the controller operates from a heating
setpoint (FS=22°C) or a cooling setpoint (FS=24°C) that
can be changed using the INCREASE and DECREASE
buttons.
Pressing on INCREASE increases the current setpoint by
0.5°C with each press up to the max. limit (FS = +3°C).
Pressing on DECREASE decreases the current setpoint by
0.5°C with each press down to the min. limit (FS = -3°C).
Switching between heating and cooling setpoints is done
automatically in the controller depending on the heating
and cooling requirement.
