with Regio Maxi controllers. 9Simple installation

9Backlit display
9Cable for connection between the room
unit and the RCP controller is available as

Function
RU-DFO is a room unit from the Regio series with display
and fan button for controlling a three-speed fan (fan coil).
It should be connected to one of the Regio Maxi control-
lers RCP100F, RCP100FT, RCP200F or RCP200FT.
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-DFO 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 offices, schools, shopping centres, airports, hotels
and hospitals etc.
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 be-
fore 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).

It is possible to set different parameter values in a para-
meter menu in the display, using the buttons on the con-
troller. You change parameter values with the INCREASE
and DECREASE buttons and confirm changes with the
Occupancy button.

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 opera-
ting mode Bypass. It will automatically return to the pre-
set operating mode after a configurable 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 configure 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 configured for forced ventilation, for exam-
ple 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.
Fan control
RU-DFO has a fan button. When you press the button,
a symbol is shown in the display for 10 seconds. During
this time, it is possible to change the fan speed using the
INCREASE/DECREASE buttons.
The controller has the following positions:
Auto Automatic control of the fan speed to maintain
desired room temperature.
0Fan off.
IManual position with low speed.
II Manual position with medium speed.
III Manual position with high speed.
In operating modes Off and Unoccupied, the fan is
stopped, regardless of the setting in the display.
