RU-FO is a room unit from the Regio series. It has a
switch for controlling a three-speed fan (fan coil). It
should be connected to one of the Regio Maxi controllers
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-FO 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).

Regin product information
The Occupancy button
If you press the Occupancy button for less than 5 seconds
when the controller is in the preset operating mode, the
controller changes to operating mode Bypass. 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
Unoccupied, regardless of the current operating mode. If
you press the Occupancy button for less than 5 seconds
in Unoccupied, 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 centrally or locally using the dipswitches
on RU-FO.
The setpoint can be adjusted up and down
(FS=+/-3°C) with the knob on the front of the room unit.
Switching between heating and cooling setpoints is done
automatically in the controller depending on the heating
and cooling requirement.
Indications
The room unit has an LED shaped like a thermometer on
the front. A red indication is shown when heating control
is functional and a blue indication when cooling control is
active. No LED indication shows that neither heating nor
cooling control is active.
Fan control
RU-FO has a fan switch with the following positions:
Auto Automatic control of the fan speed to maintain
desired room temperature.
0 Fan off.
I Manual 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 position of the fan switch.
