It is possible to set different parameter values in a para-

troller. You change parameter values with the INCREASE
and DECREASE buttons and confirm 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 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.
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 setting in the display.
