Operating mode
There are five different operating modes. Switching between these
modes is performed locally.
Stand-by: Both heating and cooling are disconnected within a tem-
perature interval around the applicable setpoint (FS = heating setpoint
value - 3°C, cooling setpoint + 3°C).
Occupied: The room temperature is controlled according to the ap-
plicable cooling setpoint (FS = 24°C) or heating setpoint (FS = 22°C).
Bypass: Is controlled by the occupancy detector or other digital
contact connected to the controller, closing activates Bypass. Control
of the room temperature in the same way as Occupied mode. Bypass
also controls forced ventilation. Reset to Preset operating mode
occurs after a certain time (FS = 10 minutes) of non-occupancy (no
signal from presence detector).
Unoccupied: Both heating and cooling are disconnected within a
temperature interval with configurable min/max limits (FS = min 15°C,
max 30°C). This mode is activated when the Occupancy button is
held depressed for more than 5 seconds.
Off: Heating and cooling are disconnected. However, the temperature
must not drop below the set minimum temperature (FS=8°C). The
mode is activated on open window (or when the Occupancy button is
held depressed for more than 5 seconds, if this has been configured
in the parameter menu).
Preset operating mode
Occupied is the preset operating mode. This can be set to Stand-by in
the parameter menu, parameter 45.
Occupancy detector
An occupancy detector is connected for local control of the operating
mode between Preset operating mode and Bypass.
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
0.5°C up to the max. limit (+3°C). Pressing on DECREASE decreases
the current
setpoint in steps of 0.5°C down to the min. limit (-3°C).
Switching between heating and cooling setpoints is done automatical-
ly in the controller depending on the heating and cooling requirement.
Choice of setpoint display, see parameter 74.
Frost protection
Independent of the operating mode, the heating control is forced on
when the room temperature drops below 8°C (FS). Return to normal
control occurs automatically when the room temperature exceeds
8°C.
Condensation detector
If there is condensation, the cooling control is blocked. Return to
normal control occurs automatically when condensation ceases.
Display handling
Indications
The display has the following indications:
Setpoint
Indoor /
outdoor temp.
OFF: Unoc-
cupied (also
shows tempe-
rature) or Off
indication
(only OFF)
Buttons
RC-DO has the following buttons:
•
Occupancy button
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". The factory setting is that Unoc-
cupied is activated.
If you press the Occupancy button for less than 5 seconds when the
controller is in operating mode Shutdown or the preset operating
setpoint in steps of
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. After a
configurable time in Bypass (FS = 2 hours), the controller returns to
the preset operating mode.

Setting parameters
Change parameters
It is possible to set different parameter values in a parameter menu. The
parameter menu is accessed by simultaneously holding the INCREASE
and DECREASE buttons depressed for about 5 seconds and then pressing

the INCREASE button twice. The Service indication will be displayed.
First the display will show the parameter-number 1. Scroll between
parameters by using the INCREASE and DECREASE buttons.
Press the Occupancy button to select the desired parameter. The para-
meter number will be replaced by the parameter value. The value can
be changed using the INCREASE and DECREASE buttons. If a button
is held depressed the value will start scrolling, first slowly and then with
increasing speed in 3-4 steps with 2-3 seconds between steps.
Acknowledge/Regret change
To acknowledge and store a set parameter value, press the Occupancy
button again, the display then returns to showing the parameter num-
ber. To retrieve the original value, i.e. the value before change, press
the INCREASE and DECREASE buttons at the same time. The original
value is shown on the display.
Return to normal display
After a certain time, about 1 minute, or when the INCREASE and DE-
CREASE buttons are pressed at the same time while in the menu, the
display returns to the normal view.
Exit is shown on the display after the last parameter. The parame-
ter menu is exited by pressing the Occupancy button while in Exit.
Pressing on INCREASE goes to the first parameter and pressing on
DECREASE goes to the last parameter.

The following parameters can be changed in the parameter menu:
