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 nor-
mal control occurs automatically when condensation ceases.

The display has the following indications:

Buttons
RC-DTO has the following buttons:
• Occupancy button
When the Occupancy button is held depressed for more than 5
setpoint in steps of 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
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.
• INCREASE button
• DECREASE button
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 parame-
ters by using the INCREASE and DECREASE buttons.
Occupancy
Press the Occupancy button to select the desired parameter. The para-
indication
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

perature in °C to

Acknowledge/Regret change
To acknowledge and store a set parameter value, press the Occupancy
Open window
button again, the display then returns to showing the parameter number.
To retrieve the original value, i.e. the value before change, press the IN-
CREASE 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 DECREASE
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 parameter 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.
