Operating Instructions

Timer to extended presence or absence (RDG1..0KN only)
The Comfort and Economy modes can be temporarily extended by 0.5 to 9.5 hours using the timer.
1. To set the timer, press and hold the operating mode button.
While holding the button, turn the rotary knob clockwise or counterclockwise as required.
a) Turn the rotary knob clockwise to extend Comfort mode.
Display:
0...+9:30
b) Turn the rotary knob counterclockwise to extend Economy mode.
Display:
0...–9:30
2. Release the operating mode button and the mode is temporarily changed, indicated by
symbol.
•
After the temporary timer has elapsed, the thermostat will resume operation in the operating mode
according to schedule via bus (if available). Without schedule:
– when extended Comfort mode ends  new operating mode = Economy
– when extended Economy mode ends  new operating mode = Comfort
•
If Economy mode cannot be selected via the operating mode button (P02 ≠ 2), Protection mode will
be used for extended absence instead.
•
The temporary timer function is aborted whenever a new setting is made.
Temporary timer to extend the Comfort mode
When the operating mode is Economy (commanded by schedule via KNX or by en external signal. e.g.
keycard)
, it can be set back to Comfort temporarily by pressing the operating mode button.
The symbol will appear.
Pressing the operating mode button again will stop the timer.
This function is only available when parameter P02 = 1. Duration: * P68 = 0...360 min, factory setting = 0 min.
* Needs to be configured by your HVAC installer.
Humidity control (RDG165KN only)
Humidity in the room is controlled by shifting temperature setpoint and release of external equipment
(dehumidifier / humidifier). When the relative humidity in the room exceeds the limitation (max. or
min.), the
symbol displays and the thermostat controls the humidity in the room.
•
Set the maximum humidity limitation via P21; Set the minimum humidity limitation via P22.
•
Relative humidity value (% r.H) displays when P07=5 (factory setting).

Commissioning (by qualified HVAC installer)
To adapt the thermostat to your system and optimize the control performance, a number of control
parameters can be adjusted. This can be done during operation, either via the buttons on the
thermostat or via a commissioning tool.
Control parameters
If you wish to change control parameters, proceed as follows:
1. Press left and right buttons simultaneously for at least 4 seconds.
2. Release them and, within 2 seconds, press the right button again until "P01" is displayed.
3. Select the required parameter by turning the rotary knob.
4. Press button
(OK). The current value of the selected parameter starts blinking
and can be changed
by turning the rotary knob.
5. Press button (OK) to confirm the adjusted value, or (Esc) to cancel the change.
If you wish to adjust additional parameters, repeat steps 3 through 5, or press (Esc) to leave the
parameter setting mode.
