RDG160KN
RDG100KN / RDG160KN – the room thermostat with KNX communications that allows you to set the
ideal room temperature you want. The thermostat provides Comfort, Economy and Protection mode.
In addition it can operate in Auto timer mode according to a schedule via KNX bus.
The fan operates either in Automatic mode or at the selected speed when using Manual mode.
You can either rely on the factory settings or make adjustments that suit your individual needs.

Changing the room temperature
Turn the rotary knob clockwise (+) to increase, or counterclockwise (-) to decrease
the current room temperature setpoint. The thermostat changes to Comfort .
The setting range is from 5...40 °C; it can be limited by parameters P09 and P10.
(for parameter settings, see reverse side).
Adjusting the fan speed
Low Medium High
Press the right button repeatedly until the desired fan mode is reached.
In Automatic mode , the fan speed is automatically selected by the thermostat
depending on the setpoint and the actual room temperature.
RDG100KN: When the room temperature reaches the setpoint, the fan keeps
running at low speed (factory setting).
RDG160KN: The fan stops (factory setting) or keeps running at low speed (P15).
In Manual mode, the fan operates independently and always runs at the speed
you set: low / medium / high.
Note:
If desired, you can change the fan mode selector option via P03: Auto / manual, Manual only, or
Manual including Protection mode.
Changing the operating mode of the thermostat
Press the operating mode button repeatedly until the s
y
mbol points to the operatin
g
mode you desire.
1. Protection mode
In protection mode, the plant stops operating. However, if the room temperature
falls below 8 °C, heating is switched on to protect the room against frost.
The setpoints for Protection mode can be changed by your HVAC installer if desired:
Changes made by installer: Frost protection: _________ ˚C Heat protection: __________˚C
2. Comfort mode
In Comfort mode, the thermostat maintains the room temperature on the setpoint
which can be adjusted with the rotary knob
3. Auto Timer mode
In Auto Timer mode, the thermostat automatically switches over between Comfort
and Economy mode according to the schedule via KNX bus.
If no schedule via KNX is available, then Auto Timer is replaced by Comfort.
4. Economy mode
In Economy mode, the thermostat maintains the room temperature at a lower or
higher setpoint, thus saving energy and money.
The thermostat can be set to Economy mode either by pressing the operating
mode button if enabled (P02 = 2), or via an external signal (switch or KNX bus
command) such as window switch, keycard or presence detector.
The Economy setpoints are factory-set to 15 °C for heating and 30 °C for cooling.
They can be adjusted via parameters P11 and P12 (for parameter settings, see
reverse side).
Important: These setpoints can be set to OFF; which means that the thermostat
is not active., i.e. no protective heating or cooling function. Risk of frost!
Changing from heating to cooling mode
The changeover from heating to cooling (or vice versa) is made
–either automatically by a changeover sensor, or a changeover switch, or a
remote changeover switch via KNX command
–or manually by pressing the operating mode button.
If the thermostat is configured for "heating only" or "Cooling only", changeover is
not available (see parameter P01)
To select cooling or heating manually (P01=2), press the operating mode button
until the symbol points to the mode you desire.
With automatic changeover or continuous heating / cooling, symbols
indicate that the system currently heats or cools.
With manual changeover, symbols indicate that the system currently
operates in heating or cooling mode. Symbols indicate that the system
currently heats or cools.

Timer to extended presence or absence
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.

Locked buttons are indicated with the key symbol
If "Auto lock" is configured (P14 = 1), the thermostat will automaticall

buttons 10 seconds after the last adjustment.
Commissioning (by qualified HVAC installer)
To adapt the thermostat to
y
our s
y
stem 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 thermo-
stat 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 chan
g
ed
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.
