RDG405KN
RDG405KN – 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.
You can either rely on the factory settings or make adjustments that suit your individual needs.
Air quality control function is available.

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).
Changing the operating mode of the thermostat
Press the operating mode button repeatedly until the symbol points to the
operating 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 thermostat switches to Protection mode when the window contact (local or
on KNX) is active.
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
•
The thermostat switches to Comfort mode when the presence detector
(local or on
KNX) is active (room is occupied).
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 KNX bus command.
•
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 Not supported with all configurations
•
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.
Fan display
The symbol informs you that the primary fan is active.
Note: Only supported with Synco 700 primary controller.

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.

Indoor Air Quality (IAQ) function
The Indoor Air Quality (IAQ) function is used for air quality control in VAV applications. The function is
achieved by controlling the damp valve position according to the CO2 level of the indoor air as well as
the temperature.
The thermostat monitors the CO2 level via KNX or IAQ
sensors located in the room or in the extract air
duct. If the CO2 setpoint value is exceeded, the thermostat opens the valve in accordance
with the
minimum position, and increases the openness slowly i
f the CO2 level continues rising. When the CO2
level reaches the predefined maximum value, the thermostat opens the valve to the maximum position
until the CO2 level drops.
Note that the valve position is also controlled according to the temperature. It depends on which is higher, the
temperature demand signal or the CO2 level demand signal.
Button lock
•
If the button lock function is enabled (parameter P14 = 2), then pressing the
right button for 3 seconds
will lock or unlock the buttons respectively.
Locked buttons are indicated with the key symbol
•
If "Auto lock" is configured (P14 = 1), the thermostat will automatically lock the
buttons 10 seconds after the last adjustment.
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 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 3 seconds.
2. Release them and, within 2 seconds, press the right button again for 3 seconds.
The display will show P01.
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.
