RDG200KN Room Thermostats

Operating Instructions
RDG2..KN – Room thermostat with KNX communications allowing users to set ideal temperature, relative humidity and CO2 level (RDG204KN&RDG264KN). The thermostat offers the operating modes Comfort, Economy and Protection.
In addition, it can operate in Auto mode as per a schedule via KNX bus or local.
The fan operates either in Auto mode or at the selected speed in Manual mode.
Users can either use the factory settings or adjust settings as desired.

• When P002 = 3, the icon is displayed as and the button can be used to switch unit between °C and °F. (scan the above QR code for the latest version info).
  Changing the room temperature
  Turn the rotary knob clockwise to i ncrease, or counterclockwise to decrease the current room temperature setpoint.

Note: The setting range is 5…40 °C; it can be limited by parameters P013 and P016. (for parameter settings, see Control parameters on page 2).

Adjusting the fan speed

• Press the right button repeatedly until the desired fan mode is reached.
• In Auto mode , the fan speed is automatically selected by the thermostat depending on setpoint and current room temperature.
• In Manual mode, the fan operates independently and runs at the speed set by the user: speed I / speed II / speed III.

Changing the operating mode

1. Comfort mode
   • In Comfort mode, the thermostat maintains the room temperature at the setpoint which can be adjusted with the rotary knob.

2. 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 (P002 = 2), or via an external signal (switch or KNX bus command) such as 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 P019 and P020 (for parameter settings, see Control parameters on page 2).

3. Protection mode
   • In Protection mode, the thermostat stops operating. However, if the room temperature drops 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 activated.
   The setpoints for Protection mode can be changed by your HVAC installer if desired:
   Changes made by installer: Frost protection: _____ ˚C Heating protection: __˚C

4. Auto mode
   •  In Auto mode, the thermostat automatically switches over between Comfort and Economy mode as per the KNX bus or local schedule (enabled via P005).
   If no schedule is available, Comfort replaces Auto.

Important: If setpoints are set to Off, there is no protective heating or cooling function. Risk of frost!
Green leaf indication
The green leaf indication is an energy-efficient setting and indicates the end user settings. Green leaf: Settings are within the preset energy-efficient range.
Red leaf: Settings exceed the preset energyefficient range.
End users can press the red leaf and return to the energy-efficient range.
Reminder to clean filter, display of external faults
This message reminds you to clean the filter on your HVAC equipment.
It appears after ___ “fan operating hours” and disappears when the thermostat is manually set to Protection. These fault messages tell you an external fault has occurred :
Needs to be configured by HVAC installer
