RDG – the electronic room thermostat that allows you to set the ideal room temperature you want.
The thermostat satisfies your individual needs in all operating modes: Comfort, Economy and
Protection. 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
 The room temperature setpoint can be adjusted with the rotary knob when
Comfort mode is active
 Turn the rotary knob clockwise (+) to increase, or counterclockwise (-) to
decrease the current room temperature setpoint for Comfort mode
The setting range is from 5...40 °C, unless limited by parameters P09 and P10 (for parameter
settings, see reverse side).
Adjusting the fan speed
 Press the fan mode button 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. When the room
temperature reaches the setpoint, the fan stops (factory setting) or runs at low
speed (P15).
 In Manual mode, the fan operates independently and always runs at the same
speed: Low / medium / high
Note:
If desired, you can change the fan mode selector option via P03: Manually only, or manually including
Protection mode. Use P15 to set the fan speed in dead zone.
Selecting Comfort mode
 Press the operating mode button until symbol appears, indicating that
Comfort mode is selected
 In Comfort mode, the thermostat maintains the setpoint which can be readjusted
with the rotary knob
Selecting Protection mode
 Press the operating mode button until symbol appears, indicating that
Protection mode is selected
 In Protection mode, the plant stops operating. If the room temperature falls
below 8 °C, heating is switched on however 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
Selecting Economy mode
In Economy mode, the room temperature is maintained at a lower or higher setpoint, thus saving
energy and money.
 When selecting Economy, make sure that parameter P02 is set to 2
 Press the operating mode button until symbol
appears
 You can change the preselected setpoint by adjusting parameters P11 and P12
(for parameter settings, see reverse side)
Important: The setpoint for Economy can be set to OFF. This means that the thermostat is deactivated!
Risk of frost, i.e. no protective heating or cooling function is provided!
Energy saving tips without sacrificing comfort:
• Air out rooms for short periods of time only, but properly, with the windows wide open
• Never allow the room temperature to exceed 21 °C through heating, and to fall below 25.5 °C through cooling
Button lock
 To lock or unlock the buttons manually, press and hold the fan mode button for
3 seconds. The buttons are locked or unlocked in this manner if P14 is set to 2
 If P14 is set to 1, the thermostat automatically locks the buttons 10 seconds after
the last adjustment
