Operating InstructionsRDF600KN

RDF600KN ??? the room thermostat with KNX communications allows you to set the ideal room temperature.

The thermostat provides Comfort, Economy, and Protection mode and can operate in Auto timer mode using a time schedule provided via bus.

The fan operates either in Auto mode or at a speed selected in Manual mode.

You can either take advantage of the thermostat's factory settings or adjust it as needed.

Change room temperature

Adjust fan speed / fan mode

Press the button until you reach the desired fan mode.

In Auto mode, the thermostat automatically selects the fan speed based on set- point and actual room temperature. The fan is switched off (factory setting) after the room temperature reaches the setpoint .

In manual mode, the fan always runs at the speed that you select: Low fan speed

Medium fan speed High fan speed

Single-speed fan: You can change the mode between and .

Change thermostat operating

Press operating mode button to change the operating mode display.

In protection mode, the plant stops operating. However, if the room temperature drops below 8 ??C, heating is switched on to protect the room against frost.

Your HVAC installer can change the frost protection limit and set a heat pro- tection limit as needed:

Changes made by installer: ??? Frost protection: ........... ??C Heat protection: ........... ??C

In Comfort mode, the thermostat maintains the room temperature on the setpoint which can be readjusted using the + and ??? buttons.

In Economy mode, the room temperature is maintained at a lower or higher setpoint, thus saving energy and money. Adjust parameters P11 and P12 to change the preselected setpoints.

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 contact, keycard or presence detector.

In Auto timer mode, the thermostat automatically switches between Comfort and Economy mode according to the time schedule via KNX bus.

Change from heating to cooling mode

cooling only or heating only, (see parameter P01).

Display for automatic changeover or heating only / cooling only:

Heating valve is open

Cooling valve is open

Display for manual changeover:

Temporary timer to extend the Comfort mode

When Economy mode is active, press operating mode button to tempo-

rarily return to Comfort mode. symbol appears. Press operating mode button again to stop the timer.

You can only extend Comfort mode if parameter P02 = 1. Duration * : P68 = 0...360 min, factory setting = 0 min.

Button lock

Press operating mode button for 3 seconds to lock or unlock the buttons if

manual button lock is configured (parameter P14 = 2).

The thermostat automatically locks the buttons 20 seconds after the last adjustment if "Auto lock" is configured (P14 = 1).

The key symbol indicates locked buttons.

Reminder to clean filters and for external faults

FIL * This message reminds you to clean your HVAC equipment filters.

It is displayed after ??????????????? ???fan operating hours??? and disappears when the thermostat is set to Protection ().

Note: Economy mode

The Economy setpoints are factory-set to 15 ??C for heating and 30 ??C for cooling. Use parameters P11 and P12 to adjust the values.

Important: You can set these setpoints to OFF; the thermostat then is inactive, i.e. no protective heating or cooling function.

Risk of frost!

Commissioning

You can adjust a number of different control parameters to adapt the thermostat to your system and optimize control performance. You can do this during operation either via the buttons on the thermostat or using a commissioning tool.

Control sequence

The thermostat can be used in systems either for heating only or cooling only, manually selection of heating or cooling, or automatic heating / cooling changeover. Depending on the selected application, the relevant modes are available and can be adjusted by commissioning parameter P01 if needed.

The factory setting for 2-pipe application is "Cooling only", and for 4 pipe application "Heating and Cooling"

Recalibrating the sensor

If the room temperature displayed by the thermostat does not agree with the temperature effectively measured (after min 1 hour of operation), the tem- perature sensor can be recalibrated. With parameter P05 the temperature can be adjusted by + or ??? 0.5 ??C up to a maximum of + / - 3 ??C.

* Needs to be configured by your HVAC installer

Control parameters

Proceed as follows to change the most important control parameters: (Your HVAC installer can set additional parameters)

3.Press + and ??? simultaneously. The current value of the selected parameter begins to flash, allowing you to change the value by repeatedly pressing + or ???.

4.The next parameter is displayed when you press + and ??? again simultaneously.

5.Repeat steps 2 to 4 to display and change additional parameters,.

6.Press + or ??? until ???End??? is displayed, and then press + and ??? simultaneously to save the change and exit parameter entry mode.

15 minutes after the last display or setting, all changes are saved and the thermostat leaves parameter setting mode.
