Operating Instructions

RDF600KN

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

+ / –

Press + or – to increase or decrease the current room temperature setpoint for Comfort mode. The thermostat changes to Comfort

The setting range is 5...40 °C, unless limited by parameters P09 and P10.

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 setpoint 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

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 protection 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.

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

Recalibrating the sensor

* Needs to be configured by your HVAC installer

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!

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"

If the room temperature displayed by the thermostat does not agree with the

erature effectively measured (after min 1 hour of operation), the tem-

temp 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.

Control parameters

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

+ / – 1. Press the – and + buttons simultaneously at least 4 seconds.

Release, and within 2 seconds, press + again until "P01" is displayed.

2. Repeatedly press the + or – button to select the required parameter.

+-+

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.
