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 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

/	Changeover between cooling and heating is either automatic using a heating /
	cooling changeover sensor or a remote changeover switch or via instruction from
	the central management station via KNX bus, or manual by pressing operating
	mode button . No changeover is possible if the thermostat is configured for

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