Operating Instructions
RDF301, RDF301.50
RDF301 / RDF301.50 – the room thermostat with KNX communications allows you to set the ideal room temperature.
The thermostat provides Comfort, Energy Saving, 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.

Notes:
– The thermos tat goes back to Auto
Timer mode if a time schedule via
bus changes the operating mode.
– User operations are ignored if a
time schedule via bus sets the
operating mode to protection.
When you press a button, "OFF"

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 continues to run at low speed
(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
For a 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 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 Energy Saving 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 Energy Saving 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 Energy Saving 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).

to temporarily return to Comfort mode.
symbol appears. Press opera-
ting 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.
Operate switching groups
Use buttons I, II, III and IV to operate KNX actuators *.
The following functions are available:
– Switching: Toggle on/off with 1 button or on/off with 2 buttons
(I + II or III+IV). "ON" or "OFF" is displayed.
– Dim lights with 2 buttons (I+II or III+IV):
On/off with a short pulse (<0.5 s); "ON" or "OFF" is displayed.
Brighter/darker with a long pulse (>1 s); "dI" is displayed.
– Operate blinds with 2 buttons (I+II or III+IV):
A long pulse (>1 s) starts the up/down motor; "UP" or "down" is displayed.
A short pulse (<0.5 s) stops the motor or slightly adjusts the position of
blinds; "ON" or "OFF" is displayed.
– Scene I, II, III, or IV: A scene can be used to recall certain states of all
actuators involved, as well as to save new states as needed. E.g. different
dimmed lights and blinds positions you consider adequate for certain
events / times.
A short pulse (<0.5 s) starts the scene. "CALL" is displayed.
A long pulse (>3 s) saves the actual position of all actuators involved as
adjusted previously; "SAVE" is displayed.
Button lock
Press operating mode button
for 5 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

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: Energy saving mode
The energy saving 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!
* Needs to be configured by your HVAC installer
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 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 3 seconds.
Release, and within 2 seconds, press + again for 3 seconds. "P01" is displayed.
