Operating Instructions

RDF600 – the room thermostat that allows you to set the ideal room temperature you want.

The thermostat provides Comfort mode, Economy mode 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.

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 from 5...40 °C, unless limited by parameters P09 and P10.

Adjust fan speed / fan mode

Set the thermostat to Protection

Set the thermostat to Economy mode

 

Change from heating to cooling mode

Press the button until you reach the desired fan mode.
In Auto mode, the fan speed is automatically selected by the thermostat and

depends on the setpoint and the actual room temperature. When the room
temperature has reached the setpoint, the fan is switched off (factory setting)

In manual mode the fan operates independently and always runs at the same
speed: Low, medium or high.

Low fan speed

Medium fan speed

High fan speed

For a single-speed fan, the mode can be changed between

Press the operating mode button several times until the display shows the

symbol to indicate that Protection is selected.
In Protection

your HVAC installer has adjusted the factory settings.

Changes by installer   Frost protection: ________ ˚C
 Heat protection:

The thermostat can be set to Economy mode either via pressing the operating
mode button

as window switch, key card switch etc.
If the external contact is activated the thermostat changes from Comfort mode or
Protection to Economy mode. Any operation by the user has no influence.

In Economy mode, the automatic fan control is active.

Note: If the thermostat is configured for manual heating / cooling changeover,
the Economy mode can not be selected via operating mode button

The changeover between cooling and heating is done either automatically by a

/

heating / cooling changeover sensor or a remote changeover switch, or manually
by pressing the operating mode button

cooling only or heating only, no changeover is possible (see parameter P01)

The thermostat automatically locks the buttons 30 seconds after the last
adjustment if "Auto lock" is configured (P14 = 1).
The key symbol

indicates locked buttons.

Reminder to clean filters

This message reminds you to clean the filter on your HVAC equipment.

Commissioning (by qualifie

d HVAC installer)
To adapt the thermostat to your system and optimize the control performance, a number
of control parameters can be adjusted. This can also be made during operation without
opening the thermostat.

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
temp

erature effectively measured (after min 1 hour of operation), the tem­perature sensor can be recalibrated. With parameter P05 the temperature can
be adjusted by + or – 0.5 °C up to a maximum of + / - 3 °C.

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!

Control parameters

Proceed as follows to change the most important control parameters:
