Building Technologies

Additional RDF600KN features:

• Independent function for window contact and presence detector
Additional RDF301.50 features:

• Four buttons to control KNX actuators via KNX S-mode

(functions: switching, dimming, blinds control, 8-bit scene)

Additional RDF301.50H features:

• Four buttons for hotel functions MUR (Make Up Room), DND (Do Not

Disturb) via KNX S-mode

Type of mounting / suitable conduit boxes:

• RDF600KN for round box, with min 60 mm diameter, min 40 mm depth

and recessed rectangular box with 60.3 mm fixing centers

• RDF301... for recessed rectangular box with 60.3 mm fixing centers

Use

Room temperature control (heating or cooling) in individual rooms and zones by
means of:

• 2-pipe fan coil units

• 2-pipe fan coil units with electrical heater

• 4-pipe fan coil units

• Compressors in DX-type equipment

• Compressors in DX-type equipment with electrical heater

The RDF301... / RDF600KN controls:

• One single or 3-speed fan

• One or two on/off valve actuators

• One on/off valve actuator and one 1-stage elec tr ic al h eater

• One 3-position valve actuator

• One 1-stage compressor in DX-type equipment, or one 1-stage compressor with

electrical heater

Used in systems with:

• Heating or cooling mode

• Automatic heating/cooling changeover

• Manual heating/cooling changeover

• Heating and cooling mode (e.g. 4-pipe system)

The room thermostats are delivered with a fixed set of applications.
The relevant application is selected and activated during commissioning using one
of the following tools:

• Synco ACS

• ETS

• Local DIP switch and HMI

Functions

• Room temperature control via built-in temperature sensor or external room
temperature / return air temperature sensor.

• Changeover between heating and cooling mode (automatically via local sensor
or bus, or manually).

• Selection of applications via DIP switches or commissioning tool.

• Selection of operating mode via operating mode button on the thermostat.

• Temporary Comfort mode extension.

• 1- or 3-speed fan control (automatically or manually).

• Display of current room temperature or setpoint in °C and/or °F.

• Minimum and maximum limitation of room temperature setpoint.

• Button lock (automatically and manually).

• 2 multifunctional inputs, freely selectable for:

− Sensor for automatic heating / cooling changeover

− External room temperature or return air temperature sensor

− Dew point sensor

− Electric heater enable

− Fault input

− Monitor input for temperature sensor or switch state

RDF301…:

− Operating mode switchover contact … (keycard, window contact, etc )

RDF600KN:

− Window contact

− Presence detector

• Advanced fan control function, e.g. fan kick, fan start, selectable fan operation

(enable, disable or depending on heating or cooling mode).

• Purge function together with 2-port valve in a 2-pipe changeover system.

• Reminder to clean fan filters (adjust with P62).

• Floor heating temperature limitation.

• Reload factory settings for commissioning and control parameters.

• KNX bus (terminals CE+ and CE-) for communication with Synco or KNX

compatible devices.

• Display of outdoor temperature or time of day via KNX bus.

• Time scheduling and central control of setpoints via KNX bus.

• With a Synco RMx7xx controller, the energy demand signal of the thermostat is

used to optimize energy supply.

RDF301.50 only:

• Four buttons to control KNX actuators via KNX S-mode.
("switching groups" with functions such as switching, dimming, blinds control,
8-bit scene).

RDF301.50H only:

• Four buttons for Hotel applications to control via KNX S-mode.
Same functions as RDF301.50, but with dedicated button labels for hotel
applications: Make Up Room (MUR), Do Not Disturb (DND).

Applications

The thermostats support the following applications, which can be configured using
the DIP-switches on the inner side of the thermostat's front panel or a commissio­ning tool.

All DIP switches need to be set to OFF (remote configuration, factory setting) to
select an application via commissioning tool.

Remote configuration
