Siemens RDF301. / RDF301.50 / RDF600KN CE1N3171en
Building Technologies Semi flush-mount room thermostats with KNX communications 2012.10-04
Additional RDF301.50 features:
 Four buttons to control KNX actuators via KNX S-mode
(functions: switching, dimming, blinds control, 8-bit scene)
Type of mounting / suitable conduit boxes
 RDF600KN for round box, with min 60 mm diameter, min 40 mm depth
 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 electrical heater
 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
 Maintain room temperature via built-in temperature sensor or external room
temperature / return air temperature sensor
 Changeover between heating and cooling mode (automatic via local sensor or
bus, or manual)
 Select application via DIP switches or commissioning tool (ACS, ETS)
 Select operating mode via operating mode button on the thermostat
 Temporary Comfort mode extension
 Single speed or 3-speed fan control (automatic or manual)
 Display current room temperature or setpoint in °C and/or °F
 Minimum and maximum limitation of room temperature setpoint
 Button lock (automatic and manual)
