Siemens RDF301, RDF301.50..., RDF600KN, RDF600KN/VB, RDF600KN/S CE1N3171en
Smart Infrastructure Semi flush-mount communicating room thermostats 2020-02-21
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-speed 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 (standard presence and hotel presence)
· 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.
* On RDF301 and RDF301.50, it is recommended that the fan is running in
deadzone, i.e. P60=0, or using a return air- or external temperature sensor.
RDF301.50, RDF600KN/S 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).
