Siemens RDF301. / RDF301.50 / RDF600KN CE1N3171en
Building Technologies Semi flush-mount room thermostats with KNX communications 2012.10-04
 Two multifunctional inputs, freely selectable for:
 Operating mode switchover contact (keycard)
 Automatic heating/cooling changeover sensor
 External room temperature sensor or return air temperature sensor
 Dewpoint sensor
 Electrical heater enable
 Fault input
 Monitor input for temperature sensor or switch status
 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 filters
 Floor heating temperature limit
 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)
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 commissio-
ning tool.
All DIP switches need to be set to OFF (remote configuration, factory setting) to
select an application via commissioning tool.
