Siemens RDG100KN Room thermostat with KNX communications CE1N3191en
Building Technologies 01 Jun 2010
Engineering notes
See the "Reference documentation", page 12 for information on how to engineer
the KNX bus (topology, bus repeaters, etc.) and how to select and dimension
connecting cables for supply voltage and field devices.
Mounting and installation
Do not mount on a wall in niches or bookshelves, behind curtains, above or near
heat sources, or exposed to direct solar radiation. Mount about 1.5 m above the
floor.
Mounting
 Mount the room thermostat on a clean, dry indoor place without direct airflow
from a heating / cooling device, and not exposed to drips or splash water.
Wiring
See the mounting instructions M3191 enclosed with the thermostat.
 Comply with local regulations to wire, fuse and earth the thermostat.
 Properly size the cables to the thermostat, fan and valve actuators for AC 230 V
mains voltage.
 Use only valve actuators rated for AC 230 V.
 The AC 230 V mains supply line must have an external fuse or circuit breaker
with a rated current of no more than 10 A.
 Isolate the cables of input D1-GND for 230 V if the conduit box carries AC 230 V
mains voltage.
 X1-M,X2-M or D1-GND: several switches (e.g. summer/winter switch) may be
connected in parallel. Consider overall maximum contact sensing current for
switch rating.
 Inputs X1-M and X2-M carry mains potential.
Sensor cables must be suited for AC 230 V mains voltage
 Isolate the cables of KNX communication input CE+ / CE- for 230 V if the conduit
box carries AC 230 V mains voltage.
 No cables provided with a metal sheath.
 Disconnect from supply before removing from the mounting plate.
