4.1 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 in a clean, dry indoor place without direct airflow
from a heating / cooling device, and not exposed to dripping or splash water
Wiring See Mounting Instructions M3191 [3] 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
 Inputs 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 AC 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
