Mechanical design

The thermostats consist of 2 parts:

•Front panel with electronics, operating elements and built-in room temperature

sensor.

•Mounting base with power electronics.

The rear of the mounting base contains the screw terminals.

Slide the front panel in the mounting base and snap on.

Engineering notes

See the "Reference documentation", page 15 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

Mount the room thermostat on a conduit box. 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 / Dismounting

•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.

•RDF301… : In case of limited space in the conduit box use the mounting

bracket ARG70.3 to increase the headroom by 10mm

•Before removing the front cover, disconnect the power supply.

Wiring See the mounting instructions M3171... and M3076.1 enclosed with the

thermostat.

•Comply with local regulations to wire, protection and earth the thermostat.

•The device has no internal fuse for supply lines to fan and actuators. To avoid

risk of fire and injury due to short-circuits, the AC 230 V mains supply line must

have a circuit breaker with a rated current of no more than 10 A.

•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 wiring cross section used for power supply (L, N), fan (Q1, Q2, Q3,N) and

230 V outputs (Yx -N) must be adapted to the preceding overload protection

elements (10A) under all circumstances. Comply under all circumstances with

local regulations

•Cables of SELV inputs X1-M/X2-M: Use cables with 230 V insulation, as the

conduit box carries AC 230 V mains voltage.

•Inputs X1-M or X2-M of different units (e.g. summer/winter switch) may be

connected in parallel with an external switch. Consider overall maximum

contact sensing current for switch rating.

•KNX communication cables (input CE+ / CE-): Use cables with 230 V

insulation, as the conduit box carries AC 230 V mains voltage.

•No metal conduits.

•No cables provided with a metal sheath.

•Disconnect from supply before opening the cover.

•When a KNX bus power supply is connected on the line with communicating

thermostats and Synco controller, the internal KNX power supply of the Synco

controllers must be switched off.
