5.1 Mounting and installation
Do not mount on a wall in niches or book-
shelves, behind curtains, above or near heat
sources, or exposed to direct solar radiation.
Mount about 1.5 m (5 feet) above the floor.
The room thermostat must be mounted in a clean, dry indoor place and must not be
exposed to drip or splash water.
See Mounting Instructions (M3181.. or M3183..) enclosed with the thermostat.
Comply with local regulations to wire, protection and earth the thermostat.
Warning!
No internal line protection for supply lines to external consumers (Q1, Q2, Q3,
Yx or Yxx)
Risk of fire and injury due to short-circuits!
Adapt the line diameters as per local regulations to the rated value of the installed
overcurrent protection device.
The AC 230 V mains or AC 24 V supply line must have a circuit breaker with a rated
current of no more than 10 A. For AC 24 V US installations, use Class 2 rated
power supplies.
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 on RDG100.., RDG110 and on
RDG160T if AC 230 V is connected to the "L" terminal.
Use only 3-speed fan rated with AC 24 V on RDG160TU.
Isolate the cables of inputs X1-M/X2-M and D1-GND if the conduit box carries
AC 230 V mains voltage.
On the RDG100.. and RDG110, inputs X1-M and X2-M carry mains potential.
If the sensor’s cables are extended, they must be suited for mains voltage.
Inputs X1-M, X2-M or D1-GND 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.
Selectable relay function (RDG160T..). Consider overall maximum current though
the relays.
Disconnect power supply before removing the thermostat from the mounting plate!
