3.1 Mounting and installation
● Mount the room thermostat on a recessed square conduit box with 60 mm
fixing centers.
● 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.
● 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.
● In case of limited space in the conduit box, use mounting bracket ARG70.3 to
increase the headroom by 10 mm.
● See Mounting Instructions A6V12060783 enclosed with the thermostat.
● Comply with local regulations to wire, protect 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.
● Adapt the wiring cross section for power supply (L, N), and 230 V outputs
(Yx-N) to the preceding overload protection elements (max 10 A) under all
circumstances. Comply with local regulations under all circumstances.
● Cables of SELV inputs S1 (X2)-M / B1 (X1)-M: use cables with min 230 V
insulation, as the conduit box carries AC 230 V mains voltage.
● Inputs S1 (X2)-M / B1 (X1)-M: several switches (e.g. summer/winter switch)
may be connected in parallel. Consider overall maximum contact sensing
current for switch rating.
● Selectable relay function: Follow the instructions in Basic documentation
A6V12114068 to connect external equipment to the relay outputs.
● Isolate the cables of Modbus communication input A+, B- and REF for
230 V.
● Disconnect thermostat from power supply before removing from the
mounting plate.
● The device does not support hot-plug.
