Mounting and installation
● Mount the room thermostat on the 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.
● Mount the room thermostat in a clean, dry indoor place without direct airflow from a heat-
ing / cooling device, and not exposed to dripping or splash water.
● Before removing the front cover, disconnect the power supply.
● See Mounting Instructions A6V12064527 enclosed with the thermostat.
● Wire, protect and earth in compliance with local regulations.
● Adapt the line diameters to the rated value of the installed overcurrent protection device
as per local regulations.
● Use only valve actuators rated for AC 230 V.
● The AC 230 V mains supply line must have an external circuit breaker with a rated
current of no more than 10 A.
● Isolate the cables of SELV inputs X1-M/X2-M, if 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.
● No metal conduits
● No cables provided with metal sheathing.
● Disconnect the thermostat from power supply before removing from the mounting
