Mounting instructions
The Room Unit receives its power from the connected controller via the 2-wire interface (low voltage,
SELV). The Room Unit must be connected to the main unit with an unscreened two-core twisted pair cable.
Following some advices for the correct mounting and operation:
-
The unit should not be mounted in recesses, shelving, behind curtains or doors or above or near direct
heat sources.
-
Avoid direct sun and draught.
-
The conduit must be sealed on the device side, as currents of air in the conduit can affect the sensor
reading.
-
The admissible ambient conditions must be observed.
