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.
 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
