Building Technologies 2017-03-14
On applications with EMC problems, use shielded cables. For secondary power lines
and signal lines, use twisted-pair cables.
Mounting notes
Inner wall of the room to be ventilated, not in niches, not behind curtains, not above or
near heat sources, and not exposed to direct light from spot lights.
Do not expose the sensor to direct solar radiation.
Seal the end of the conduit at the sensor to prevent false measurements due to drafts
through the conduit.
Mounting instructions are enclosed in the package.
