Installation instructions Position The installation site of the remote probe should be chosen such that a representative measurement of air humidity can be guaranteed. Avoid areas in the vicinity of radiators, doors and exterior walls, as well as direct sunlight. Do not position the sensor where ingress of water could occur. IP65 protection is - only ensured with PTFE sintered filter ZE05 with O-Ring - only ensured when the probe is plugged, see „Probe pluggable“ on page 4. We recommend that you lay the connection lines in a loop so that any water that may be present can run off. Operating temperature...
