NOTE: In any wall-mount application, the air
within the wall cavity can cause erroneous
readings. The mixing of room air and air from
within the wall cavity can lead to condensation,
erroneous readings and sensor failure.
To prevent these conditions, Greenheck
recommends sealing the conduit leading to
the junction box, filling the junction box with
fiberglass insulation or sealing the wall cavity.
