remote temperature sensor Installation (PQrsta0)
The remote temperature sensor can be installed most places where
the occupant wants to measure the combined space temperature.
Follow the steps below for proper installation.
If the communications cable between the Hydro Kit and the loca-
tion for the Remote Sensor have not been installed, refer to the
Roughing-In section "LG Remote Temperature Sensor" on
page 40.
• Be sure to always power off Hydro Kit before installation of accessories.
• Never operate Hydro Kit outside of the operational parameters as
outlined in this manual and the product specifications.
• Never touch wiring or install accessories with wet hands.
Procedure
1. Locate the end of the communications cable for the Remote
Temperature Sensor that protrudes from the wall in the condi-
tioned space.
2. If a handy box was not installed, mark the wall with two dots.
Locate the dots about 1 inch to the right of where the cable
protrudes from the wall.
• The two dots should be on a vertical axis about 2-3/8 inches
apart with one hole about 1" above the cable protrusion from
the wall and the other below.
• Insert one screw into the wall on each dot leaving about 1/8" of
screw shank showing.
3. Terminate the two communications cable leads at the screw
terminals on the back side of the Remote Sensor. Polarity does
not matter (cN_rooM) (Figure 51).
4. Prepare the wall surface behind the sensor to eliminate any
chance of the sensor picking up a false reading.
• False readings can come from direct air and/or moisture
transfer from the wall cavity to the conditioned space through
an opening behind the sensor housing.
5. Seal all gaps, cracks, and holes in the wall surface and seal
around the communications cable penetration.
• Use a local code approved caulk or dry-wall compound.
6. Place the sensor casing directly over both the top and bottom
screws (see (1) on Figure 52).
• Slide the sensor housing downward on top of the two (2)
screws so that screw head fits snugly into the screw anchor at
the back of the unit (see (2) on Figure 52).
7. If the sensor housing is loose after hanging, remove housing
from screws, adjust screws again, and then re-hang.
• Repeat as needed, until sensor fits snug against the wall
surface.
