quIck Install
TDDA
Drill a hole in the duct.1.
Insert the temperature probe, until the junction box is flat against the outer 2.
surface of the duc t.
Use screws to secure the junction box to the duct.3.
Wire as shown (see Wiring sec tion).4.
TOA
Locate sensor in an outside area, out of direct sunlight (e.g. under an eave, north 1.
side of building).
Mount the housing. 2.
Wire as shown (see Wiring sec tion).3.
TWxA and TW
Mount the housing vertically on an interior wall in the area to be monitored, in 1.
a location where air circulates freely. Locate unit away from air outlets, corners,
exterior walls, windows, and doors.
Wire as shown (see Wiring sec tion).2.
