Sensor Mounting; Installation - Trane SENS-IN-1D18-HD60D29-4 Installer's Manual

Sensor Mounting

1. Mounting location.
- Choose a location on an interior wall near the return
air grille, approximately five feet above floor level,
where air circulates freely and is of average
temperature for the zone.
- Avoid areas such as:
behind doors;
on outside walls, or any walls with unconditioned
areas behind the sensor;
in direct sunlight, or any source of radiant heat that
could affect the temperature measurements;
in line with the discharge air from the unit being
controlled.
2. Mounting the sub base.
The mounting hardware is contained in a plastic bag that
includes;
3 - plastic wall anchors
3 – mounting screws
1 – terminal strip (TB), set aside for later use.
- Remove the sensor from its sub base.
Hold the Sensor with one hand and firmly grasp the
sub base with the other hand. Gently pull the bottom,
away and upward. Refer to Figure 1.
After disassembling the sensor, protect the internal
surface from contacting objects or substances that
could cause damage.
- To determine the appropriate number of wires
required, refer to Figure 3.
- Route the wires from the wall through the wire access
hole in the sub base. Refer to Figure 2.
- Mount the sub base directly on the wall or on a 2X4
handy box (Handy Box must be installed
Horizontally).
To mount the sub base directly on the wall, hold it in
place and mark the three holes. Drill three 3/16 inch
(4.8 mm) holes. Gently tap the plastic anchors into
the holes until they are flush with the wall. Level the
sub base and firmly tighten the mounting screws.
OVER TIGHTENING THE SCREWS could crack the
sub base.
To mount the sub base on a 2X4 handy box mounted
horizontally, Level the sub base and firmly tighten the
mounting screws. OVER TIGHTENING THE
SCREWS could crack the sub base.
If the handy box is installed vertically, a mounting
plate and adapter kit (#BAYMTPL003B) is required.
Follow the instructions that are enclosed with the
mounting kit.
- Seal the hole in the wall behind the sub base.

Conductors and Terminal Identification
Operating Power (2 Wires)
24 VAC power supplied from the Unit Control provides the
operating power for the ZSM. The power supply should be
connected to the terminals 11 & 14 on the ZSM.
Remote Zone Temperature Sensor (2 Wires Optional)
The ZSM supports the use of a remote zone temperature
sensor. The remote sensor should be a thermistor type sen-
sor (Baysens017). When connecting the remote sensor, use
terminals S1 and S2 on the ZSM. Connect the Shield wire
(drain wire) from the shielded cable to terminal 11 on the
ZSM.
Note: When using a remote sensor, Option # 11 in
the OPTION MENU must be set to "1".
Communication (1 Wire)
Data communication between the UCM and the ZSM is ac-
complished over a serial link connected at terminal 12 on
the ZSM.
