Programmable Zone Sensor Installation

Mounting Location

Mount the sensor on the wall in an area with good air circulation at an average temperature. Choose a location that is easily accessible, and on a wall where the subbase can be mounted about 5 feet (1.5 meters) above the floor.

Avoid mounting space temperature sensor in areas subject to the following conditions:

•Drafts or “dead” spots behind doors or in corners

•Hot or cold air from ducts

•Radiant heat from the sun or appliances

•Concealed pipes and chimneys

•Unheated or non-cooled surfaces behind the sensor, such as outside walls

•Airflows from adjacent zones or other units

Installation Procedure

1.Remove the zone sensor module from the subbase. Carefully hold the zone sensor module with one hand and firmly grasp the subbase with the other. See Figure I-PR-20.To remove the zone sensor module from the subbase, gently pull away and upward.

Note: The zone sensor module is an electronic sensitive device. Do not touch printed circuit board, electronic compo- nents, or connector pins. Handle plastic housing only to prevent damage to electronic components.

2.After disassembly, protect the internal surfaces from contact with objects or substances that could cause damage.

3.Remove the terminal block from subbase and set aside for wiring. Discard the tape.

4.Mount the zone sensor module using the mounting hardware included in the shipping package. The mounting hardware is contained in single plastic bag and includes:

•Plastic wall anchors (3 x)

•Mounting screws (3 x)

The zone sensor module can mount directly to a wall or to a junction box mounted to a wall.To mount to a junction box, you must have the mounting plate and adapter kit, BAYMTPL003. Installation instructions are enclosed with the mounting plate.

5.To mount the zone sensor module directly to a wall:

a. Hold the subbase in position and mark the three mounting hole locations on the wall.

b. Drill three 3/16” (4.8 mm) holes. Gently tap the plastic wall anchors into the holes until the anchor tops are flush with the wall.

6.Pull the zone sensor module wires through the subbase as shown in Figure I-PR-21.

7.Loosely secure subbase to the wall with the mounting screws. Do not tighten the subbase screws yet.

8.Level the subbase by sight, then firmly tighten the three subbase mounting screws.

Note: Do not overtighten the subbase screws. Overtightening may cause the

screws to crack the subbase.

9.Before wiring the subbase, identify the wires from the unit’s low voltage terminal strip. Each screw terminal is labeled.

10.Remove TB from subbase and discard the tape.

11.Strip the wires 1/4” and connect the wires from the unit’s low voltage terminal strip to the zone sensor module subbase. Reference connection details on the unit wiring diagrams, located on the unit.

12.Firmly tighten each screw terminal.

13.Fit the wires as close to the subbase as possible.
