Installing Wall Mounted Controls
Wall mounted zone sensors ship taped to the control box. Refer to Figure 3 for zone sensor dimensions.
Position the controller on an inside wall three to five feet above the floor and at least 18 inches from the nearest outside wall. Installing the controller at a lower height may give the advantage of monitoring the temperature closer to the zone, but it also exposes the controller to airflow obstructions. Ensure that air flows freely over the controller.
Before beginning installation, follow the wiring instructions below. Also, refer to the unit wiring schematic for specific wiring details and point connections.
Wiring Instructions
Avoid mounting the controller in an area subject to the following conditions:
•Dead spots, such as behind doors or in corners that do not allow free air circulation.
•Air drafts from stairwells, outside doors, or unsectioned hollow walls.
•Radiant heat from the sun, fireplaces, appliances, etc.
•Airflow from adjacent zones or other units.
•Unheated or uncooled spaces behind the controller, such as outside walls or unoccupied spaces.
•Concealed pipes, air ducts, or chimneys in partition spaces behind the controller.
Zone Sensor Installation
Follow the procedure below to install the zone sensor module (see Figure 3).
Figure 3. Wall-mounted zone sensor dimensions
1.Note the position of the setpoint adjustment knob and gently pry the adjustment knob from the cover using the blade of a small screwdriver.
2.Insert the screwdriver blade behind the cover at the top of the module and carefully pry the cover away from the base.
3.To install the zone sensor module without a junction box (directly to the wall):
a.Using the module base as a template, mark the rectangular cutout for the control wiring and module installation holes. Ensure the base is level.
b.Set the base aside and make the cutout. Then, drill two 3/16” diameter holes approximately
c.Pull the control wires through the cutout and attach the module to the wall using the screws provided.
4.To install the zone sensor module to a standard junction box:
a.Level and install a 2” x 4” junction box (installer supplied) vertically on the wall.
