Installing Wall Mounted Controls
Fan Mode Switch Installation
Figure 24. Fan Mode Switch
Wall mounted controls, which include the fan mode switch and the zone sensor module, ship loose inside the unit accessory bag.
Position the controller on an inside wall 3 to 5 feet above the floor and 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.
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 control, such as outside walls or unoccupied spaces.
·Concealed pipes, air ducts, or chimneys in partition spaces behind the controller.
The fan mode switch ships loose inside the unit accessory bag. Follow the steps below to install the fan mode switch.
