Wired Controller Placement
Wired controllers include a sensor to detect room temperature. To maintain comfort
levels in the conditioned space, the wired controller must be installed in a location away
from direct sunlight, high humidity, and where it could be directly exposed to cold air.
Controller must be installed four (4) to five (5) feet above the floor where its LED display
can be read easily, in an area with good air circulation, and where it can detect an aver-
age room temperature.
Do not install the wired controller near or in:
• Drafts or dead spots behind doors and in corners
• Hot or cold air from ducts
• Radiant heat from the sun or appliances
• Concealed pipes and chimneys
• An area where temperatures are uncontrolled, such as an outside wall
