Wired controller Placement
Wall-mounted indoor units can be used with various wired controllers (optional; sold
separately). Wired controllers include a sensor to detect room temperature. To main-
tain 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 average 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
