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 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.
Assigning the Thermistor for Temperature Detection
Each indoor unit includes a return air thermistor assigned to sense the temperature. If a wired controller is installed, there is a choice
of sensing temperature with either the indoor unit return air thermistor or the thermistor in the wired controller. It is also an option to set
both thermistors to sense temperature so that indoor unit bases its operation on the first thermistor to reach the designated temperature
differential.
