Overview and General Installation
This document gives wiring details, schematics of sample applications
(including bills of material with KMC Controls products), and other
related information.
Wire the FlexStat to the desired equipment (see below for general pur-
pose wiring and switch conguration) and select the relevant program
from the (Advanced) Application submenu of the Advanced Menu and
other appropriate menus.
For general mounting and connection details, including network wir-

Overview
Mounting Considerations
FlexStats must NOT be:
• Mounted on an exterior wall.
• Mounted on or near a large thermal mass (e.g., concrete block wall).
• Blocked from normal air circulation by obstructions.
• Exposed to heat sources (e.g., lights, computers, copiers, or coee
makers) or to sunlight (at any time of the day).
• Exposed to drafts from windows, diusers, or returns.
• Exposed to air ow through the conduit (from leaks in plenum
ducts)—put plumber’s puy or similar material inside the conduit to
block air ow.
• Mounted on the wrong backplate (see below).
