To function properly, the controller requires a room temp sensor (T2Air - blue) and a coil
temp sensor (T3Coil - yellow) . KE2 Therm strongly recommends the third sensor is used as
2nd coil temp sensor (T4Aux - green).
Introduction Mode
Applying power to the controller for the first time causes it to enter Introduction
Mode. Introduction Mode consists of as little as 4 setpoints that must be con-
figured to begin controlling the system.
