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 initializes it. It then automatically enters the In-
troduction Mode. The Introduction Mode consists of as little as 4 setpoints
that must be configured for the KE2 Evap to begin controlling the system.
