Installation Manual
This reference should remain on site with the installed KE2 Temp + Defrost controller.
A

Select Mounting Location

The KE2 Temp is designed for a wide range of applications; therefore
there are many potential installation locations. Breaking down the in-
stallation location by application provides the most helpful reference.
Application Locations
Under counter Evaporator cabinet
Outside controlled space
Walk-in Evaporator cabinet
Adjacent to entrance
Side-by-side Above door
Remote Monitoring, Control, Alarm Notifications
The KE2 Temp includes RS-485 Modbus communications, and can now
be accessed remotely using the KE2 Local Area Dashboard and Alarms
(KE2 LDA). See page 4 for additional details.
Service Call Saver -
Post Defrost Indicator
To eliminate unnecessary service calls, the KE2 Temp + Defrost alerts
the user when it is coming out of a defrost cycle using the onboard
display. The display alternates between dEF and the actual temperature
measured by the air sensor. This continues until the temperature has
reached setpoint, or for the amount of time set by dFt (Defrost Time)
whichever is shorter.
