The Temp + Valve 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 + Valve alerts the
user when it is coming out of a defrost cycle using the onboard dis-
play. 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.
