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.
