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.
