Adaptive defrost
Adaptive defrost automatically adjusts the frequency and length of each defrost interval to achieve
an optimised defrost duration for each defrost interval. You set up the expected defrost duration,
the first defrost interval, and a defrost termination temperature. Initially, the system uses the
first defrost interval until it automatically adapts to the existing conditions. The adaptive defrost
feature adjusts the length of the defrost interval so that the expected defrost duration coincides
with the time that the evaporator reaches the termination temperature. The defrost sensor
determines when the defrost duration is complete. See
Adaptive defrost setup parameters
information.
Compressor and evaporator fan start delays
To control the operation of the compressor and evaporator fan, set up the following time delay
features on the controller:
• Compressor anti-short cycle delay (ASD)
• Evaporator fan drip-time delay
• Evaporator fan time delay
When the controller is in a delay period, the UI message field displays the delay type and the
number of minutes that remain in the delay period.
