DripTime Drip Time Amount of time after defrost for the coil to drip. (0 to 30) min
MaxWait Max Wait
Refrigeration starts if in wait period and the end-
wait input is active. If no supervisory controller is
available (offline), the application ignores the
end wait-input and will not use it for the start
refrigeration logic.
