Defrost Mode

Defrost cycles are usually initiated automatically based on time and demand.

The operator can also initiate a manual defrost if necessary. Manual defrost is only available if the unit is running and the evaporator coil temperature is less than or equal to 45F (7C).

• If the defrost parameters are met — HMI will display “PROGRAMMING DEFROST“ followed by UNIT IS DEFROSTING”.

• In Defrost Mode, the trailer temperature box will be replaced by defrost information and trailer temp box and dashboard will change its color to “purple”.

• Additionally, the return air temperature (trailer temp) will be replaced by the coil icon and a intermediate spinner on top with a display progress bar for the remaining defrost time across the bottom.
