4.4.2 POST DEFROST DRIPDOWN
Post Defrost Dripdown can be used only with active defrost e.g. Heater or Hot Gas defrost. After defrost has been terminated
by either time or temperature (depending on configuration), the JEA will turn the compressor, fan and defrost relay OFF until
the evaporator temperature drops to the set temperature (if an evaporator probe is fitted) or the maximum dripdown duration
has elapsed to prevent freeze up by allowing excess moisture to drip off the evaporator coil. Once dripdown is terminated the
JEA will resume normal operation.
Operation During Post Defrost Dripdown
Compressor: OFF
Evaporator fan: OFF
Defrost Relay (if fitted): OFF
4.5 WINTER MODE
Winter mode is designed for when coolers are in extremely cold temperatures (For example: outdoor coolers in cold countries
such as Russia) and require a heater to be fitted. The compressor will be turned OFF and the heater will be turned ON. This is
to warm up the inside of the cooler to ensure products in the cooler do not get too cold and freeze. Winter mode is entered
automatically based on configurable parameters.
Standard operation During Winter Mode
Compressor: OFF
Evaporator fan: ON
Cabinet Heater (if fitted): ON
