Defrost Timer – DEF1/F

$41.40

Microprocessor based defrost timer with four selectable cycle times and separately adjustable fan delay of 3-60 seconds and defrost time range from 0.3 – 60 minutes. The defrost time can be overridden, starting the cooling time first when contact 5 & 6 a rebridged permanently. Contact 5 & 6 can also be used as a temperature override. Closing contact 5 & 6 during the defrost cycle will start the cooling cycle. Any adjustment on the front potentiometers after the supply is applied is not acknowledged. This prevents unwanted changes of the time range.
