OPERATiON AND FUNCTiONS (Continued)
Defrost
• Defrost type: it can programmed for hot gas or electric heater
defrost. An off cycle defrost type can be configured by selecting
the electric defrost option and not connecting any device to the
defrost relay.
• Number of defrosts per day: between 1 and 8. There is also an
option for 1 defrost every 48 hours.
• Defrost cycle: a choice among defrost start time (real time clock),
accumulated compressor run time or temperature initiation defrost
• Fan delay: amount of time that the fan will remain off after defrost
is terminated (0 to 15 minutes).
• Pump down: amount of time the compressor remains on after
defrost initiates (0 to 59 minutes).
• Drip time: amount of time the compressor remains off after defrost
is terminated (0 to 59 minutes).
• Defrost duration time: amount of time for the defrost duration.
It also functions as a back-up for temperature termination.
• Defrost termination temperature: temperature that will cause the
defrost to terminate (if reached before defrost duration time).
• Fan start temperature: temperature that will cause the fan to re-start
after defrost.
Setpoint
• Setpoint temperature (cut-out): a setpoint temperature can be
programmed to control the compressor operation. The range is
-40° to 60°F.
• Cut-in differential: differential between the cut-out (setpoint) and
the cut-in temperature. The range is 1° to 25°F.
• High and low temperature alarm setpoint: high and low alarms for
the temperature can be set. The ranges are -40° to 60°F for each of
the alarms (high and low).
