4. Cool Down Restart
EvapFM and Comp icons are on. CTh warms to 4°F above setpoint. Comp icon turns on and Comp energizes. 3-min. Comp run timer starts.
5. Defrost Initiation
EvapFM and Defrost icons are on.
a)Automatic Defrost Initiation: EvapFM and Defrost icons are on. EvapFM continues. 6-hr. DT terminates. 30‑min. DT starts. If Comp run time < 3 min., Comp icon and Comp continue until 3-min. Comp run timer terminates. Once 3-min. Comp run timer terminates, Comp icon turns off, Comp de-energizes, and defrost starts.
b)Manual Defrost Initiation: EvapFM and Defrost icons are on. To initiate a manual defrost, press and hold the "+" button until the defrost icon turns on. EvapFM continues. 30‑min. DT starts. If Comp run time < 3 min., Comp icon and Comp continue until 3-min. Comp run timer terminates. Once 3-min. Comp run timer terminates, Comp icon turns off, Comp de‑energizes, and 30-min. DT starts.
Note: If the display module panel is locked, press and hold the "-" button and the power button until "UnL" appears briefly on the display module.
6. Defrost Termination
Comp icon is on. EvapFM icon flashing. 30-min. DT terminates. 6-hr. DT starts. Comp icon turns on and Comp energizes. 3-min. Comp run timer starts. 2-min. EvapFM timer starts, EvapFM icon starts flashing, and EvapFM de-energizes. When 2-min. EvapFM timer terminates, EvapFM icon turns steady and EvapFM energizes.
7. Energy Saving Mode
ESM initiates during periods of inactivity. Once CTh cools to setpoint, 20-min. ESM timer starts. DS must remain engaged without activation (door open) for 20 min. after CTh has achieved setpoint for ESM to initiate. Once 20-min. ESM timer terminates, EvapFM operates on ESM cycle. See "EvapFM ESM Cycle" below.
Note: If DS is activated (door open) before 20-min. ESM timer terminates, ESM timer resets and 20-min. ESM timer re-starts once CTh cools to setpoint again.
EvapFM ESM Cycle:
•If Comp is de-energized when 20-min. ESM timer terminates, EvapFM de-energizes.
•If Comp is energized when 20-min. ESM timer terminates, EvapFM continues and cycles off with Comp.
•During ESM Comp off time, EvapFM operation is 1 min. on and 5 min. off. EvapFM operates on and off with Comp.
