1. Startup/Cool Down

MH and PH energize. There is a slight delay before cabinet temperature or

high‑temperature alarm (Hi) appears on DM and Comp, ConFM, and EvapFM energize.

2.Cool Down Achieved

CM monitors cooling of the cabinet via CTh. CTh cools to 3°F (1.7°C) below setpoint. EvapFM, MH, and PH continue. Comp and ConFM de-energize.

3.Cool Down Restart

CTh warms to 3°F (1.7°C) above setpoint. EvapFM, MH, and PH continue. Comp and ConFM energize.

4.Defrost

"dEF" is displayed during defrost. There is a 5-minute minimum defrost time and a 1-hour maximum defrost time.

a)Temperature/Time Initiation: DTh cools to 32°F (0°C), then a 4-hour cumulative Comp run timer starts. Once 4-hour cumulative Comp run timer terminates and DTh is at or below 32°F (0°C), defrost begins. DH energizes, MH and PH continue, Comp, ConFM, and EvapFM de‑energize.

b)Manual Initiation: Manual defrost may be initiated by pressing and holding the lower button until "dEF" appears on DM. MH and PH continue. DH energizes, Comp, ConFM, and EvapFM de-energize.

c)Termination

(1)After Temperature/Time Initiation: DTh warms to 59°F (15°C). 3-minute Comp delay timer starts, 8-minute EvapFM delay timer starts, and 13-minute temperature display delay timer starts. MH and PH continue, DH de-energizes.

3-minute Comp delay timer terminates. Comp and ConFM energize. 5 minutes later, 8-minute EvapFM delay timer terminates and EvapFM energizes. 5 minutes after EvapFM energizes, 13-minute temperature display delay timer terminates and cabinet temperature returns to DM.

(2)After Manual Initiation: DTh warms to 59°F (15°C). MH and PH continue, DH

de‑energizes. 3-minute Comp/EvapFM delay timer starts, 13-minute temperature display delay timer starts.

3-minute Comp/EvapFM delay timer terminates. Comp, ConFM, and EvapFM energize. 10 minutes later, 13-minute temperature display delay timer terminates and cabinet temperature returns to DM.

Note: There is a 4-hour minimum defrost interval.
