The controller controls refrigeration temperature. The controller is factory installed in the control
panel mounted on the merchandiser’s
fascia.
Discharge air temperatures should be measured at the center of the honeycomb. Defrosts are time
initiated and temperature terminated for these models. The defrost setting is set in the factory.
The product application is factory set for Med. Temp. - NSF7 as shown below.
