U-Line CO2175/CO2275DWR Manuale Utente

Three or four thermistors are employed. All are of the type 2. 
These measure the refrigerator, freezer, ice maker, or evaporator 
drain pan.

A reed switch is mounted to the underside of the cabinet and a 
magnet is mounted to the door. When the door is closed the 
magnet trips the switch which turns the light and display off.

For the CO2175DWR model there is a second reed switch 
mounted on the inside rear left corner of the top drawer.

Both drawers are monitored individually; however, when either 
drawer is opened both cabinets light and the displays energize.

These units defrost on time and temperature. The Defrost Cycle 
runs for a minimum of 18 minutes (adjustable), and stops at a 
maximum of 45 minutes or when T4 reaches 42°F (non-
adjustable), whichever comes first.
