switching on and off during a defrost in two-zone operation. In single-zone mode only defrost sensor R1.1
controls the fan relay.
R1.1: Defrost sensor (Terminal Z31/Z32)
Expansion valve 1: Expansion valve 1 (Terminal 23/24)
Fan 1: Fan control relay (Terminal 73/74)
When thermal fan start delay is set, the fan does not start for a time after defrosting is terminated so as to
prevent warm air being forced into the display case.
The fan relay is the inverted type:
when the controller turns on the fan, then the relay contact (73/73) is opened;
when the controller turns off the fan then the relay contact (73/73) is closed.

The enhanced functions for the fan control must be activated via the DIP switch S3 on the circuit board of the
case controller.
Apart from the terminal assignment of the analogue inputs for temperature sensors, the terminal assignment is
identical to the terminal assignment of the UA 131 E, see chapter
