Introduction
μChiller uses the user terminal to display the alarms, the main variables and to set the unit set points
(User level) and manual functions (Service level). The terminal has a 7- segment LED display with two
rows: the top row is 3-digit plus sign and decimal point; the bottom row is 4-digit plus sign (this can also
display the hour format -hh:mm and date - MM:DD). There is a buzzer, 14 operating icons and 4 buttons
for scrolling and setting the parameters. The terminal has NFC (Near Field Communication) and
Bluetooth (depending on the model) connectivity for interaction with mobile devices (on which the Carel
“Applica” app has been installed, available on Google Play for the Android operating system).
Note: access levels: U=User; S=Service; M=Manufacturer. See the parameter table.
The unit of measure on the display can be changed via parameter UoM, accessed at a Service level,
including in the direct access functions menu.
