Service Information
Refer to the operating instructions on page 4 for operating instructions.
When mains electrical power is first applied to the controller it will carry out a self test function, for approximately 3
seconds, to ensure that there are good connections between the component parts. During this period the display will
show.
The information displayed in the centre of the screen refers to which of the profiles the controller is set for.
The software version relates to the software release. The number relates to the major operating changes or model
variants. The letter relates to the minor operating changes that may have been made from the original, such as parameter
settings.
On completion of the self test the controller will revert to the last chill program that was run (Pre-chill, Soft Chill, Hard Chill,
Hard Chill Max, Shock Freeze, Professional 1, Professional 2, or Professional 3). The availability of these is dependent on
how the controller has been configured. The example below shows the controller in Hard Chill.
Press and hold the dial for 5 seconds.
Firstly the display will display the information page, below left, continue pressing until the ‘SERVICE’ screen is displayed,
below right. For changes to language see page 5.
