The ‘PROGRAM’ key is used to program the system

the desired language.
Pressing the ‘ENTER’ key repeatedly allows scrolling

This safety is bypassed for the first 5 seconds of opera-
tion after which if the cutout point is exceeded for 3
seconds, the system will shutdown.
Normally, the cutout should be set at 26.5 bar. The
microprocessor will, however, accept values between
13.8 and 27.52 bar.
