List of parameters
A1 Sets the unit of measure for dew point in °C or °F.
A2/A3 Total hours of dryer operation= A3x1000+A2(display only).
A4/A5 Like A2/A3 but for hours of refrigeration compressor opera-
tion.
A6 Sets Hd Warning intervention temperature (see par. 5.4 in
List of alarm/warnings).
A7 Inhibits remote OFF command.

b7 Not available
b8 Compressor discharge (delivery) temperature
b9 Not available
C5 250
Dryer model: Mon = models
Mul = models
Note: if the C5 is set to = Mul in a monocooler dryer then
the warning ASE will occur. ASE is a warning for the mul-
ticooler models.
C7 Not available
