DESCRIPTION AND CONFIGURATION OF THE PARAMETERS
c compressor
1 Minimum ON time
2 Minimum OFF time
3 Time between 2 start-ups
4 ON delay between the 2 compressors
5 OFF delay between the 2 compressors
6 Compressor rotation
0= disabled
1= enabled
7 Delay comp. ON from supply fan start-up
8 Hour counter threshold for the compressor
0= disabled
9 Hour counter compressor 1
A Hour counter compressor 2
type
F Fans
1 Fan operating mode
0= always ON
1= proportional speed regulation. If used
in condensation the fan is kept at minimum
even below the value of F5
2= proportional speed regulation. If used in
condensation the fan is switched off below
the value of F5, with an hysteresis of 0.5 bar
for pressure or 1°C for temperature
2 Minimum Triac voltage threshold
3 Maximum Triac voltage threshold
4 Triac pulse width
5 % regulation band for minimum speed or
temperature/pressure for minimum speed in
condensation
6 % regulation band for maximum speed or
temperature/pressure for maximum speed in
condensation
7 Minimum output value
8 Maximum output value
9 Fan hour counter threshold 0= disabled
A Supply fan hour counter
B Filter hour counter threshold 0= disabled
C Filter hour counter
D Supply fan OFF delay
E Fan pick-up time in condensation
