Access code
Used sensor type for Sc3, Sc4 and "Saux1"
0=PT1000, 1=PTC1000
2-7=variations with temperature sensor
on P0 and Pc. See earlier in the manual.
Set supply voltage frequency
Manual control of outputs:
0: No override
1-10: 1 will cut in relay 1, 2 relay 2, etc.
11-18: Gives voltage signal on the analog
output. (11 gives 1.25 V, and so on in steps
of 1.25 V
