1: actual value at I7
2: setpoint plus hysteresis value
3: setpoint
4: setpoint minus hysteresis
The n/o contact switches off when the actual value at I7
exceeds the setpoint plus hysteresis. If the actual value at I7
equals or falls below the setpoint, the n/o contact switches on.

The values F2 +0 and OS +0 were not defined. No
values are used with a gain factor, and no offset is used.
A gain factor of 10 is used with the analog value at I8. The
hysteresis is adjusted accordingly.
