Ref 1. When the Set Point value is wrong for the regulation, then “Err” is displayed and the Set
Point value is initialized to ‘0’.
Ref 2. The Regulation has to be observed for the sequential 3 step control and the 1
st

rd
step outputs
are computed as follows.
1
st
Step Output = Final (Set Point 4) – Optional preliminary(Set Point 2)
