When checking P.I.D. values or setting SV in manual mode, this can be done in P.I.D. Group.
Press key to get Anti Reset Wind value by auto or manual and then press once more to be
indicated P.I.D mode which is selectable 3 types of P.I.D group (0~3). Example, “0” is no P.I.D
mode and after Auto tuning “1” using or and pressing , it is available to change P.I.D
value in zone “1” (“2” and “3” are same as “1”)
When integral time is 0, manual reset mode is indicated and then you could set reset value to
remove off set (range: -5 % ~ 105.0 % of proportional band). You could set 3 zones by selecting
zone mode ON.
In diagram, “n” is available to set 1 ~ 3 and proportional band of cooling side, integral time of
cooling side, hysteresis are indicated in Heating / Cooling type.
