Actions Of The Temperature Control Module - Mitsubishi Electric MELSEC iQ-R Series User Manual

Actions of the temperature control module

The temperature control module executes PID operations with direct actions and reverse actions.
Direct action
In a direct action, the manipulated value (MV) increases when the temperature process value (PV) is larger than the set value
(SV). A direct action is used for cooling control.
Manipulated
value (MV)
Reverse action
In a reverse action, the manipulated value (MV) increases when the temperature process value (PV) is smaller than the set
value (SV). A reverse action is used for heating control.
