Typical Control
Examples
2. Press the L key for less than 1 second to move from "Input initial setting
level" to "Control initial setting level".
3. Press the M repeatedly to select "mode: Control mode". Press the U key
to select "1: Heating/cooling control".
4. Hold down the L key for at least 1 second to return to "RUN level". "PV/
SP/MV" will appear. Press the U key to set the value to "250.0".
5. Press the L key less than 1 second to move from "RUN level" to
"Adjustment level".
6. Press the M repeatedly to select "c-sc: Cooling coefficient". Press the D
key to set the SP to "0.50".
■ Adjustment
To adjust the PID constants, run AT.
For more information, see"4.10 Determining the PID constants (AT,
manual settings)" (P.4-20).
