• This parameter selects standard control or heating/cooling control.
• With the E5CZ and E5CZ-U, when heating/cooling control is selected,
alarm output 2 terminal (ALM2) is used as a control output (cooling), so
alarm 2 cannot be used.
• With the E5AZ and E5EZ, when heating/cooling control is selected, alarm
output 3 terminal (ALM3) is used as a control output (cooling), so alarm 3
cannot be used.

• The ST (self-tuning) function executes tuning from the start of program
execution to calculate PID constants matched to the control target. When
the ST function is in operation, be sure to turn ON the power supply of the
load connected to the control output simultaneously with or before starting
Controller operation.
• Auto-tuning can be started during self-tuning.
