s-hc
• This parameter selects standard control or heating/cooling control.
• When heating/cooling control is used on the E5CC, E5CC-U, or E5DC and there is only
one control output, auxiliary output 2 is allocated as the control output for cooling. (If the
Function
Digital Controller has only one auxiliary output, an output is not automatically allocated for
the control output for cooling.)
• When heating/cooling control is used on the E5EC or E5AC and there is only one control
output, auxiliary output 4 is allocated as the control output for cooling. (If the Digital
Controller has only two auxiliary outputs, auxiliary output 2 is allocated as the control
output for cooling.)
• When heating/cooling control is selected for the E5GC, auxiliary output 1 is assigned as
the control output for cooling.
Note: If standard control is selected, set the Control Output 1 Assignment to o (control output
(heating)) for either direct (cooling) or reverse (heating) operation.

st
• 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
Function
simultaneously with or before starting E5@C operation.
• Auto-tuning can be started during self-tuning.
