6 Parameters
s-hc
• This parameter selects standard control or heating/cooling control.
• If heating/cooling control is selected for the E5CC, E5CC-B, E5CC-U, E5DC, or E5DC-B
when there is only one control output, the auxiliary output 2 terminal is assigned as the
Function
control output for cooling. (If the Digital Controller has only one auxiliary output, an output
is not automatically allocated for the control output for cooling.)
• If heating/cooling control is selected for the E5EC, E5EC-B, or E5AC when there is only
one control output, the auxiliary output 4 terminal is assigned 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.
