z Control output 1
The following diagrams show the applicable outputs and their internal equivalent circuits.
E5DC
E5GC
z Auxiliary Outputs 1 to 4
• 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 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.
