Auxiliary Outputs 1 to 4
• If heating/cooling control is selected for the E5CC, E5CC-U, E5CC-B, E5DC or E5DC-B when
there is only one control output, the auxiliary output 2 terminal is assigned 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.)
• 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.
