Auxiliary Outputs 1 to 4
When heating/cooling control is used on the E5CC, E5CC-U, or E5DC, auxiliary output 2 is the control output
for cooling unless the Controller has only one auxiliary output, in which case an output is not automatically
allocated for the control output for cooling. When heating/cooling control is used on the E5EC/E5AC, auxiliary
output 4 is the control output for cooling unless the Controller has only two auxiliary outputs, in which case
auxiliary output 2 is the control output for cooling.
