*1.
The options that can be selected depend on the type of control output.
*2.
The control output cannot be used as a transfer output.
*3.
A model with four auxiliary outputs must be selected.
Note:
Draw-out-type models of the E5EC and E5AC are available. Ask your OMRON representative for details.
Heating and Cooling Control
Using Heating and Cooling Control
A
Control Output Assignment
If there is no control output 2, an auxiliary output is used as the cooling control output.
If there is a control output 2, the two control outputs are used for heating and cooling.
(It does not matter which output is used for heating and which output is used for cooling.)
B
Control
If PID control is used, you can set PID control separately for heating and cooling.
This allows you to handle control systems with different heating and cooling response characteristics.
