• When using the HBA function on the E5AK-AA2 controller, connect
CT input (CT) to terminal Nos.15 to 17. When monitoring the valve
opening on the E5AK-PRR2 controller, connect the potentiometer

• For details on the potentiometer, see the Instruction Manual for the
valve connected to the controller. The variable resistance range is 100
Ω to 2.5 kΩ.
• Connect an input (RSP) to be used as the remote SP to terminal
Nos.21 and 22.
