Quick set up

Step 1:

Unpack the Procon IO-Interface and secure it in place.

Step 2:

Set the dip switches on the Procon IO-Interface depending of the requirements.

Step 3:

Connect inputs and outputs depending of the requirements.

Step 4:

Connect the Procon IO-Interface to the CN105 terminal on the indoor unit.

Step 5:

Check that the power LED is flashing for some time (start up time) and then becomes solid. The comms
LED will then start flashing.

Step 6:

Check the output LED matches the indoor unit settings (On/Off, Heat/Cool…).

Important note:

When using energy save features, it is important to use a remote sensor (PAC-SE41TS) or the remote controller
sensor to accurately read the room temperature.

• Use the specified cables for wiring. Make the connections securely so that any outside forces acting on the cables are
not applied to the terminals

- Inadequate connection and fastening may generate heat and cause a fire

• Never repair the unit. If the controller must be repaired, consult the dealer

- If the unit is repaired improperly, electric shock, or fire may result

• When handling this product, always wear protective equipment. EG: Gloves, full arm protection and safety glasses

- Improper handling may result in injury

• Have all electric work done by a licensed electrician according to "Electric Facility Engineering Standard", "Interior Wire
Regulations" and the instructions given in this manual and always use a special circuit

- If the power source capacity is inadequate or electric work is performed improperly, electric shock and fire may result

• Keep the electric parts away from any water - washing water etc…

- Contact may result in electric shock, fire or smoke

• Do not reconstruct or change the settings of the protection devices

- If the protection device is shorted or operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or
explosion may result

• To dispose of this product, consult your dealer

Caution:
