How to connect an external circulator to the PANASONIC WH-SXC09H3E8 air conditioner?

Frequently Asked Questions - 11/22/2025

Response Notice-Facile

To connect an external circulator to your PANASONIC WH-SXC09H3E8 heat pump, you must proceed safely and rigorously. Before any electrical operation, disconnect the device to avoid any risk of electric shock.

Recommended circulator: The installation manual recommends using an external circulation pump of type Yonos 25/6 (manufacturer Wilo), powered by AC 230V/50Hz with a maximum consumption of 500W.

Electrical connection: The external circulator connects via the CN-CNT connector available on the electronic board (PCB) of the unit. This connector serves as the dedicated connection point for the power supply of the external pump. The circulator must be powered by 230V single-phase, 50Hz, and its consumption must not exceed 500W to ensure compatibility with the system.

Installation steps: Locate the PCB in the electrical compartment of the air conditioner. Identify the CN-CNT connector. Connect the power cables (phase, neutral, and ground) of the circulator to the corresponding terminals of the CN-CNT connector. Ensure that all connections are tight and secure the CN-CNT cable using the provided cable tie to avoid excessive strain on the connectors.

Important checks: Check the compatibility of your circulation pump with the technical specifications (AC 230V/50Hz, power < 500W). Adhere to the applicable national wiring standards. Reconnect the device and test the operation of the circulator after installation.

Safety: If you are not comfortable with electrical operations, contact a qualified professional to perform the connection. Use only components recommended by the manufacturer to ensure the reliability and safety of the system.
