The Hitachi ATW-IOW-01 WiFi IoT Gateway connects a Hitachi Yutaki heat pump to the Hitachi CSNET Home app, giving the homeowner full remote control and energy monitoring via smartphone or tablet. The gateway wires into the existing PC-ARFH controller and joins the home Wi-Fi network — once paired, the heat pump is accessible from anywhere with an internet connection.

Manufacturer
Recommended on every Hitachi heat pump install. Remote monitoring transforms the user experience and gives installers visibility into operating performance without site visits. Specify the ATW-IOW-01 at install for a future-proof, app-enabled system.
Requires home Wi-Fi. The gateway needs a stable 2.4 GHz Wi-Fi connection in the cylinder cabinet or wherever the FTC controller is located. Confirm Wi-Fi coverage at the install location before ordering.

WiFi Gateway Features

CSNET Home app access

Free iOS and Android app — set schedules, change setpoints, monitor energy use, receive fault alerts.

Multi-zone control

Where the Yutaki system is configured with multiple zones, each zone can be controlled independently from the app.

Fault notifications

Push notifications alert the homeowner (and optionally the installer) to faults — enabling early intervention.

Hitachi installer professional view

Installers can register multiple client systems under a professional CSNET Home account for fleet oversight.

Frequently Asked Questions
Is Hitachi Yutaki MCS-certified for the BUS grant?

Yes — Hitachi Yutaki M is MCS-listed when installed by a certified MCS installer, qualifying the homeowner for the £7,500 Boiler Upgrade Scheme grant (subject to property eligibility).

Do I need a Hitachi-trained installer?

For warranty registration Hitachi requires the install and commissioning to be carried out by a Hitachi-approved engineer. Quality Heating can put you in touch with Hitachi-trained installers across the UK.

Is the controller included with the Yutaki M outdoor unit?

No — the Hitachi Unit Main Controller (PC-ARFH1E or PC-ARFH2E depending on kW) is a separate purchase. See our matching controller listings.

Can the Yutaki M run with my existing radiators?

In most cases yes, but radiators sized for an 80°C gas boiler may need uprating because heat pumps run at lower flow temperatures (typically 45–55°C on R32). A heat loss survey identifies which rooms (if any) need radiator upgrades.

Does the Yutaki M work with the Hitachi WiFi Gateway?

Yes — pair with the ATW-IOW-01 WiFi IoT Gateway (sold separately) for remote control, monitoring and integration with the Hitachi CSNET Home app.
