Question Image

The Hitachi PC-ARFH2E is the wired Unit Main Controller for the Yutaki M 11 to 16 kW, new Yutaki S, S-Combi, and Hydrosplit 4 to 7 HP ranges. It provides the user interface for setpoint adjustment, scheduling, weather compensation, DHW management, and fault diagnostics. The controller is a required accessory for any Hitachi Yutaki heat pump install — the outdoor unit does not ship with a user interface.

Use this PC-ARFH2E specifically with: Yutaki M 11/12/13/16 kW outdoor units, plus the new Yutaki S, Yutaki S-Combi, and Hitachi Hydrosplit 4 to 7 HP ranges.

Accessory Status
PC-ARFH2E compatibility band. This controller is specifically matched to Yutaki M 11 to 16 kW, new Yutaki S, S-Combi, and Hydrosplit 4 to 7 HP. For other Hitachi Yutaki ranges, check the alternative PC-ARFH variant — using the wrong controller will result in commissioning errors.
Why a Hitachi-original controller matters. Generic or third-party controllers don't speak the Hitachi protocol — only the original PC-ARFH controllers expose the full FTC functionality, weather compensation curves, and fault diagnostics needed for an MCS-compliant install.

About the PC-ARFH2E Controller

Full FTC platform user interface

Setpoint adjustment, time schedules, weather compensation, DHW priority and Legionella cycle control, all in one wired interface.

Wired connection to outdoor unit

Direct wired connection — no batteries, no wireless dropouts. Mounted in the user-accessible location (typically the airing cupboard or hallway).

Fault diagnostics on display

Error codes are displayed directly on the controller, simplifying maintenance and reducing engineer call-out time.

Pairs with WiFi Gateway

Add the ATW-IOW-01 WiFi IoT Gateway separately to extend the controller into the Hitachi CSNET Home app for remote access.

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.
