Hitachi Yutaki Unit Main Controller PC-ARFH2E (for Yutaki M 11 to 16 kW, new Yutaki S, S-Combi, and Hydrosplit 4 to 7 HP)
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.
About the PC-ARFH2E Controller
Setpoint adjustment, time schedules, weather compensation, DHW priority and Legionella cycle control, all in one wired interface.
Direct wired connection — no batteries, no wireless dropouts. Mounted in the user-accessible location (typically the airing cupboard or hallway).
Error codes are displayed directly on the controller, simplifying maintenance and reducing engineer call-out time.
Add the ATW-IOW-01 WiFi IoT Gateway separately to extend the controller into the Hitachi CSNET Home app for remote access.

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.
