The Hitachi ATW-YCC-01 Cascade Controller enables multiple Hitachi heat pump units to operate together as a single coordinated system — typical in larger commercial installs, multi-property social housing schemes, or high-output domestic systems where a single heat pump cannot meet peak demand.

This variant is specifically matched to: Yutaki M 2 and 3 HP outdoor units, and the entire S-80 indoor range.

Application Class
Why cascade. Cascading multiple smaller heat pumps instead of a single very large one gives better part-load efficiency, redundancy (one unit can fail without losing the building), and modular sizing for phased projects.
ATW-YCC-01 is matched to a specific Hitachi range. This controller is specifically for Yutaki M 2 and 3 HP, and all S-80. The other Cascade Controller variant covers different Hitachi ranges — confirm your unit family before ordering.

Cascade Controller Capabilities

Coordinated multi-unit control

One cascade controller manages up to multiple Hitachi heat pumps as a single virtual system, with automatic sequencing and load balancing.

Redundancy through modularity

If one unit faults, the remaining units continue running. The system degrades gracefully rather than failing entirely.

Part-load efficiency

At low loads only one unit operates — keeping COP high. As demand rises, additional units stage in. The total system runs efficiently across the full output range.

Commercial & multi-property fit

Designed for installs above typical single-domestic scale — apartment blocks, social housing schemes, light-commercial buildings, MMC factory builds.

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.
