Hitachi Yutaki M Remote Control Mirror Box ATW-YMM-01 (for 4 kW and 8 kW)
The Hitachi ATW-YMM-01 is the optional indoor remote control mirror box for Yutaki M 4 kW and 8 kW outdoor units. It mirrors the outdoor-unit control connections to an indoor location, reducing the cable run to the outdoor unit and simplifying commissioning, fault-finding, and future service access.
Specifically matched to: Yutaki M 4.3kW (RASM-2VRE) and 8kW (RASM-3VRE).
Mirror Box Benefits
Wires installed at the outdoor unit are mirrored to an indoor terminal block — service engineers can read sensors and apply changes from a comfortable indoor location.
The indoor mirror box becomes the wiring hub — runs to the FTC controller, sensors and ancillaries terminate indoors rather than outside.
This is the ATW-YMM-01 variant, designed for the 4 kW and 8 kW Yutaki M outdoor units. Wrong-variant orders cause commissioning errors.
Strongly recommended on roof-mounted or restricted-access installations, where reducing trips to the outdoor unit saves significant time over the system life.

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.
