Eco-compact controller for VRF systems
22nd January 2026
FRANCE: The PC-ARC-E is a new simplified wired controller from Hitachi designed for VRF systems.
Delivering essential functionality with a focus on ease of use and value, the new controller is targeted at budget-conscious VRF projects.
According to Hitachi, its gently curved surface, 9×9 cm compact footprint, and clear pictogram-based interface make everyday operation effortless. Allowing 0.5°C incremental adjustments, its core functions are accessible directly from the home screen.
A single PC-ARC-E controller is capable of operating up to 16 indoor units.
Installers can configure the controller using the airCloud Tap smartphone app, saving and copying settings between rooms with a simple tap. The app also provides access to more than 140 parameters, system data, fault codes and maintenance information, supporting faster and more accurate diagnostics.
The PC-ARC-E includes practical energy-saving features such as weekly scheduling and peak cut operation to limit consumption during high-demand periods. Comfort features include gentle cool, which moderates discharge air temperature, and auto boost.
For residential use, a new sleep mode gradually adjusts temperature to improve night-time comfort, while hotel applications can integrate key-card systems to activate setback temperatures when rooms are unoccupied.
An integrated IR receiver enables seamless use with wireless remote controls, providing a neat and cost-effective solution for ducted units or installations without built-in IR capability, without the need for additional receiver kits.
