The Grant Aerona Smart Controller Kit For Smart Pre-Plumbed Cylinders (HP290SMARTPP) is the streamlined control package for installations pairing the Grant Aerona 290 R290 heat pump with a Grant QR2 Smart Pre-Plumbed cylinder. Because the QR2 Smart cylinder arrives factory-fitted with its own wiring centre and touchscreen display, this kit supplies only the additional components needed to complete the system: the Aerona Smart WiFi Hub, the outdoor weather sensor and two water temperature sensors.

Built For QR2 Smart Pre-Plumbed Installations
This kit is intended exclusively for use where a Grant QR2 Smart Pre-Plumbed cylinder is being installed with the Aerona 290. The cylinder is supplied with its own factory-fitted and pre-wired Smart Controller wiring centre and touchscreen display, so these components are not duplicated in this kit.
Not Interchangeable With HP290SMART
Do not confuse this kit with HP290SMART, which is the full kit (including wiring centre and touchscreen) required for standard, non pre-plumbed cylinder installations. Ordering the wrong kit will leave either a duplicate wiring centre or a missing display on site.
Qualified Installation Required
Installation and commissioning must be carried out by a qualified installer in accordance with BS 7671 IET Wiring Regulations and the Grant QR2 Smart Pre-Plumbed Cylinder installation manual (DOC 0217), which is supplied with the cylinder.
Factory-Ready Integration
Because the wiring centre and touchscreen arrive pre-installed in the QR2 Smart Pre-Plumbed cylinder, this kit completes the system without duplicating hardware – reducing both cost and installation time.
Remote App & Web Access
The Aerona Smart WiFi Hub connects the pre-wired controller to Grant's ecoNET24 platform, giving homeowners and installers remote visibility of system settings, performance data and error codes.
Accurate Weather Compensation
The outdoor weather sensor continuously feeds outdoor temperature data to the Smart Controller, allowing it to automatically adjust the heat pump's flow temperature for optimum efficiency.
Circuit-Level Water Monitoring
The two included water temperature sensors provide real-time and historical flow temperature data for connected heating circuits via the ecoNET24 platform.
Full Compatibility With Aerona 290 Range
Works across all five Aerona 290 models (4kW to 15.5kW), giving consistent smart control regardless of the heat pump size specified for the property.
Simple Sensor Installation
The outdoor sensor mounts easily to an external north-facing wall away from direct sun, while water sensors clip and insulate directly onto pipework – no specialist tools required.
