Grant Aerona 290 Smart Controller Kit For Standard Cylinders

Description

The Grant Aerona Smart Controller Kit (HP290SMART) is the standard-cylinder control package for the Grant Aerona 290 R290 air source heat pump range. Built around Grant's 4.5" colour touchscreen display and dedicated wiring centre, this kit gives installers full weather-compensated control of heating and hot water when the Aerona 290 is paired with a conventional (non pre-plumbed) cylinder. The kit includes the Aerona Smart WiFi Hub for remote monitoring and control via the ecoNET24 app or web portal, along with the outdoor and water temperature sensors required for accurate, real-time system performance data.

Standard Cylinder Compatibility

This kit (HP290SMART) is designed for use with the Aerona 290 heat pump alongside a standard (non pre-plumbed) cylinder. If installing with a Grant QR2 Smart Pre-Plumbed cylinder, use the HP290SMARTPP kit instead, which is factory pre-wired and does not require the wiring centre or touchscreen display to be purchased separately.

Qualified Installation Required

Installation must be carried out by a suitably qualified installer in accordance with BS 7671 IET Wiring Regulations. The controller is not an intrinsically safe device; mains power must be isolated before any wiring work and the unit must not be installed in a bathroom or shower room.

Modbus Connection to Heat Pump

The Smart Controller communicates with the Aerona 290 via a 2-core Modbus connection between the heat pump's H1/H2 terminals and the wiring centre's G2 socket. Wiring polarity must be matched exactly – refer to the Aerona 290 installation manual (DOC 0204) for the correct terminal diagram.

Weather Compensation

Continuously monitors outdoor temperature via the supplied weather sensor and automatically adjusts the heat pump's flow temperature to maintain efficient, consistent comfort without user intervention.

Multi-Zone Heating Control

Supports up to three independent heating circuits plus domestic hot water, each with its own heating curve, ideal for homes with mixed radiator and underfloor heating zones.

Remote App & Web Access

The included Aerona Smart WiFi Hub connects the controller to Grant's ecoNET24 platform, giving homeowners and installers remote visibility of system settings, performance data and error codes from a phone or browser.

Installer & User Assistants

Built-in configuration wizards guide installers through system setup and commissioning, while ongoing monitoring tools support long-term diagnostics and maintenance.

Legionella & Time Scheduling

Native anti-legionella cycle support and flexible time schedules for heating and hot water circuits, configurable directly from the touchscreen or the ecoNET24 app.

Compatible Thermostats

Works with both wired and wireless room thermostats (available separately), maintaining precise room-by-room temperature control across all connected zones.

Frequently Asked Questions

Which Aerona 290 models is this kit compatible with?

The HP290SMART kit is compatible with all five Aerona 290 models (4kW, 6.5kW, 9kW, 12kW and 15.5kW).

Do I need this kit if I'm installing a Grant QR2 Smart Pre-Plumbed cylinder?

No. The QR2 Smart Pre-Plumbed cylinder comes factory-fitted and pre-wired with its own controller components. For that cylinder type, order the HP290SMARTPP kit instead, which contains only the Wi-Fi Hub, outdoor sensor and 2 water temperature sensors.

Can this controller run multiple heating zones?

Yes, the Smart Controller supports up to three independent heating circuits in addition to domestic hot water, each with its own heating curve and time schedule.

Is remote access included?

Yes. The kit includes the Aerona Smart WiFi Hub, enabling remote monitoring and control via the ecoNET24 mobile app or a web-based portal.

Does this kit include flexible hoses and isolation valves?

No. Hose kits (uninsulated or Primary Pro insulated) are ordered separately as HPHOSEKIT or HPHOSEKITPRO.
