Grant Aerona 290 Control Range
Grant Aerona Smart Controller Kit – HP290SMART
A complete smart control package for Grant Aerona 290 R290 air source heat pumps, offering weather compensation, multi-zone heating control and remote system monitoring for standard-cylinder installations.
The Grant Aerona Smart Controller Kit (HP290SMART) is a dedicated heating and hot water control package designed for the Grant Aerona 290 R290 air source heat pump range. Supplied with a 4.5-inch colour touchscreen display, controller wiring centre, Wi-Fi hub and temperature sensors, it provides installers with the components needed to configure and manage a conventional heating system using a standard, non-pre-plumbed hot water cylinder.
With integrated weather compensation, the controller monitors outdoor temperature and adjusts the heat pump's flow temperature to support efficient, consistent heating. It can manage up to three independent heating circuits alongside domestic hot water, making it suitable for properties with different heating requirements, including radiator and underfloor heating zones.
The included Aerona Smart Wi-Fi Hub connects the controller to Grant's ecoNET24 app and web portal, allowing homeowners and installers to view system settings, performance information and error codes remotely. Additional features include heating and hot water schedules, anti-legionella cycle support, installer configuration assistants and compatibility with wired and wireless room thermostats, available separately.

The HP290SMART kit is designed for use with a standard, non-pre-plumbed cylinder. If you are installing a Grant QR2 Smart Pre-Plumbed cylinder, use the HP290SMARTPP kit instead. According to the supplied product information, the pre-plumbed version is factory pre-wired and does not require the wiring centre or touchscreen display to be purchased separately.
