Key Information

Product Information

Grant Wiring Centre - Compatible with Aerona³ R32 Models Only

The Grant EP001 Wiring Centre is designed to simplify and organise the wiring connections for multi-zone air source heat pump control systems. By bringing multiple connections together inside a single enclosure, it provides installers with a neater and more convenient way to manage the wiring associated with heating and domestic hot water zones.

Designed for Multi-Zone Heating Systems

The EP001 Wiring Centre can centralise wiring for up to four heating zones and one domestic hot water (DHW) zone. This makes it a practical choice for both new installations and retrofit heat pump projects where multiple heating zones need to be connected and controlled.

Simple and Organised Wiring

The wiring centre helps simplify connections when more than one heating zone and a DHW zone are being incorporated into the system. Housing the connections in one enclosure provides a more organised installation and makes the overall wiring arrangement easier to manage.

Zone Status Indicator LEDs

Built-in indicator LED lights provide a clear visual indication of whether a zone is active. This can make it easier for installers to identify the operating status of individual zones when checking or servicing the system.

Built-In DHW Priority

The Grant EP001 also incorporates domestic hot water priority, helping manage the relationship between heating zones and the DHW zone as part of a compatible system. This provides an additional level of control for multi-zone heat pump installations.

Compatibility

The EP001 Wiring Centre is compatible with the Grant Aerona³ R32 heat pump range only. It is not compatible with Grant Aerona 290 models, so the heat pump model should be checked carefully before purchase and installation.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.

If you're ordering multiple products from the same supplier, your order will be dispatched together once all items are ready. This means the longest lead time will apply.

If you need part of your order sooner, please call us on 01202 113233. We can arrange a split delivery, although an additional shipping charge will apply.
