Product Information

Grant HP Wiring Interface - Compatible with Aerona³ R32 Models Only

The Grant EP002 HP Wiring Interface is designed to provide the volt-free switching required for compatible Grant Aerona³ R32 air source heat pump systems. It works with the heating and hot water switched-live outputs from the heating system wiring centre, providing a practical interface between the heating controls and heat pump.

Designed for Aerona³ R32 Heat Pumps

The EP002 has been specifically designed for use with the Grant Aerona³ R32 heat pump range. It provides the required interface for the heating and hot water control signals, helping the heat pump system respond correctly to the connected heating controls.

Flexible Installation Options

The interface box can be installed next to the heating system wiring centre or positioned closer to the Aerona³ heat pump, giving installers flexibility when planning the system layout. However, the EP002 must not be installed externally and should be positioned in a suitable protected location.

Convenient Installation Pack Option

The Grant EP002 can be ordered individually when required or supplied as part of Grant's Heat Pump Installation Pack. This provides flexibility depending on the requirements of the installation and the components already available.

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.

Multiple Products from the Same Supplier

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.
