Grant Soft Start Module – HPAWSOFTC

Genuine Soft Start Unit for Grant Aerona³ Heat Pump Systems

The Grant HPAWSOFTC Soft Start Module is a genuine electrical accessory designed to reduce start-up current in Grant Aerona³ air source heat pumps. This module helps prevent power surges during compressor start-up, protects internal components, and reduces stress on the electrical supply—particularly important for installations on limited-capacity or sensitive power supplies.

Installing the HPAWSOFTC not only improves system longevity but also ensures compliance with electrical standards and reduces the risk of nuisance tripping or high inrush currents on start-up.

 Key Features & Benefits

• Official Grant Part – HPAWSOFTC
  OEM soft start module designed for integration with Grant Aerona³ heat pump systems.

• Reduces Start-Up Current Draw
  Smoothens compressor start-up by limiting high inrush current—protects internal and external electrical components.

• Ideal for Domestic Installations
  Particularly beneficial for properties with restricted supply ratings or rural grid connections.

• Pre-Wired for Easy Installation
  Simplified setup by heating engineers—no need for complex reconfiguration.

• Protects Heat Pump Lifespan
  Reduces wear on the compressor and minimises tripping of MCBs (Miniature Circuit Breakers).

• Supports MCS Compliance
  Helps meet Microgeneration Certification Scheme (MCS) recommendations for soft start installation in ASHP systems.

Compatible Grant Heat Pump Models

The HPAWSOFTC Soft Start Module is compatible with:

• Grant Aerona³ R32 Air Source Heat Pumps
  – Including 6kW, 10kW, 13kW, and 17kW models
  – Suitable for both monobloc and split configurations depending on installation setup

When to Install or Replace the Soft Start Unit

Install or replace the soft start module if:

• The system is experiencing frequent electrical trips on start-up

• You're installing a new heat pump in a domestic or off-grid setting

• The existing soft start unit is damaged or degraded from electrical wear

• You are working on a renewables retrofit or off-grid property

Adding a soft start module ensures stable, reliable start-up and extends the lifespan of electrical and mechanical components in your heat pump system.
