WaterFurnace Intellistart Reduce inrush current by 70%, reduce light flickering and go off grid!

Your geothermal system is an important investment, and you want it to last as long as it possibly can. What if there was a way to preserve the life of its compressor, reduce light flicker, and significantly diminish start-up sound from your unit? The WaterFurnace IntelliStart system will do all of this as well as make it easier to go “off-grid.”

As a compressor starts, it draws 5 to 10 times the amount of current it normally requires to run. This demand is called Locked Rotor Amps (LRA). The inrush of current and sudden startup can be stressful to the compressor and some electrical components. An IntelliStart system allows the unit to start using only 30% of normal amperage – far lower than other soft start solutions. You’ll reduce wear and tear on your compressor and protect it from potentially damaging low-voltage sags. Light flicker associated with your unit will be a thing of the past, and you’ll have a quieter system thanks to greatly diminished start-up sound.

The IntelliStart system also makes it easier to implement a back-up generator or off-the-grid power technologies like Solar PV and Wind. Many homeowners (and even some utilities) are forced to implement oversized electric generation systems to satisfy the momentary spike of starting amperage for HVAC equipment like furnace fans, air conditioners, heat pumps and geothermal units.

With IntelliStart, you’ll drastically reduce that demand and save money on standby generators and power generation infrastructure.

WaterFurnace's IntelliStart is a single phase soft starter which reduces the normal start current (LRA) by 70%. This allows the heat pump to more easily go "off-grid." Using IntelliStart will also provide a substantial reduction in light flicker, reduce start-up noise, and improve the compressor's start behaviour. IntelliStart is available in a field retrofit kit or as a factory option for all 5 Series and Synergy3D units

Intellistart Benefits

• Able to get compressors started under far worse conditions and with far lower starting currents than ever before.
• Conditions that other soft starters cannot come close to. Makes the heat pump supply voltage and line impedance tolerant.
• Reduces the supply line voltage drop experienced during starts. Protects the compressor from potentially damaging low voltage sags.
• Much lower start current, equating to further light flicker reduction - reductions appraoching 10:1 can now be acheived (over normal LRA).
• Provides a quieter unit with significantly diminished start-up noise.
• Easy to install for retrofit.

Features

• Compressors able to be started with even lower currents than before - typically 30% of normal starting amps.
• Automatic adjustment of the compressor starting current to the available supply voltage - maintaining constant starting torque and current.
• Supply line impedance monitoring and compensation.
• Automatic compensation for residual backpressure in the system.
• Monitoring of supply voltage while compressor is running to prevent motor stalling, causing excessive currents, under low voltage conditions.
• A compact, fully self-contained unit aimed at the single-phase compressor market, and is suited to both split systems and room models.
• Light flicker reductions of up to 10:1 over LRA under the same conditions.
• Totally self-contained, compact, and lightweight (5.12 x 2.56 x 2.17 in. and weighing less than 1.1 lb.)
• Housed in a flame-retardant ABS plastic enclosure.
• Enables easy installation either at the factory or in the field with full and detailed installation instructions supplied.
• CE and RoHs compliant.
• Proven performance in the field.
