ASCON MV3 MULTI VACTROL

Ascon MV3 Multi Vactrol Booster Pump Controller

The Ascon MV3 Multi Vactrol is a delay switch that automatically synchronises your pool cleaner booster pump with the filtration pump. Without a delay switch, your booster pump can start before the filtration pump is running — causing it to run dry and risk costly damage.

Key Features

• Delays booster pump start until filtration pump is confirmed running
• Prevents dry-running damage to your booster pump
• Compatible with modern chlorination systems with battery-backed timers
• Maintains correct pump sequencing even after power outages
• Suitable for pressure cleaner systems requiring a dedicated booster pump

Why You Need a Delay Switch

Modern chlorination systems feature built-in timers with battery backup, meaning they can restart independently after a power cut — but wall timers cannot. If your booster pump restarts before your filtration pump, it will run dry and may sustain serious damage. The MV3 eliminates this risk by intelligently managing the start sequence every time.

Frequently Asked Questions

What does the Ascon MV3 do?

The MV3 is a delay switch that synchronises your pool cleaner booster pump with the main filtration pump, preventing the booster pump from starting before water is flowing.

Will it work after a power outage?

Yes. Unlike standard wall timers, the MV3 maintains correct pump sequencing even after power interruptions, making it compatible with battery-backed chlorinator timers.

Which pool cleaners require a booster pump controller?

Any pressure-side pool cleaner with a dedicated booster pump — such as Polaris or Letro models — requires a delay switch like the MV3 to protect the pump.

Is professional installation required?

Electrical installation should be carried out by a licensed electrician. Refer to the installation manual and the video guide above.
