Davey SpaPower Q500AUS-20 Programmable Spa Pool Controller for Portable Spa Pools with Digital Display

Created for portable heated spa pool installations, the Davey SpaPower Q500AUS-20 combines electronic spa management and integrated water heating within a compact controller assembly suited to residential spa environments. Its poolside operating interface allows convenient adjustment of temperature and circulation settings while maintaining automatic control of connected spa functions during regular use.

The controller operates on a single phase 240V power supply and incorporates a 2.0kW heater for regulated water temperature management across portable spa systems. Automatic pump and heater control assists continuous circulation performance, while selectable demand heating and filtration heating modes allow operating behaviour to be configured according to spa usage requirements and user preference.

A digital temperature readout display provides clear operating feedback directly from the control interface during active operation. Programmable filtration timing can be adjusted between 0 and 15 minutes per hour to support controlled sanitation cycles, while integrated auxiliary air blower control manages compatible spa accessories. Optical and digital sensor technology supports accurate operational monitoring, and the self-diagnostic error code system assists troubleshooting when service attention is required.

Built specifically for portable spa pool applications, the controller incorporates IP24 rated enclosure protection suitable for installed spa equipment environments. Auto, pump, and heater indicator lights provide clear visual operating status during use. The compact housing measures 165mm high, 370mm wide, and 120mm deep, and is supplied with 40mm inlet and outlet plumbing connections for simplified integration into spa circulation systems.
