🔌 Davey Spa Power SP601 2kW Control Box – Compact Spa Control System

Efficient electronic control pack designed for small to medium-sized spa pools with cost-effective functionality

📋 Product Overview

The Davey Spa Power SP601 with 2kW heater delivers reliable spa control in a compact, cost-effective package designed specifically for small to medium-sized spa pools. Manufactured by Davey Water Products in Australia, this controller provides essential management of pumps, blowers, ozone systems, and lighting within a space-saving enclosure.

The SP601 control pack features an integrated 2kW fluoropolymer-coated heating element housed within a durable engineering plastic heater tube. The heating element is protected for extended service life and corrosion resistance. Each SP601 includes an over-temperature cut-out device, a digital temperature sensor, an optical water sensor, and a controller circuit board with integrated isolating transformer.

With flexible pump configuration options supporting single or dual-speed pumps, optional circulation pump compatibility, variable speed blower support, and ozone output, the SP601 adapts to various spa configurations. The controller’s waterproof AMP connectors ensure reliable operation, whilst the poolside touchpad provides straightforward control with easy-to-read display.

The SP601 is supplied with a 5-metre power lead fitted with a 15A plug, making it suitable for standard electrical installations in smaller spa applications.

❓ Frequently Asked Questions

Q: Will this control box work with my spa? A: The SP601 2kW is designed for small to medium-sized spa pools. Compatibility depends on your spa’s electrical requirements and component setup. Contact Parts4Tubs with your spa model details for confirmation.

Q: What topside panel does this work with? A: The SP601 requires SP601-specific touchpads only. Compatible options include the SP601 Oval Touchpad or SP601 Rectangular Touchpad. SP800 and SP1200 touchpads are not compatible.

Q: Can I use a standard blower with a 2-speed pump? A: No. If you are using a 2-speed pump on Pump 1, only the Davey SPVSB variable speed blower can be used – standard blowers are not compatible in this configuration. If you need a circulation pump, 2-speed pump, and standard blower, consider the SP800.

Q: What is the difference between SP601 and SP800? A: The SP800 offers additional features including support for up to three pumps, higher maximum current (up to 40A), and multiphase capability. The SP601 is a more compact, cost-effective option for simpler spa configurations.

Q: Can I mount the SP601 vertically? A: Yes. The SP601 can be mounted with its heater tube vertical, but the water sensor must be at the top. Water must flow from the bottom to the top of the tube to force out all air.

Q: Does this include a topside panel? A: This listing is for the control box with integrated heater only. Touchpad sold separately – please add to your order if required.

Q: What warranty is included? A: The SP601 comes with a 2-year warranty. Refer to manufacturer terms and conditions.

Q: Does this require AMP connectors for my pumps? A: Yes. The SP601 uses AMP-style connectors for all peripheral equipment. If your existing equipment does not have AMP leads, you may need to purchase new leads separately.
