⚡ Davey Spa Power SP800 2kW Control Box – Advanced Multi-Pump Spa Controller

Versatile mid-range control system with multiphase capability for medium to large spa pools

📋 Product Overview

The Davey Spa Power SP800 with 2kW heater delivers advanced spa control in a versatile package designed for medium to large spa pools requiring multiple pump support. Manufactured by Davey Water Products in Australia, this multiphase controller can operate on single phase (220-240V) or three phase (380-415V) power supplies, providing exceptional flexibility for various installation requirements.

The SP800 control pack features an integrated 2kW fluoropolymer-coated heating element housed within an engineering plastic heater tube. Inside every SP800 is one heating element leg, one over-temperature cut-out device, an optical water sensor, and a digital water temperature sensor. The controller PCB includes an integrated isolating transformer for safe low-voltage touchpad operation.

With support for up to three pumps (single or two-speed configurations), variable speed blower, 24-hour circulation pump, ozone system, and up to 60 LED lights via the daisy-chain system, the SP800 offers significantly more capability than the entry-level SP601. The multilingual LCD touchpad provides full programmability at the poolside, with text available in English, French, German, Dutch, Japanese, Spanish, or Portuguese.

The SP800 is supplied with oval touchpad as standard, featuring attractive built-in multicolour LED backlighting for easy night-time use and silicone gel potting for excellent water protection.

❓ Frequently Asked Questions

Q: Will this control box work with my spa? A: The SP800 2kW is designed for medium to large spa pools requiring multiple pump support. Compatibility depends on your spa’s electrical requirements and component setup. Contact Parts4Tubs with your spa model details for confirmation.

Q: What is the difference between SP800 and SP601? A: The SP800 offers significantly more features than the SP601 including: higher maximum current (40A vs 15A), support for Pump 1B outlet, LCD touchpad with multilingual display, up to 60 daisy-chain LED lights, three-phase capability, secondary touchpad support, and more comprehensive programmability options.

Q: What is the difference between SP800 and SP1200? A: The SP1200 adds Pump 2A and Pump 2B outlets (up to 5 pumps total), dual heater elements with dual thermal cut-outs, and is available in higher heater ratings (3.5kW, 4.5kW, 6.0kW). The SP800 supports up to 3 pumps and has a single heater element.

Q: Can I use a standard blower with a 2-speed pump? A: Yes, when using a 2-speed pump on Pump 1A, you can connect a standard single-speed blower to the AUX outlet. The SPVSB variable speed blower uses its own dedicated socket.

Q: Can I connect two touchpads? A: Yes. The SP800 has two touchpad sockets. You can connect two main touchpads, or one main touchpad plus the smaller secondary touchpad (6 buttons, no LCD) for pool-side control at a second location.

Q: Does this include a topside panel? A: Yes, the SP800 is supplied with oval touchpad as standard. Secondary touchpad available separately if required.

Q: What warranty is included? A: The SP800 comes with a 2-year warranty. Refer to manufacturer terms and conditions.

Q: Does this require AMP connectors for my pumps? A: Yes. The SP800 uses AMP-style connectors for all peripheral equipment. If replacing an SP750 with JJ plugs, you will need replacement AMP leads sold separately.

Q: Can I use three-phase power? A: Yes. The Q800-20 (2kW) model supports both single-phase (220-240V, 40A max) and three-phase (380-415V, 16A per phase) connections. Brown jumper leads must be removed for three-phase operation – see installation manual.
