Davey Spa-Quip Spa Power 601 (SP601) 2.0kW Spa Controller with Rectangular Touchpad — Replaces SP600

The Davey Spa Power 601 (SP601) is the genuine replacement spa control system for the now-obsolete Spa Power 600 (SP600). This configuration is supplied with a 2.0kW heater and the rectangular touchpad, ready to restore full automatic control of your spa’s heating, filtration, pump, blower and light.

We keep these physically in stock for fast shipping or local pick-up, unlike most drop-shipping websites.

Genuine Davey Spa Power 601 Control System

From Davey’s long-running Spa-Quip SpaPower range, the SP601 runs on 230–240 V single-phase power and uses Davey’s optical water sensor and digital temperature sensor for reliable, accurate control. Bathers operate the spa from a sealed, safety extra-low-voltage (under 12 V) touchpad mounted on the spa shell — so there are no mains-voltage parts within reach of the water.

2.0kW Heater — Which Size Is Right for You?

This is the 2.0kW heater configuration, which draws approximately 8–9 A. A balanced, popular choice for most portable spas running on a 10 A circuit.

The controller automatically load-manages the heater against the pump and blower so the total draw stays within your supply. The simplest rule when replacing a failed unit is to match the heater size your spa was originally supplied with. If you’re unsure, check the rating printed on your old controller, or ask our team and we’ll confirm it for you.

Smart Temperature & Filtration Control

Set your ideal temperature from the poolside touchpad in 0.5°C steps, anywhere from 10°C to a maximum of 41.5°C (we recommend keeping spa water at or below 40°C). The SP601 then maintains it automatically. Choose Demand Heating (Ht.d) for fastest response, or Filtration-Only Heating (Ht.F) to limit cycling. Minimum daily filtration is programmable from 0 to 15 minutes per hour, and a one-touch 90-minute clean-up cycle is ready after every soak.

Works With Your SpaPower Pump, Blower & Light

The SP601 supports single-speed or two-speed jet pumps, with or without a near-silent 24 hour circulation pump for continuous filtration. It also drives a SpaPower air blower — including the variable-speed SPVSB with adjustable and oscillating modes — plus SpaPower LED lighting, whether the single-colour SPCL or the multi-colour SPVCL (12 colours plus white).

Oval vs Rectangular Touchpad

The touchpad is the sealed keypad mounted on your spa shell. This model ships with the rectangular touchpad. The controller electronics are identical across both shapes — simply choose the shape that matches your existing panel cut-out so it drops straight in. If your spa currently has the other shape, let us know and we’ll supply the matching pad.

• With time clock: 1.5kW · 2.0kW · 3.0kW

Built-In Self-Diagnostics

The SP601 constantly monitors itself and shows a clear error code if anything is wrong — from Er1 (no water / prime failed) to Er6 (thermal cut-out) and beyond. Most faults are recoverable by holding the Up, Down and Pump buttons together to reset. Not sure what a code means? Ask our team or use our Spa Error Code Finder for the full Davey list.

Upgrading From an Obsolete Spa Power 600 (SP600)?

The SP601 is the direct successor to the discontinued SP600, so it’s the correct upgrade path if your old unit has failed. You can usually identify an older system by the colour of its control box — earlier Spa Power units were housed in black cases, and some in blue. If you have a black or blue SP600-era controller, the SP601 is its modern replacement.

One important installer note: many original SP600 systems used the older Mini JJ plug connectors, while current Spa Power components use industry-standard AMP plugs. When upgrading, the plugs on your pump, blower and light leads may need to be changed over from Mini JJ to AMP to suit the new controller — a straightforward job for a spa technician. Ask us if you need the matching AMP connectors or advice.

Spa Power 601 systems are fitted to a wide range of Australian-made and imported spas. If you have a WWDG, SpaPro or similar spa originally supplied with a Davey SpaPower controller, the SP601 is the current genuine replacement.
