SPA-CONTROL replaces your analogue spa controller with a modern WiFi-connected system — monitor and control from anywhere, protect your equipment, and cut running costs.
This will replace all previous models of the Davey Spa-Quip SP600 & SP601 PCBs.
Every relay switches at the AC zero-voltage point — eliminating arcing, contact pitting, and EMI. Delivers 3–10× longer relay life and prevents heater relays from welding closed.
Full web interface — no app download required. Adjust temperature, switch heating modes, set schedules, and monitor your spa from any phone, tablet or computer.
Battery-backed real-time clock with per-day wake and sleep times. Heater and pump switch off automatically outside active hours — no energy wasted overnight.
Choose between Demand Heating (always ready) or Filtration-Only mode — heater runs only during scheduled filtration cycles, cutting electricity costs significantly.
Detects welded relays, open Klixon thermal cutouts, water loss, sensor faults, and over-temperature conditions. Error codes stored across power cycles for faster technician diagnosis.
Over-the-air updates mean new features and bug fixes are delivered remotely — no site visit required. Your controller improves over time.
DS18B20 digital sensor with CRC verification and outlier rejection. Immune to cable noise and voltage drop — no drift, no field calibration needed.
Controlled relay sequencing when switching pump speeds eliminates inrush current spikes and mechanical shock — extending motor and winding life.
Hardware flash encryption on every production unit. Firmware cannot be read from the chip — protecting your investment and our intellectual property.
A dedicated Ready mode will bring your spa to setpoint temperature exactly when you need it — using a self-learning algorithm that optimises turn-on time based on your usage patterns and local weather conditions. The longer you use it, the smarter it gets. Spa ready when you are — without wasting energy heating it all day.
