Description
Everything your existing controller can’t do
Solar Battery Storage integration.
Monitors your solar inverter and switches your spa pool on when there is surplus power available.
⚡
Zero-Crossing Relay Switching
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.
📱
Control From Anywhere
Full web interface — no app download required. Adjust temperature, switch heating modes, set schedules, set solar battery storage threshold and monitor your spa from any phone, tablet or computer.
🕐
Weekly Schedule
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.
🔋
Energy-Saving Heating Modes
Choose between Demand Heating (always ready) or Filtration-Only mode — heater runs only during scheduled filtration cycles, choose to run when surplus solar power available cutting electricity costs significantly.
🚨
Advanced Fault Detection
Detects welded relays, open Klixon thermal cutouts, water loss, sensor faults, and over-temperature conditions. Error logs stored across power cycles for faster technician diagnosis.
🔄
Remote Firmware Updates
Over-the-air updates mean new features and bug fixes are delivered remotely — saving expensive site visits. Your controller improves over time.
