A complete 7-stage automated controller for mushroom compost Phase 2 pasteurisation and conditioning tunnels. Precision temperature, ventilation and fresh-air control with ammonia gas monitoring, intelligent sensor fallback, and full remote management — built specifically for the demands of compost conditioning, not adapted from a grow-room controller.
From leveling through pasteurisation, conditioning and cooldown — every stage runs on its own independently configurable setpoints, with automatic advance to the next stage as soon as conditions are met.
Every stage has its own fresh-air %, ventilation speed, target temperature, duration, ramp rate, and auto-advance setting — fully configurable, not fixed defaults. All setpoints persist through power cycles.
Compost pasteurisation and conditioning need more than a single thermometer — multiple sensing points, cross-checked against each other, plus gas monitoring that grow-room controllers don't typically include.
If a sensor fails mid-cycle, a basic controller either keeps trusting bad data or shuts down. This system automatically falls back through a prioritised chain of backup sensors — applying a correction offset where needed — and only flags "all sensors failed" if every option is genuinely exhausted.
A pasteurisation hold that silently restarts after a brief power blip can ruin a batch without anyone knowing until it's too late. This controller's hold timers are timestamp-based, so a configured clock means the pasteurise and condition hold timers survive power loss and resume exactly where they left off — not from zero.
Eight distinct alarm conditions, each independently configurable, with a dedicated alarm output relay and full alarm history logging.
Network connectivity, a built-in web dashboard, and cloud telemetry give you visibility and control without needing to be on-site.
