🌬️ Grow Room AHU Controller

Mushroom Grow Room
AHU Controller

Industrial-grade AHU automation for mushroom grow rooms — precise CO₂, humidity and temperature control, with Manual, Semi-Automatic and Fully Automatic (AI) modes for both the fresh-air damper and ventilation (VFD). Monitor and control from anywhere with live mobile access and scientific trend graphs.

Field-Tested for 1 Year — 2,900+ Live Parameter Combinations

Before release, this control system was run continuously for a full year against constantly varying live temperature, CO₂, and humidity conditions — exercised across more than 2,900 distinct combinations of those parameters. That's the difference between a controller that works in a demo and one that holds up through every season, every load condition, and every edge case a real grow room throws at it.

Environmental Sensing

Precision Sensing, Wide Operating Range

Dual RTD-class temperature probes, CO₂ concentration sensing, and relative humidity sensing — individually calibratable, covering an operating range built for real-world grow room extremes, not lab-ideal conditions.

T1
Air Intake Temperature (PT100)
// 0-50°C · HIGH ACCURACY RTD
High-accuracy PT100 RTD probe measuring grow room air temperature. Drives the active control logic for heating, cooling, and compressor staging across the full 0-50°C operating range.
T2
Substrate / Bag Core Temperature (PT100)
// FIELD-CALIBRATABLE
A second PT100 probe inserted into the growing substrate, individually calibratable in the field via 2-point or multi-point calibration — no factory recalibration required.
CO₂
CO₂ Concentration — Active Control Logic
// 100-40,000 PPM
Continuous CO₂ measurement across a 100-40,000 ppm range, far wider than standard mushroom controllers. Active control logic governs damper and ventilation response to keep respiration conditions on target at every stage.
RH
Relative Humidity
// 10-98% RH
Relative humidity sensing across a 10-98% range, driving humidifier/dehumidifier relay control with mutual-exclusion safety logic — the two outputs never fight each other.
Automated Climate Control

Damper, VFD & Compressor Staging — All Three Modes

The fresh-air damper and ventilation drive (VFD) both support Manual, Semi-Automatic, and Fully Automatic (AI) operation — with multi-priority safety logic and an anti-drift safeguard that most mushroom controllers don't have.

FRESH-AIR DAMPER
🌀

Motorized Damper Control

ManualCO₂ Semi-AutoFully Automatic (AI)
Multi-priority safety logic: temperature-emergency force-close, CO₂-emergency force-open. Configurable ramp rate for smooth, gradual positioning instead of abrupt jumps.
Anti-drift safeguard: full-duration recalibration close cycle eliminates position-sensor drift that could otherwise leave the damper physically open while reported closed.
VENTILATION (VFD)
⚙️

Variable Frequency Drive Control

ManualSemi-AutomaticFully Automatic (AI)
Load-based speed lookup table responds to 0/1/2/3-compressor and heating states. In Auto mode, proportional temperature trim and damper-position speed boost fine-tune ventilation in real time.
Driven via industrial serial fieldbus to the VFD — not a simple on/off relay.
COMPRESSORS
🔄

Up to 3 Staged Compressors

Independently staged compressors with automatic rotation scheduling — distributing runtime evenly to extend equipment life, rather than always running the same unit first.
Heater control includes a safety interlock: never runs simultaneously with active cooling.
HUMIDITY CONTROL
💧

Humidifier / Dehumidifier

Mutual-exclusion safety logic prevents the humidifier and dehumidifier from ever running against each other. Configurable hysteresis per control loop prevents short-cycling.
Hysteresis configurable independently for every control loop.

Setpoint Ramping — Smooth, Not Sudden

Every setpoint change — temperature, humidity, or CO₂ — transitions gradually at a configurable rate instead of jumping instantly to the new target. This isn't a minor convenience feature: sudden setpoint jumps shock both the mechanical systems (compressor short-cycling, damper slamming) and the biological system in the room (mycelium and fruiting bodies respond poorly to abrupt environmental shifts).

Configurable Rate Per ParameterSet independent ramp rates for temperature (°C/hour), humidity (%/hour), and CO₂ (ppm/hour)
Avoids Mechanical Shock-LoadingGradual transitions reduce compressor short-cycling and abrupt damper/VFD movement
Avoids Biological Shock-LoadingSmooth environmental transitions instead of sudden shifts that stress mycelium and fruiting bodies
Works With Startup Anti-Jerk ProtectionIndependently configurable startup delay per output staggers compressor/heater inrush current after a power interruption
