About the AHU Controller - Mushroom Farm
The air handling unit is the heart of every AC mushroom room. When its damper, fan, chiller and humidifier are adjusted by hand, climate swings between shifts and crops suffer. The MychoAI AHU Controller runs all of them together from one set of sensors and one recipe.
Each room follows a stage-wise programme — spawn run, case run, pinning and flushes — with smooth ramps between targets. Growers can run it fully automatic, semi-automatic, or take manual control whenever they want.
Simple, automatic, reliable
Measure
Twin temperature probes (air and compost), humidity and CO₂ sensors read the room every few seconds.
Compare
The controller compares live values with the stage recipe and the ramp in progress.
Adjust the AHU
Damper position, fan speed, cooling, heating and humidity are adjusted together — never fighting each other.
Report
Every change is logged. Growers see trends and get alerts on their phone.
Everything it does for you
Environmental sensing
- Dual PT100 probes for air and compost temperature
- CO₂ sensor up to 20,000 ppm for spawn run
- Relative humidity sensor for high-humidity rooms
- Field calibration from the touch screen
Automated AHU control
- Motorised fresh-air damper with automatic re-calibration
- AHU fan speed through VFD (Modbus or 0–10 V)
- Chiller valve or up to 3 staged compressors with rotation
- Heater, steam and humidifier with interlocks against over-lap
Recipes & ramping
- Ready recipes for button, oyster and speciality mushrooms
- Gradual set-point ramps in °C/hour, %/hour and ppm/hour
- Automatic hand-over from spawn run to case run and pinning
- Flush counter and day-wise crop calendar
Monitoring & safety
- 7-inch touch screen at the room door
- High / low alarms for every value, sensor-fault detection
- Keeps running the recipe if the internet is down
- Role-based access for owner, manager and grower

Where it is used
Common questions
Will it work with my existing AHU?
Yes, in most cases. We survey your AHU, damper and chiller set-up first and add only the actuators or VFD that are missing.
Can the grower still control things by hand?
Yes. Every output can be switched to manual from the touch screen or app, and the controller returns to auto when you choose.
What if the power or internet goes off?
Recipes and settings are stored in the controller. After a power cut it restarts the recipe on its own; without internet it keeps working and syncs data later.
Can I copy one room's recipe to other rooms?
Yes. Recipes can be saved, copied and adjusted for each room from MychoCloud.
