Setting Temperature Thresholds to Auto Turn On/Off AC & Misting — iNut LCD HuTem

Mushroom growing houses need to keep the microclimate within a narrow range: temperature 25–27°C and humidity 70–80%. The iNut LCD HuTem device lets you pre-set these thresholds, then automatically controls the air conditioner (cooling) and the misting system (humidifying) by closing/opening the connected contact points. You just need to wire the device to the correct contact points as instructed — the rest of the operation is fully automated.

A simple yet effective logic (with hysteresis to prevent oscillation): when the temperature reaches 27°C → TURN ON the AC to cool down; when it drops to 25°C → TURN OFF the AC. Thanks to the 25–27°C buffer zone, the unit doesn't switch on/off constantly, so it lasts longer and saves power.

Similarly for humidity: when humidity drops to 70% → TURN ON misting to add moisture; when it reaches 80% → TURN OFF. The environment always stays within the ideal humidity range, so the mycelium grows evenly.

The iNut LCD HuTem reads the temperature-humidity sensor, then closes/opens the corresponding contact points (relays): one contact for the air conditioner, one contact for the misting pump. Just wire it correctly as instructed and you're done.

Sensor → threshold comparison on HuTem → device on/off → environment changes → sensor reads again. The loop runs continuously to keep the microclimate stable:
