Cli-mate Fan Controller Smart – 3 °C hysteresis, 6.5 A

Cli-mate Smart Controller
Hysteresis preset at 3 °C • Adjustable minimum speed • Two rotary knobs • 5 m sensor

The Smart Controller sets the minimum ventilation speed and regulates the grow space temperature. Its distinctive feature: a hysteresis preset at 3 °C. Ventilation accelerates smoothly, in proportion to the temperature gap, reaching maximum once that gap hits 3 °C.

Two knobs, that is all: progressive regulation without having to configure a hysteresis band. It is factory-set to the value that suits most grow rooms.

Proportional regulation, not a switch

A conventional thermostat knows only two states. Here, speed is proportional to the temperature gap: half a degree above setpoint barely moves the fan, three degrees puts it at full speed. In between, everything is gradual.

Minimum speed, a setting not to neglect

The first knob sets the floor speed, the one that applies when temperature is within range. It should never go too low: without a permanent minimum flow, the carbon filter is no longer properly crossed and room air renews poorly.

A 5-metre sensor to measure in the right place

The 5 m cable lets you keep the unit accessible while placing the probe at canopy height. That is where the temperature the plants actually experience is decided, and it often differs by several degrees from a reading at floor level or near the door.

GrowLED tip :
Since the 3 °C hysteresis is fixed, pick this model if your room has normal thermal inertia. If temperature climbs very fast there — small volume, high lighting power — a controller with an adjustable band will give you more room to widen the span and smooth things further.
