Cli-Mate Smart Controller

The Cli-Mate Smart Controller is a proportional, stepless fan speed controller that increases ventilation smoothly and progressively in response to rising grow room temperatures. Unlike 2-step systems, it delivers continuous, gradual fan speed adjustment without abrupt switching — ideal for temperature-sensitive crops. With a 6.5A capacity, a programmed hysteresis of 3°C and a 5-metre external temperature probe, the Smart Controller brings professional-grade climate precision to any indoor grow setup. Plug & Play installation, two knobs, no configuration complexity. Discover the Smart Controller at plantandflower.be.

Cli-Mate Smart Controller — Proportional Fan Speed Control for Precision Grow Room Climate Management

Temperature fluctuations in the grow room demand a measured, continuous response — not abrupt switching. The Cli-Mate Smart Controller delivers exactly that: a proportional, stepless fan speed regulator that increases ventilation smoothly and progressively as the temperature rises. A step forward from 2-position controllers in Cli-Mate's climate control range, it is designed for growers who want stable, precise environmental control without complex setup.

Proportional Control — What It Means in Practice

The Smart Controller does not simply toggle between two speeds. It continuously modulates fan speed in proportion to the measured temperature. As the grow room heats up, the fan gradually accelerates toward maximum speed. As the temperature drops, it eases back down. The built-in 3°C hysteresis prevents the controller from reacting to every minor fluctuation, eliminating constant on/off cycling that shortens fan lifespan and disturbs the grow environment.

Proportional, stepless fan speed regulation: continuous modulation based on real-time temperature data.
6.5A capacity: handles more powerful extraction fans than standard 4A controllers.
Programmed 3°C hysteresis: stable regulation without unnecessary switching cycles.
5-metre external temperature probe: accurate measurement at the most relevant point in the grow space.
IP44 protection class: splash-proof for humid grow room conditions.

Advanced Performance, Minimal Complexity

Despite its sophisticated control mechanism, the Smart Controller requires only two adjustments: a dimmer knob for minimum fan speed and a thermostat knob for the target temperature threshold. No digital menus, no programming routines. Plug & Play installation means the controller is operational in minutes — connect the temperature probe, plug in the fan and the Smart Controller manages the rest autonomously.

Choosing Between the Smart Controller and Fan-Controller

For a simpler 2-step ventilation solution, the Cli-Mate Fan-Controller is the straightforward choice. For an all-in-one unit that also manages lighting and heating alongside ventilation, the Cli-Mate Mini-Controller 7A centralises full grow room management.

What is the difference between the Cli-Mate Smart Controller and the Fan-Controller?

The Fan-Controller switches between two fixed fan speeds based on a set temperature threshold. The Smart Controller modulates fan speed proportionally and continuously as the temperature changes — a smoother, more precise response without abrupt speed switching.

What does the 3°C hysteresis on the Smart Controller mean?

The 3°C hysteresis prevents the controller from reacting to every minor temperature fluctuation. It creates a buffer zone around the set point, avoiding constant on/off cycling of the fan — which extends fan lifespan and delivers a more stable grow room climate.

Which fans are compatible with the Cli-Mate Smart Controller?

The Smart Controller supports up to 6.5A, making it compatible with more powerful extraction fans than standard 4A controllers. Always verify your fan''s current draw before connecting to avoid overloading the unit.

Can I set a minimum fan speed on the Cli-Mate Smart Controller?

Yes. The dimmer knob sets the minimum fan speed — the baseline ventilation level that runs continuously even when the temperature is below the set threshold. This ensures permanent minimum airflow in the grow room at all times.
