Cli-mate Dual-Flow Controller Twin Humi – humidity, 8 or 24 A

Cli-mate Twin Controller Humi
Two independent outputs • Negative pressure • Humidity • Dual sensor • 4+4 A or 12+12 A

This version of the Twin Controller adds humidity regulation to separate intake and exhaust control. It relies on a dual sensor, reading temperature and humidity at the same point, covering 5 to 55 °C and 20 to 100 % relative humidity.

One probe for two readings: temperature and humidity measured at the same spot, so the setpoints are genuinely consistent with each other.

Temperature and humidity measured at the same point

Using two separate probes risks regulating on two places that do not match. The dual sensor reads both quantities at the same spot: the unit’s decisions then rest on a real air state, not an average between two different zones.

A wide range, up to 100 % humidity

Stated coverage runs from 20 to 100 % rH and 5 to 55 °C. The top of the humidity range matters: late in flower, with a heavy canopy, air can approach saturation. A device that gives up beyond 90 % leaves you blind at the most critical moment.

The differential prevents short cycling

With a 1 °C per step differential, the unit does not switch every time the reading wobbles by a tenth around the threshold. Connected appliances start less often, last longer, and the climate stays steadier.

Two versions, chosen per output

As on the standard Twin Controller, ratings apply per output: 4+4 A (8 A total) and 12+12 A (24 A total). Check each motor’s draw separately before choosing.

GrowLED tip :
Place the dual probe inside the canopy, not above it: that is the only spot where the humidity reading reflects what the flowers actually experience. You also gain a truer temperature reading, since that is where air moves least.
