The VIND Temperature & Humidity Controller turns a VIND EC silenced fan into something that runs itself. Set your high and low limits for temperature, humidity, or both, and the fan responds to live readings from a 3 m external probe. It is direct-wired — no WiFi, no Bluetooth, no app, no account and nothing to pair. Plug it in, set your thresholds, and it keeps working whether or not your phone, your router or your internet connection do.
No app is the feature, not the compromise
Plenty of climate controllers are app-first, and app-first has a cost people discover later: an account to create, a 2.4 GHz network to stay connected to, firmware that updates on its own schedule, and a device that stops behaving predictably the day any of that breaks. For a fan under a floor that simply needs to run when the air gets damp, that is complexity buying you very little.
This controller is wired to the fan and does its job in isolation. The thresholds live on the unit, the readings come from a probe on a cable, and nothing in between depends on a network. If your priority is a ventilation setup that still works in five years without being maintained, that is the argument for it.
Reading the air where it actually matters
The sensor is on a 3 m lead and the controller-to-fan cable is another 3 m, which means the box can be mounted somewhere you will actually look at it while the probe sits where the reading counts — the damp corner of the subfloor, the hot end of the roof space, the wall of the room rather than the ceiling void.
A large backlit display shows live temperature, humidity, the active mode and your setpoints at a glance, then dims itself after a period of inactivity. High and low alarms can be enabled if you want to be told when conditions go outside the band, and a controller lock stops the settings being changed by accident.
Four ways to run it
| Mode | What it does |
|---|---|
| AUTO | Runs the fan against your high and low temperature and humidity thresholds — the mode most subfloor and roof-space installs sit in |
| TIMER | Runs for a countdown period, then stops |
| ON | Continuous running at your set speed, ignoring conditions |
| OFF | Fan stays off regardless of readings |

FAQ
Will it work with a fan from another brand?
No. It is built for VIND EC silenced inline fans and connects to them directly — it is not a universal speed controller and will not drive a fan from another range. If you are running something else and want automated control, ask us before ordering rather than after.
Does it replace the manual controller that came with my fan, or work alongside it?
It replaces it. The manual PWM controller in the fan box sets a fixed speed; this one takes its place and adds the temperature and humidity logic on top of speed control. You do not run both.
Can it react to temperature and humidity at the same time?
Yes — the triggers are independent, so you can set either one on its own or both together. A subfloor usually runs on humidity, a roof space usually on temperature, and a garage often wants both.
Do I actually need it, or is manual speed control enough?
Manual is genuinely fine if your conditions are steady and you are happy to set a speed and forget it — the fan will run all day at 42 W or 90 W without complaint. The controller earns its place where conditions swing: a subfloor that only needs the fan after a wet week, a roof space that bakes in summer and does nothing in winter. It runs the fan when it will do something and leaves it off when it will not, which you cannot judge by feel from inside the house.
Where should the probe go?
Wherever the reading actually represents the problem — the dampest corner of the subfloor, the hottest end of the roof space — not next to the fan and not right by a vent, where incoming outside air will skew the reading. The 3 m lead is there to give you that choice while the controller stays somewhere accessible.
Can I mount it outside the space it is monitoring?
Yes, and it is usually the better arrangement. Two front screw slots let you fix it in the garage, the laundry or a hallway cupboard with the probe running into the subfloor or roof space, so you can read conditions and change settings without crawling anywhere.
Does it log history or graph anything?
No. It shows live readings and acts on them — there is no logging, no charts and no history, because there is no app. If you want recorded data over time, this is not the tool for it.
