The Types of Ventilation Control

March 14, 2018

There are four main ventilation control options that you can get which will control your intermittent fan, which creates the flow of air through your ventilation system. Each different type of control is designed specifically to meet a different need of the user. The four typical control types are basic, timer, humidity, and motions sensor.

For these controls, there are different pros and they meet different needs that might be present in your space.

Basic Ventilation Control

A basic control is the simplest form of control for your fan and overall ventilation system. It allows you to turn the system on and off, as basic as it comes in terms of functionality. This is either controlled by a remote switch or with a switch that is like a typical light switch. Basic control is ideal for a ventilation system where you want complete, third party, control of the system. Which means that the system is tailored to your exact needs and schedule, rather than following the preprogramming of the ventilation unit.

Timer Ventilation Control

Timer control, as it sounds, is quite simple. It means that the fan in your ventilation system will continue to run after being switched off, for a predetermined length of time. This time can vary from as little as two minutes to forty-five minutes, depending on your needs. As a design, it helps to ensure that all excess moisture is removed from the system after use and does not build up once the ventilation is turned off.

A timer ventilation allows for a small level of automation to the process. As you don’t have to worry about turning it off too soon, etc. But it also maintains a certain level of control over the whole system.

Humidity Ventilation Control

Humidity system timers for ventilation control mean that your fan will turn on as soon as humidity levels meet a pre-set level. The system will continue to run until the humidity levels fall below this threshold once again. Again, the fan will continue to run even after the humidity levels lower to ensure that excess moisture is removed from the system. Typically, you can set the control between 40% and 90% humidity.

A humidity fan is typically used, domestically, in a kitchen or a bathroom. As such, it should only be used in a commercial setting where the activity taking place will cause the moisture in the room to rise. As when this happens it can lead to damp or even mould.

Motion Ventilation Control

Finally, there is the motion timer system for your ventilation system. This, again, is a very simple idea. Whenever the room is in use and the motion sensors are triggered, the ventilation system will turn on and continue after people have left the room, again to remove excess moisture. This type of system is basically on-demand, making it efficient for money saving purposes.


Choosing the right system for your working needs depends on your workplace and the activities that take place there. These systems allow for different levels of control, working environments and even budget, depending on your needs. You simply need to choose the best for your business.
