Conversely, if the fan does not seem to be coming on even when you think the humidity is high, turn the trigger level down. However, fire doors should not be propped open. Recirculation units (including air conditioning) can mask poor ventilation as they just make an area more comfortable. The central heat and air unit is 2 years old. Natural ventilation can be provided through open windows, or through other means such as vents. 2. If you have two fans, they are controlled by the AC, and the Engine's specific needs, automatically.

If the sensor isn't working, your fan won't come on because it won't know that the temperature is hot enough to require activation, which can frequently lead to overheating. Natural ventilation can be used with heating systems to maintain a reasonable temperature in the workplace. HSE aims to reduce work-related death, injury and ill health.
