Question: Our ventilation system is running faster at night time, is there something wrong?
Answer: Typically at this time of the year your home gets very hot and humid during the daytime, there is no point in bringing even more hot air down from the ceiling so the fan is operating very slow and in many cases will automatically switch off. Later into the evening and at night the ceiling cavity cools down and at some point the temperature in the ceiling will be lower than the temperature in the house. If you have your desired or target temperature lower than the current inside temperature then at this point the fan will increase in speed to bring the 'cooler' air down into the home to cool it down from its current temperature. Be mindfull that this will start happening when the ceiling temp is lower than the house temp, even at only 1 degree lower. This air typically will be less humid as well so it makes for a more comfortable environment than being hot and sticky, great for helping you get a more restfull nights sleep. If you do not want this happening then realise the system is only doing what you are asking it to do, to stop this then increase the desired temp level so the system does not go to cooling mode at night. Another point to be aware of, during peak summer time, there will be some nights when ceiling temp does not get lower than the inside temp in this case the fan speed will not increase and will stay in filtration mode. To conclude, the system is doing exactly as it has been designed to do and there is nothing wrong.
