This question already has an answer here:
as the title: i have a room with with a heat generation that i need to keep under a certain temperature. Anyhow, i want to grant a minimum of air circulation even if the temperature is not reached (winter scenario) and i thought it can be a good idea to connect a thermostat and a timer in parallel to the air extractor (set for 10 minutes every 2/3 hours for example). In this scenario, if the temperature is reached, the fan is working thanks to the thermostat, if is not reached for as long as 2 hours, the fan is activated by the timer.
Thanks for help!
