<p>I need a fan to be turned on at 8 and turned off at 18 every day during the workdays and to be turned off all over the weekend days. How should I implement it? </p>
<p>using the single speed fan, the fan is just turned on or off, but using the variable speed fan how it works? I mean that when the part load is in operation?</p>

<p>Thank you</p>
