I have a variable speed kithen exhause fan. Sometime people uses the range and don't turn on the fan.
I want to have the fan turn-on automatically at various speeds depending on needs.
I was thinking having a temperature sensor control the speed of the fan. Higher temp - higher speed.
spec: 120v fan
assumption: fan speed is varied by cutting the frequency.
question: is there small device (like a head pressure control by slowing down the condensor fan) that will vary the freq base on temp?
I would like to have some flexiblity in defining the range. For example; at < 95 degree, disable fan
at 95 degree, run at 10 hz
at > 120 degree, run at 60 hz.
this should be fun.
