Good afternoon! My name is Mike and I am a student working towards my hvac degree. I am currently learning about fan/limit control switches and was wondering what the proper fan- on and fan -off switch temperature settings should be on a honeywell L4060 fan limit control switch? Also, do these temperature setting remain constant with any brand of limit control switches or does it vary depending on the manufacturer? Thanks for the help!! Mike ---
