ETC-974 is a universal standard temperature controller with cooling, defrosting, and fan control outputs. The parameter setting of ETC-974  is divided into the user menu and administrator menu. If you are an equipment company, you can set up the administrator menu parameters. The end-user only sets the user parameter menu, which is convenient for users to operate. The administrator menu has a password protection function to prevent users from misusing settings.

It has a Copycard function, which is convenient to set the same parameter for a large number of temperature controllers. If you are an equipment manufacture or after-sale service company, this will save time.
