The integrated installation of foot needs.Even if thermal protector is used simultaneously in the line, but NTC temperature-sensitive elements are also each with thermal protector
Put at one, the relative temperature error that the temperature that is collected is produced is larger, control temperature spot is forbidden, cause heater element dry combustion method or
The shortcomings of heating-up temperature is inadequate.
