Description
Module B supplements the range of functions performed by regulators R.Control, R.Control TOUCH and S.Control TOUCH. The module cannot operate as a standalone device. The use of the module and the functions it performs depend on the main regulator with which it cooperates. All settings for the module are made in the main regulator.
