A regulator for controlling heating systems. Especially recommended for protection against freezing and maintaining the desired temperature of the pipeline. It has two freely configurable relays and a TTL connector that gives the option of connecting the BusAdapter module with the RS-485 bus or Unicard with a USB connector. The controller works with BMS systems using the protocol in ModBus, Televis or analogically using the relay operating in the alarm mode. It consists of a controller and a temperature sensor for mounting on the pipe surface.
