STM is a specialized controller channel microprocessor controller for controlling devices are required to control both temperature and humidity. The controller has two additional relay outputs controlled from the front panel keys. Can be used to control additional functions such as enabling lighting equipment, running fans, etc. The controller can also be equipped with a galvanically isolated interface RS485 MODBUS ASCII allowing communication with other devices as well as with PC.
