Automated Environmental Control Systems In Composting And Mushroom Growing

RT4-02F Controller for Phase I Composting in Open Bunkers

image

RT4-02F controller is used for phase I composting in open or half-open bunkers with roof. In automatic mode the controller calculates average compost temperature by three points and compares it with a set-point. By the difference between a current average and set temperature, as well as depending on ambient temperature, the controller generates an output signal to control the fan. The controller also has a built-in timer for setting a period and time of the fan activation in manual control mode.

RT4-02F can be connected to PC via RS485 communication interface. TechnologSoft Musroom Edition software enables control of environmental parameters and displays all alarm situations on your PC.
