Operating control and regulation 5 speed Standard controller. This controller provides a 5-stage speed regulation by voltage modulation totally interference free, motor noises and vibrations free. All connections, both the input and the control, are placed outside the equipment. For a simple connection free of errors, between the controller and the equipment there is used a telephonic type cable with connectors RJ45, what reduces sensibly the installation time. The digital communication with the controller increases the protection against interferences and allows long distances (till 300m) between...

Operating control and regulation Electrical heating 5 speed controller Besides the standard controller functions, It allows to regulate the heating in 3 stages. There can be limited the power of the heating stages according to the fan’s speed. (Air-flow). Interface box to a centralized controller The CT-PLC-NE interface connects the digital controller of the equipment to a centralized digital management DDC, PLC, BMS, etc. type. With the direct programming we can control all the equipment functions.
