AHU Controller
AHU Controller, as name suggests, is designed specially to work as a Stand-alone Controller to control basic parameters such as Temperature & RH, as well filter clogging etc. of an “Air Handling Unit” (AHU). But what makes it unique is, it can be easily connected to &/ in a network and communicate with the Building Automation System on various Protocols such as PROFINET, Modbus in wired or wireless manner, at the same time, being very cost effective.
It has very precise Built-in T&RH Sensor and has a provision to add-on up to 3 differential pressure sensors. Apart from it, it has multiple Analog as well Digital Inputs and Outputs.
It has pre-programmed functions to control T&RH and display the same on a Touch Screen HMI. Other functions like Auto/Manual mode selection, setting of Alarm levels of parameters, etc. are very user friendly.
