CMU – Controller Main Unit

The Controller Main Unit (CMU) is fully programmable and is suitable for Building Control Systems, Environment Control Systems and HVAC Control Systems. The CMU, being fully programmable, promises control & monitoring application versatility, as it allows the specific application to be created according to each facility or application requirements.

The controller is based on a PIC microcontroller with 2-RS485 communication Bus. It has a combination of digital input, digital output, analogue input and analogue output. Its LEDs indicators are effective in monitoring the Digital Input, Digital Output, Heartbeat, Upstream communication and downstream communication. Onboard fuses are included to prevent overcurrent and surge.

CMU is designed with flexibility and cost-effective data acquisition in mind. The Diagram Type DLC programming tool consists of complete functions such as PID lead-lag and A-D conventions that eases the user to program any kind of requirements.
