MLM Controls – Multi-loop Modular Controls

MLM+

MLM or Multi-Loop-Modular Controls were born from over 30 years of VAV diffuser experience and Rickard’s vision to enhance the benefits of VAV diffusion. Comfort can be customised for large zones or specific individuals, powerful diffuser management software gives the user complete control over an entire buildings’ diffusers, intelligent energy saving software and hardware enhances energy savings and the modular benefits of VAV diffusion are maximised to allow complete layout flexibility without adding unnecessary cost.

Rickard’s modular controls also allow hardware modularity, and a number of diffuser accessories are available that are easy to fit to a diffuser. They include remote temperature control (wired & wireless), top up neck heaters and airflow sensors (for commissioning, airflow trimming and air-conditioning billing calculations).

The MLM+ upgraded controls specification allows for standard on-board sensing and occupancy sensing on every VAV ceiling diffuser (VCD, VSD, VRD, VSW & VRW).

Our MLM control system can communicate with the Building Management System to give the administrator full centralised control of the HVAC system. By using our MCU, the cost of connection to a BMS can be reduced considerably. It does this by centralising the BMS access point and by connecting to, up to 60 diffusers/MCU.

For smaller installations we provide the option of BMS interfacing on our PSU. This iPSU will provide seamless BMS interaction for up to 15 diffusers.

Our AHU (Zone) controller is also highly configurable and easily integrates with the Rickard diffuser network without the time-consuming programming requirement of traditional controllers. It has been designed to make the setup, testing, monitoring, scheduling and management of an HVAC system quicker, easier and more affordable than ever.
