The purpose of the C35‐CBMS device is centralized control and operation of different HVAC zones in buildings containing C35‐VAV or C35‐FC devices.

The C35‐CBMS can control up to 8, 16, 24 or 32 devices (C35‐FC or C35‐VAV) depending of the C35-CBMS model type. With it you can monitor all information that you can find on C35‐VAV or C35‐FC device’s Home Screen. The C35‐CBMS provides control over various parameters:

  • On the C35‐VAV:
    • Working and operating mode
    • Temperature set point
    • Relative humidity set point
    • CO2 set point
  • On the C35‐FC:
    • Working and operating mode
    • Temperature set point
    • Fan speed set point

Also, the C35‐CBMS has the option to completely take command over a remote device’s Working and operating mode. With this option you have the ability to change the Working and operating mode for multiple devices at once, or to set up just one scheduler, the scheduler on the C35‐CBMS, and all other devices will follow it. This feature, the Remote Controlled feature, can be enabled or disabled separately for each registered device.
