Communication
interface modules
The CIM modules enable
communication of operating data, such
as measured values and setpoints,
between Hydro MPC and a building-
management system.
Note: CIM modules must be fitted by
authorised staff. The CIM module
enables transfer of data such as:
• operating mode
• setpoint
• control mode
• warnings and alarms
• power/energy consumption.
We offer the following CIM modules:
