General Information

This UCM-CLD chiller control is
composed of eight electronic
modules, which each have their
own 115V or 24V power supply and
communicate with each other via a
serial link. The names of the
modules are linked to their
functions.
Functions
Safety, protection, and control of the helical-rotary compressor and
its components
Safety, protection, and control of the chiller
Control of both electronic expansion valves
, Control of the serial communication, unit external setpoints and
ice-making mode (optional module)
Operator interface located in the front panel of the unit
Operator interface located up to 1500m from the unit, able to
communicate with up to four units of the same type (optional module)
Protection of the internal communication bus in the unit from external
interferences (optional factory-mounted module, compulsory when
using a Remote CLD)
Interface between the control of the unit and a Building Management
System using Trane COMM 3 serial link
