Standard Control Features
Human Interface (HI) Panel
The Human Interface (HI) Panel provides a 2 line X 40 character clear English language liquid crystal display and a 16 button keypad for monitoring, setting, editing and controlling.The Human Interface Panel is mounted in the unit’s main control panel and is accessible through a hatch built into the unit’s control panel door.
The optional
The Main Menu of the Human
Interface panel:
STATUS — used to monitor all temperatures, pressures, set points, input and output status.The CUSTOM KEY will have four reports that can be user defined.The report screens consist of the data available in the main status menu.
SET POINTS — used to edit all factory preset default set points and assign set point sources.
DIAGNOSTICS — used to review active and historical lists of diagnostic conditions. A total of 41 different diagnostics can be read at the Human Interface Panel. The last 20 diagnostics can be held in an active history buffer log at the Human Interface Panel.
SETUP — Control parameters, sensor selections, set point source selections, output definitions, and numerous other points can be edited from this menu. All points have factory preset values so
unnecessary editing is kept to a minimum.
CONFIGURATION — Preset with the proper configuration for the unit as it ships from the factory, this information would be edited only if certain features were physically added or deleted from the unit. For example, if a field supplied Trane Communication Interface (TCI) module was added to the unit in the field, the unit configuration would need to be edited to reflect that feature.
SERVICE — used to selectively control outputs (for compressors, fans, etc.) when servicing or troubleshooting the unit.This menu is accessible only at the
STOP,AUTO — when the chiller is in the stop mode, pressing the AUTO KEY will cause the UCM to go into either the Auto/Local or Auto/ICS mode, depending on the set point source setting.

Chiller Freeze Protection — The microprocessor will prevent the evaporator fluid from freezing by reducing chiller capacity, ultimately shutting down all compressors and sending a manually
Evaporator Solution Flow Interlock — The IntelliPak control requires an external evaporator flow switch interlock. An external field installed flow switch must be wired into the unit terminal strip.When an open condition is detected for six (6) seconds or longer, the compressors will shut down and after five (5) minutes an automatic resettable diagnostic alarm will be sent.
