Engineering Guide Specifications
CoolLogic Control System
Remote CoolLogic Control system shall be fully compatible
with the Building Automation System via native BACnet
and L on W orks communication protocols . Scheduling
of the various compressors shall be performed by the
master microprocessor based controller . A compressor
run time equalization sequence is provided to ensure even
distribution of compressor run time . A load limit control
shall be available to limit the number of compressors that
can be energized at one time .
The CoolLogic Control System shall monitor and report the
following for each refrigeration circuit in each module:
• Discharge pressure and temperature faults
• Suction pressure and temperature faults
• Compressor winding high temperature fault
• Low evaporator leaving chilled water temperature fault
The Master Controller shall monitor and report the following
system parameters for the chiller system:
• Chilled water entering and leaving temperature
•
Evaporator water flow availability
Any module failure condition shall cause a “fault” indication
at the Control Panel and shutdown of that compressor
circuit with the transfer of the load requirements to the
next available compressor circuit . In the case of a system
“fault” the entire chiller will be shut down . When any fault
occurs, the CoolLogic Control System shall record conditions
at the time of the fault, and store the data for recall . This
information shall be capable of recall through the keypad
of the Master Control Panel and displayed on the 4 line
by 40 character, back-lit LCD . A history of faults shall be
maintained including date and time for each fault (up to the
last 100 occurrences) . Internal leaving chilled water reset
control will insure that the parallel evaporators are operated
above the freeze point for part load operation .
Factory Testing
Each remote air cooled chiller module shall be pressure-
tested, evacuated and charged with nitrogen .
