M701 - GENERAL CRITERIA HONEYWELL CONTROLS REPLNT.pdf

GENERAL NOTES-

AUTOMATIC TEMPERATURE CONTROLS

A. A COMPLETE SYSTEM OF AUTOMATIC TEMPERATURE CONTROLS SHALL BE INSTALLED AS REQUIRED TO ACCOMPLISH THE SEQUENCE OF CONTROL FOR VARIOUS ITEMS OF EQUIPMENT AND SYSTEMS DESCRIBED HEREINAFTER. THE SYSTEM SHALL BE A DIRECT DIGITAL CONTROL SYSTEM UTILIZING ELECTRIC OR

PNEUMATIC ACTUATION AS DEFINED IN THE SPECIFICATIONS.

B. PROVIDE ALL EQUIPMENT (VALVES, DAMPERS, ACTUATORS, CONTROLLERS, ETC.) REQUIRED TO PERFORM THE FUNCTIONS SPECIFIED UNLESS NOTED HEREIN OR ELSEWHERE IN THESE CONTRACT DOCUMENTS. ELECTRIC MOTOR DRIVEN EQUIPMENT (PUMPS, CHILLERS, COMPRESSORS, COOLING TOWERS, ETC.) SHALL BE PROVIDED WITH MINIMUM ON AND OFF TIMERS TO PREVENT SHORT CYCLING OF THE EQUIPMENT (COORDINATE WITH

EQUIPMENT MANUFACTURER'S).

C. THE CONTROL DIAGRAMS AND INFORMATION CONTAINED WITHIN ARE TO SHOW DESIGN INTENT. IT IS THE CONTROL SYSTEM SUPPLIER’S RESPONSIBILITY TO DEVELOP DETAILED AND COMPLETE CONTROL DIAGRAMS

AND SHOP DRAWINGS TO ACCOMPLISH THE SPECIFIED SEQUENCES.

D. POINTS LIST ARE SHOWN AS AIDS TO THE CONTRACTOR INDICATING THE MINIMUM POINTS REQUIRED FOR CONTROL, AND MONITORING. ALL INPUT AND OUTPUT POINTS, AND THEIR REQUIRED INTERFACE AND ACCESSORY HARDWARE, SHALL BE PROVIDED FOR A COMPLETE AND FUNCTIONAL CONTROL SYSTEM. IF OR WHEN ADDITIONAL POINTS ARE REQUIRED TO ACCOMPLISH THE SEQUENCES OF CONTROL SPECIFIED, THESE POINTS, ALONG WITH ADDITIONAL DIRECT DIGITAL CONTROL PANEL(S) (IF REQUIRED), SHALL ALSO BE

PROVIDED.

E. PROVIDE ALL BULB WELLS FOR TEMPERATURE SENSING. PIPING WORK SHALL INCLUDE PROPERLY SIZED

WELDOLET OR THREADOLET FITTINGS.

F. PROVIDE ALL ELECTRICAL WORK REQUIRED. THIS SHALL INCLUDE BUT NOT BE LIMITED TO WIRING, CONDUIT, TRANSFORMERS, RELAYS AND FUSES.

G. THE FOLLOWING CONTROL SEQUENCES HAVE BEEN WRITTEN TO COMMUNICATE THE DESIGN INTENT REGARDING EQUIPMENT CONTROL. DESIGN INTENT FOCUSES ON THE SEQUENCE OF DEVICES (E.G., TO UTILIZE ECONOMIZER BEFORE MECHANICAL COOLING), CONTROLLING INPUTS (E.G., TO CONTROL THE COOLING COIL TO THE SUPPLY AIR TEMPERATURE), AND DESIRED RESULT (E.G., TO MAINTAIN SUPPLY AIR TEMPERATURE AT

THE EFFECTIVE SETPOINT).

H. CONTROL SEQUENCES SHOULD BE REGARDED AS PERFORMANCE BASED, WITH STRICT ADHERENCE TO THE SPECIFIED LANGUAGE NOT ALWAYS REQUIRED. MANY COMBINATIONS OF LOGIC CAN RESULT IN THE DESIRED CONTROL. ALTERNATE LOGIC THAT RESULTS IN THE SAME PERFORMANCE AND ENERGY USAGE AS SPECIFIED IS CONSIDERED ACCEPTABLE. ALTERNATE LOGIC CREATING SIMULTANEOUS HEATING/COOLING OR UNSTABLE

CONTROL IS NOT ACCEPTABLE.

I. GENERAL DESIGN SEQUENCE STRUCTURE:

• “MODES” WHERE SPECIFIED ARE USED TO SIGNAL MAJOR CHANGES TO EQUIPMENT OPERATED (E.G.

OCCUPIED/UNOCCUPIED/OPTIMAL START, HEATING/COOLING, ETC.).

• “RESETS” WHERE SPECIFIED ARE USED TO CHANGE A SETPOINT VALUE DYNAMICALLY. RESETS SHOULD

ALWAYS BE BOUND BY THE MINIMUM AND MAXIMUM VALUES. SIMPLE LINEAR/PROPORTIONAL BASED RESETS ARE ONLY ALLOWED WHERE SPECIFIED, OTHERWISE A FEEDBACK-BASED ALGORITHM IS REQUIRED

(E.G., PID OR "TRIM AND RESPOND")

• “LOOPS” WHERE SPECIFIED ARE USED TO INDICATE USE OF PID ALGORITHMS TO HOLD AN INPUT SIGNAL AT A SPECIFIED SETPOINT WITHOUT SIGNIFICANT LONG-TERM DEVIATION FROM SETPOINT. SIMPLE ERROR-

BASED OR PROPORTIONAL ONLY CONTROL IS NOT ACCEPTABLE.

• “SEQUENCING” WHERE SPECIFIED IS USED TO CONTROL THE ORDER OF COMPONENTS ENGAGED TO SATISFY A CERTAIN CONDITION. FOR INSTANCE, A HEATING COIL, ECONOMIZER, AND COOLING COIL ALL AFFECT THE SUPPLY AIR TEMPERATURE, SO THEY MUST BE SEQUENCED TO ELIMINATE SIMULTANEOUS

HEATING AND COOLING. GRAPHICAL REPRESENTATION OF LOOPS AND SEQUENCING HAVE BEEN

SOMETIMES INCLUDED FOR CLARITY.

J. ANY LOGIC DEPENDENT ON NETWORK INFORMATION SHALL HAVE PROVISIONS TO FALLBACK TO A SAFE STATE UPON LOSS OF NETWORK CONNECTION (I.E., OCCUPIED MODE IN THE CASE OF AN OCCUPANCY COMMAND).

K. ALL SETPOINTS, TIMERS, DEADBANDS, PID GAINS, ETC. LISTED IN SEQUENCES SHALL BE ADJUSTABLE BY THE USER WITH APPROPRIATE ACCESS LEVEL WHETHER INDICATED AS ADJUSTABLE IN SEQUENCES OR NOT.

SOFTWARE POINTS SHALL BE USED FOR THESE VARIABLES. FIXED SCALAR NUMBERS SHALL NOT BE

EMBEDDED IN PROGRAMS EXCEPT FOR PHYSICAL CONSTANTS AND CONVERSION FACTORS.

L. ALL DDC SYSTEM CONTROL POINTS SHALL HAVE A DEFAULT VALUE IN CASE OF SENSOR FAILURE OR LOGIC ERROR. ALL CONTROLLED DEVICES SHALL FAIL SAFE ON LOSS OF CONTROL. ALL SETPOINTS AND PARAMETERS

SHALL BE FULLY ADJUSTABLE FROM THE END USER / OWNER INTERFACE.

M. OVERRIDES SHALL BE PROVIDED FOR SYSTEM TESTING AND COMMISSIONING FROM THE USER INTERFACE.

N. ANALOG OUTPUTS SHOULD BE CONTROLLED BASED UPON THE LOOPS AND SEQUENCING AS SPECIFIED.

REQUIRED LOGIC TO ENSURE OUTPUTS ACT UPON SAFETIES, MODES, OR OTHER INTERLOCKING LOGIC IS THE RESPONSIBILITY OF THE CONTROL CONTRACTOR. EFFORTS TO STATE INTERLOCKING CONDITIONS HAVE BEEN MADE, BUT IT IS THE ULTIMATE RESPONSIBILITY OF THE CONTROL CONTRACTOR TO ENSURE OUTPUTS ARE

COMMANDED APPROPRIATELY DURING ALL CONDITIONS.

O. IT IS NOT THE INTENT OF THE DESIGN SEQUENCES TO SPECIFY ALL PROGRAMMING REQUIRED FOR STABLE CONTROL. TRANSITION BETWEEN MODES OR SEQUENCING OF OUTPUTS OFTEN REQUIRES DELAYS, RAMPS, RESETS, OR OTHER LOGIC ELEMENTS TO ENSURE STABLE AND SMOOTH CONTROL. IT IS THE RESPONSIBILITY OF THE CONTROLS CONTRACTOR TO TEST EQUIPMENT THOUGH ALL TRANSITIONS, ADDING PROGRAMMING AS

REQUIRED TO ENSURE STABLE PERFORMANCE.

P. IT IS THE RESPONSIBILITY OF THE CONTROL CONTRACTOR TO TUNE ALL LOOPS INITIALLY DURING START UP AND SUBSEQUENTLY THOUGH OPERATION OF THE BUILDING DURING VARIOUS WEATHER CONDITIONS. AT MINIMUM, PID TUNING SHOULD BE EVALUATED DURING START-UP AND OCCUPIED SUMMER, WINTER, AND

SHOULDER SEASONS.

Q. UNDERSTANDING THE ABOVE INFORMATION, CONTROL CONTRACTORS ARE REQUIRED TO SUBMIT SEQUENCES OF OPERATION AS THEY INTEND TO PROGRAM THEIR CONTROLLERS. SIMPLY COPYING-AND-PASTING OF THE DESIGN SEQUENCES WILL BE FLAGGED IN SUBMITTAL REVIEW AS NOT CONFORMING TO THE INTENT OF THE SUBMITTAL. THE SEQUENCE OF OPERATION INCLUDED IN THE CONTROL SUBMITTAL SHOULD DOCUMENT THE

CONTROL SEQUENCE “AS PROGRAMMED” IN A WRITTEN FORMAT FOR ENGINEER REVIEW. AFTER

CONSTRUCTION, FINALIZED SEQUENCES WITH ALL ADJUSTMENTS MADE SHALL BE DOCUMENTED IN AS-BUILTS

FOR OWNER REFERENCE.
