780 CMR 1301.8.4
I. THE IDEAS, CONCEPTS AND CRITERIA DESCRIBED BY THE OWNER TO BE
IMPORTANT FOR THE TYPE OF HVAC SYSTEMS BEING INSTALLED
INCLUDED, COMFORT, HIGH EFFICIENCY, LOW OPERATING COST, AND
MULTIPLE ZONE CONT30L.
2. BASIS FOR THE DESIGN:
A. ACCOMPLISH THE OWNER'S IDEAS, CONCEPTS AND SYSTEM CRITERIA.
B. SYSTEMS WERE DESIGNED IN ACCORDANCE WITH PROVEN ENGINEERING
PRACTICE, ARI, SMACNA, ASHRAE, AND MANUFACTURER'S LISTING
REQUIREMENTS AND THE REQUIREMENTS OF 780 CMR AND ALL
REFERENCED STANDARDS (780 CMR 101.6)
J. SEQUENCE OF OPERATION:
A. HYDRONIC HEATING
THE HYDRONIC HEATING SYSTEM PROVIDES TWO MAIN FUNCTIONS.
ITS PRIMARY FUNCTION PROVIDES HOT WATER TO HYDRONIC COILS
LOCATED IN EACH OF THE AIR HANDLING UNITS. HOT WATER IS
CIRCULATED TO EA.H OF THE HW COILS AT A WATER TEMPERATURE
WHICH IS ADJUSTED BASED UPON AN ALGORITHM INCLUDING
CURRENT SYSTEM DEMAND AND OUTSIDE AIR TEMPERATURE. ANY
ZONE THERMOSTAT HAS THE CAPABILITY OF CALLING FOR HEAT
WHEN OTHER ZONES ARE SATISFIED.
A SECONDARY BOILER FUNCTION PROVIDES LOW TEMPERATURE
WATER TO THE FLOOR WARMING RADIANT SYSTEM. THIS SYSTEM'S
FUNCTION IS NOT CONTROLLED BY THE SPACE THERMOSTATS
(EXCEPT FOR THE BASEMENT) BUT IS ADJUSTED TO MAINTAIN A
"WARM FLOOR", IN REASING THE OCCUPANT COMFORT LEVEL AT A
LOWER HEATING SPACE TEMPERATURE.
C. DIRECT EXPANSION COOLING
THREE INDEPENDENT AIR CONDITIONING SYSTEMS HAVE BEEN
PROVIDED. EACH SYSTEM CONSIST OF A COMMUNICATING VARIABLE
SPEED FAN COIL UNIT WITH DIRECT EXPANSION COOLING COIL, AN
ELECTRONIC AIR CLEANER, AND A 17 SEER TWO STAGE CONDENSING
UNIT.
CONTROLS FO? EACH SYSTEM ARE MANAGED BY A MASTER CONTROL
WHICH ELECTRONICALLY COMMUNICATES WITH THE SYSTEMS VARIOUS
COMPONENTS; INTERPRETING SYSTEM AIR STATIC PRESSURE, FAN
COIL STATUS, ZONE DAMPER STATUS, CONDENSING UNIT STATUS,
INDOOR TEMPERATURE AND HUMIDITY STATUS, AND OUTDOOR AIR
TEMPERATURE. INFORMATION RECEIVED BY THE MASTER CONTROL, IS
PROCESSED BY THIS DEVICE AND SENDS APPROPRIATE SIGNALS TO
THE VARIOUS SY3 M COMPONENTS AS NECESSARY TO SATISFY THE
USER SETPOiNTS.
4. THE TYPE, SIZE AND CAPACITY OF THE SYSTEM COMPONENTS ARE
NOTED ON THESES D°AWINGS.
5. FINAL ACCEPTANCE OF THE HVAC SYSTEMS' WILL BE BASED UPON
THE ENGINEER'S INS.r=10N WHICH SHALL INCLUDE THE FOLLOWING:
A. COMPLETED PJNC-I LIST ITEMS.
B. REVIEW AND ADP::OVAL OF CONTRACTOR'S BALANCING TEST.
C. SPOT CHECK FO? THE ACCURACY OF BALANCING REPORT.
VERIFICATION G.= SYSTEM OPERATION IN ACCORDANCE WITH THE
DESIGN DOCU!,/E I:S.
D. FINAL AFFIDAVIT TJ BUILDING DEPARTMENT
6. THE HVAC CONTRACTOR? SHALL SUBMIT THE FOLLOWING TO THE
ENGINEER FOR AF,�?OIAL:
A. HVAC EQUIPMENT AND CONTROL PRODUCT DATA SHEETS.
B. BALANCING P, PO.=T.
C. OPERATING AND MAINTENANCE MANUALS INCLUDING, PRODUCT DATA
SHEETS, AS—BJILT DRAWINGS AND THE RECOMMENDED WEEKLY,
MONTHLY AND "EARLY PREVENTATIVE MAINTENANCE PROCEDURES
7. THE HVAC CONTPP4.CTO° SHALL MAINTAIN A SET OF RECORD
DRAWINGS (AS—BU,2TS) WI-L'CH SHALL BE SUBMITTED TO THE
ENGINEER (SEE 6 ABOVE) AS A PREREQUISITE OF FINAL
ACCEPTANCE, PER Cl.,q 780 116.0.
