About this file
This document is an as-built set of control drawing documents for a mechanical and control systems upgrade project at Naval Station Everett, Washington, specifically focusing on Building 1950. The project, completed by NCS Corporation for Doyon Logistics Services in October 2014, involved an industrial controls systems upgrade with a comprehensive retrofit of HVAC, heating water, and chilled water systems.
The documentation details extensive control system modifications including multiple air handling units (AHU-1, AHU-2, AHU-3, AHU-4), variable air volume (VAV) terminal units, exhaust fans, unit heaters, and hydronic systems. Key components include Distech Controls ECB series controllers, BACnet networking, variable frequency drives (VFDs), temperature and occupancy sensors, and integration of existing equipment. The project appears focused on improving energy efficiency, system monitoring, and environmental control across different building zones such as the gymnasium, kitchen, mechanical rooms, natatorium, and various administrative spaces, with precise wiring and control logic documented for each system.

POOL HEATING WATER SYSTEM
GENERAL DESCRIPTION:
HEATING WATER SYSTEM CONSISTS OF HEATING WATER CIRCULATION PUMPS SCP-1 AND
SCP-2, BOILERS B-1 AND B-2, AND BOILER SYSTEM CONTROL PANEL. HEATING WATER
SYSTEM IS INTERLOCKED THROUGH SOFTWARE TO OPERATE IN CONJUNCTION WITH AIR
HANDLING UNITS (POOL PACK AHU-1N) SCHEDULED NIGHT, WARM-UP, AND DAY MODES.
INDIVIDUAL BOILER CONTROL IS FROM INTEGRAL CONTROLS WITHIN EACH BOILER AND
ON / OFF STAGING OF BOILERS IS FROM DDCP-07 CONTROL PANEL. SCPS ARE TO RUN A
MINIMUM OF 10 MIN AFTER LAST BOILER IS SHUT-OFF. REFER TO OPERATING INSTRUCTIONS
FURNISHED WITH HEATING WATER SYSTEM CONTROL PANEL FOR COMPLETE SEQUENCE
OF OPERATION DESCRIPTION OF BOILERS AND PANEL.
UNOCCUPIED:
LEAD PUMP IS OFF AND BOILERS ARE DE-ACTIVATED. WHEN ANY FAN TERMINAL UNIT ZONE
(FT) OR AIR HANDLING UNIT (AHU-3, AHU-4) REQUIRES HOT WATER HEATING TO MAINTAIN
NIGHT UNOCCUPIED TEMPERATURE SETPOINT, HEATING WATER SYSTEM IS ACTIVATED.
ONCE ACTIVATED, HEATING WATER SYSTEM OPERATES FOR A MINIMUM 15 MINUTES OR
UNTIL DEMAND FOR HOT WATER HEATING NO LONGER EXISTS.
SCP-1 AND SCP-2 SPEEDS ARE CONTROLLING TO A HOT WATER DIFFERENTIAL PRESSURE
SETPOINT OF 10 PSI
WARM-UP:
LEAD PUMP OPERATES CONTINUOUSLY AND SYSTEM PANEL CONTROL OF BOILERS IS
ACTIVATED WHEN OUTDOOR AIR TEMPERATURE IS BELOW 66F. LEAD PUMP IS OFF AND
SYSTEM PANEL CONTROL OF BOILERS IS DEACTIVATED WHEN OUTDOOR AIR TEMPERATURE
IS ABOVE 68F.
OCCUPIED:
LEAD PUMP OPERATES CONTINUOUSLY AND SYSTEM PANEL CONTROL OF BOILERS IS
ACTIVATED WHEN OUTDOOR AIR TEMPERATURE IS BELOW 66F. LEAD PUMP IS OFF AND
SYSTEM PANEL CONTROL OF BOILERS IS DEACTIVATED WHEN OUTDOOR AIR TEMPERATURE
IS ABOVE 68F.
CIRCULATING PUMPS:
HEATING WATER SYSTEM CIRCULATING PUMPS OPERATE IN A LEAD STANDBY WITH
ALTERNATION CONFIGURATION. LEAD PUMP SELECTION IS AUTOMATICALLY ALTERNATED
BETWEEN PUMPS TO EQUAL OUT RUNTIME. ALTERNATION OCCURS WEEKLY. IN THE EVENT
OF A LEAD PUMP FAILURE – THE STANDBY PUMP IS STARTED. CURRENT SENSING SWITCH,
ON EACH CIRCULATON PUMP, INDICATES RESPECTIVE PUMPS OPERATION. CIRCULATING
PUMPS ARE PROGRAMMED WITH MINIMUM ON AND OFF TIMES TO PREVENT SHORT CYCLING.
SYSTEM PANEL CONTROL OF BOILERS:
HEATING WATER SYSTEM CONTROL PANEL PROVIDES ON / OFF STAGING OF BOILERS IN
SEQUENCE TO MAINTAIN BOILER LOAD. BOILER LOAD IS DETERMINED BY BUILDINGS
CONTROLLERS BASED ON THE CALL FOR HEAT FROM THE AHU-1N. HEATING WATER
SETPOINTS ARE INTERANL TO BOILERS AND ARE RESET BASED ON A 0-10VDC SIGNAL
HOT WATER SUPPLY TEMPERATURE SETPOINT IS RESET FROM OUTSIDE AIR TEMPERATURE
IN ACCORDANCE WITH THE FOLLOWING RESET SCHEDULE. (VALUES ARE ADJUSTABLE)
- OUTSIDE AIR TEMPERATURE = 20F TO 65F
- HOT WATER SUPPLY SETPOINT = 190F to 140F
