RUN CONDITIONS: THE HOT WATER SYSTEM SHALL BE ENABLED WHEN OUTDOOR AIR TEMPERATURE IS LESS THAN 60°F (ADJ) AND AVERAGE ZONE LOAD IS GREATER THAN 10%. FOR FREEZE PROTECTION THE HOT WATER SYSTEM SHALL REMAIN ENABLED WHEN OUTDOOR AIR TEMPERATURE IS LESS THAN 35°F (ADJ). WHEN ENABLED THE HOT WATER SYSTEM SHALL RUN FOR A MINIMUM OF 20

MINUTES (ADJ).

BOILER CONTROL: THE BOILERS ARE SUBJECT TO THEIR HARDWIRED SAFETIES. WHEN THE SYSTEM IS ENABLED THE LEAD BOILER AND LEAD HOT WATER LOOP PUMP SHALL RUN. THE BOILERS SHALL BE CONFIGURED BY AN LOCHINVAR FACTORY QUALIFIED TECHNICIAN TO RUN IN CASCADE MODE. THE ROTATION AND STAGING OF THE BOILERS SHALL BE CONTROLLED BY THE CASCADE SEQUENCE INTEGRAL TO THE BOILERS. A NETWORK CONNECTION BETWEEN THE BOILERS SHALL BE PROVIDED AND WIRED BY TCC.

HOT WATER LOOP PUMPS: WHEN THE SYSTEM IS ENABLED, A SINGLE HOT WATER PUMP SHALL RUN. THE PUMP SPEED SHALL BE CONTROLLED TO MAINTAIN A SYSTEM DIFFERENTIAL OF 15 PSI (ADJ). THE PUMPS SHALL ROTATE ON ONE OF THE FOLLOWING SELECTABLE CONDITIONS, MANUALLY THROUGH SOFTWARE SWITCH, ON RUNTIME, DAILY, WEEKLY, OR MONTHLY. IF A PUMP IS COMMANDED ON, AND NO STATUS IS DETECTED, A PUMP FAILURE ALARM SHALL BE SENT. IF A PUMP HAS AN ON STATUS, AND IS NOT

COMMANDED ON, A PUMP IN HAND ALARM SHALL BE SENT.

HOT WATER SUPPLY TEMPERATURE CONTROL: THE HOT WATER SUPPLY TEMPERATURE SET POINT SHALL BE RESET TO OUTDOOR AIR TEMPERATURE BY THE BMS. EEEA HWS TEMPERATURE WELL SENSOR IS PROVIDED WITH THE BOILERS AND SHALL BE WIRED BY

TCC, MOUNTED BY OTHERS.

IF HOT WATER TEMPERATURE IS GREATER THAN 10°F (ADJ) BELOW SET POINT FOR MORE THAN 20 MINUTES (ADJ), A HOT WATER

SYSTEM TEMPERATURE FAIL ALARM SHALL BE SENT TO THE BMS.

THE NEW CONTROLS SHALL COMMUNICATE SEAMLESSLY WITH THE EXISTING ALERTON BUILDING MANAGEMENT SYSTEM
