SYSTEM IS DISABLED. ONCE DISABLED THE BOILER WI LL BE DISABLED FIRST AND AFTER

A 5 MINUTE DELAY THE PUMP WILL BE STOPPED.

2. THE BOILER SHALL MAINTAIN BUILDING HOT WATER SUPPLY TEMPERATURE SETPOINT

BASED ON ITS INTERNAL CONTROLS. THE CONTRACTOR SHALL PROVI DE A REMOTE TEMP.

SENSOR TO BE INSTALLED IN THE SUPPLY HOT WATER PIPING. THE SETPOINT IS

DETERMINED BY THE HOT WATER RESET SCHEDULE.

3. VFD SHALL MODULATE THE HW PUMP TO MAINTAIN THE HOT WATER FLOW.

BOILER'S INTERNAL CONTROLS SHALL CONTROL BOILER CIRCULATING PUMP

OPERATION TO MAINTAIN MINIMUM FLOW TO BOILER.

4) NIGHT SETBACK - WHILE IN UNOCCUPIED MODE, THE HOT WATER SYSTEM SHALL BE

INCREASE TO 5°F ABOVE LOW LIMIT SETPOINT, SYSTEM SHALL BE DISABLED.

CHILLED WATER SYSTEM SEQUENCE OF OPERATION

1. THE CHILLED WATER SYSTEM WILL BE ENABLED WHENEVER THE SCHEDULE IS IN THE

OCCUPIED MODE AND THE OUTSIDE AIR TEMPERATURE IS ABOVE 65°F (ADJ). THE SYSTEM

WILL BE DISABLED WHENEVER THE OUTSIDE AIR TEMPERATURE IS 3°F BELOW THE CHILLED

WATER SYSTEM ENABLE SETPOINT. ONCE THE SYSTEM IS ENABLED, THE CHILLED WATER

PUMP IS STARTED. AFTER THE CHILLED WATER PUMP CURRENT SENSING RELAY VERIFIES

PUMP , THE CHILLER WILL BE ENABLED. THE CHILLER MAINTAINS BUILDING CHILLED

3) THE HOT WATER VALVE AND THE CHILLED WATER VALVE ARE PLACED IN AUTOMATIC CONTROL.

SUPPLY FAN CONTROL

I

WHEN THE SUPPLY FAN STARTER IS IN THE AUTO POSITION, THE FAN SHALL STOP WHEN THE DOC IS IN THE UNOCCUPIED MODE AND SHALL START WHEN IT IS IN THE OCCUPIED OR NIGHT LOW LIMIT MODES.

WHILE THE SUPPLY FAN IS OFF, AS DETERMINED BY THE SUPPLY FAN STATUS, THE COOLING COIL VALVE AN D THE OUTSIDE AIR DAM PER ARE CLOSED. THE RETURN AIR DAMPER IS OPEN. THE HEATING COIL VALVE IS MODULATED UNDER THE HOT DECK TEMPERATURE CONTROLLER. ZONE DAM PERS SHALL BE UNDER

THE CONTROL OF THEIR ZONE SENSORS.

WHEN THE DOC RECEIVES AN INPUT PROVING THAT THE SUPPLY FAN IS ON, THE CONTROL DAMPERS ARE POSITIONED FOR FULL RECIRCULATION OF AIR. POSITIONED TO INTRODUCE MINIMUM OUTSIDE AIR, OR MODULATED TO MAINTAIN MIXED AIR TEMPERATURE. THE CHILLED AN D HOT WATER VALVES SHALL BE MODULATED UNDER AUTOMATIC CONTROL TO MAINTAIN HOT DECK AND COLD DECK SETPOINTS.ZONE DAMPERS SHALL BE UNDER

THE CONTROL OF THEIR ZONE SENSORS.

THE VFD SHALL MODULATE THE FAN'S SPEED BASED ON DIFF. PRESSURE SENSOR LOCATED IN THE SUPPLY AIR DUCT TO MAINTAIN THE AIR FLOW REQUIRED. THE VFD SHALL BE CONFIGURED SO AS TO PREVENT THE FAN FROM

OPERATING OUTSIDE OF THE MANUFACTURER'S RECOMMENDATED LI MITS.

SAFETIES

1) FREEZE PROTECTION: WHEN THE MIXED AIR TEMPERATURE FALLS BELOW THE SETPOINT OF 38°F (ADJ .) A SET OF NORMALLY CLOSED FREEZE STAT CONTACTS IN THE AHU FAN STARTER SAFETY CIRCUIT WILL OPEN, PREVENTING THE AHU FAN FROM OPERATING. AN ADDITIONAL SET OF NORMALLY OPEN CONTACTS IN THE FREEZE STAT SHALL CLOSE PROVIDING AN ALARM TO THE DOC. A MANUAL RESET AT THE FREEZE STAT IS REQUIRED

TO RESTART THE FAN AND CLEAR THE ALARM.

THE AHU FAN FROM OPERATING. THE DOC SYSTEM SHALL ALSO SEND AN ALARM SIGNAL TO THE FIRE ALARM SYSTEM

IN THE BUILDING.

INDOOR AIR QUALITY (IAQ):

CONTRACTOR SHALL INSTALL A CARBON DIOXISE SENSOR IN THE OUTSIDE AIR TO ESTABLISH THE BASELINE C02 LEVEL FOR THE IAQ ALERT. CONTRACTOR SHALL ALSO INSTALL C02 SENSORS AND SHALL PLACE ONE IN THE KITCKEN AREA, ONE IN THE DINNING AREA AND ONE IN THE SALES AREA. WHENEVER THE C02 LEVEL IN THE SPACES EXC EEDS THE BASELINE BY 400 PPM AN ALARM SHALL BE INITIATED. THE ALARM SHALL INDICATE WHICH OF THE C02 SENSORS

INDICATED THE ALARM.

NIGHT SETBACK

WHILE IN UNOCCUPIED MODE, IF ANY SPACE SENSOR FALLS BELOW 60 °F(ADJ .) OR ABOVE 90 °F(ADJ.) THE AHU SHALL BE ENABLE. THE AHU SHALL PLACED IN AUTOMATIC CONTROL UNTIL THE SPACE SENSOR REACHES 65°F OR 85°F

RESPECTIVELY.
