3. OA MD D-1 AND REL A MD D-3 SHALL CLOSE AND RA MD D-2 SHALL OPEN DURING NIGHT

CYCLE OR ANYTIME FAN STOPS.

4. CHILLED WATER COIL 3-WAY VALVE V-2A SHALL GO TO FULL BYPASS WHEN SUPPLY FAN

STOPS.

5. DIFFERENTIAL PRESSURE SWITCH DP-1 SHALL PROVIDE FAN INTERLOCK AND “FAN ON”

INDICATION AT OPERATOR WORKSTATION.

6. AVERAGE SPACE TEMPERATURE INDICATION SHALL ALSO BE PROVIDED AT OPERATOR

WORKSTATION.

7. UNIT SHALL SHUT DOWN UPON RECEIVING SIGNAL FROM FIRE ALARM CONTROL PANEL.

FOR GUIDANCE ONLY. POINTS INDICATED ARE MINIMUM NUMBER OF POINTS. TEMPERATURE CONTROL CONTRACTOR IS RESPONSIBLE FOR PROVIDING ADDITIONAL POINTS AS NEEDED TO COMPLY WITH THE SEQUENCE OF OPERATION AND THE

BOILER TO COMPLETE ITS FIRING CIRCUIT.

a. BOILER B-1 / HOT WATER SYSTEM TEMPERATURE CONTROL

1. BOILER IS CONTROLLED WITH ITS ON BOARD ORIGINAL EQUIPMENT

MANUFACTURER CONTROLLER. NEW BUILDING AUTOMATION SYSTEM

SHALL PROVIDE THE NECESSARY INTERFACE AS FOLLOWS TO ENABLE

AND DISABLE THE OPERATION OF THE EQUIPMENT AND PROVIDE ALARMS

AS SPECIFIED AT THE OPERATOR WORK STATION

2. IMMERSION SENSOR TS-1 AND OUTDOOR SENSOR TS-5 SHALL RESET THE

HWS TEMPERATURE FROM 200 DEG. F. (ADJ.) TO 160 DEG. F (ADJ.) AS

OUTDOOR TEMPERATURE RISES FROM -10 DEG. F. (ADJ.) TO 70 DEG. F.

(ADJ.) BY MODULATING 3-WAY VALVE V-13 (FAIL SAFE IN FULL HEAT

POSITION).

3. AQUASTAT IN BOILER WILL CONTROL BOILER WATER TEMPERATURE AT

200 DEG. F. (ADJ.) CONSTANT.

4. FLOW SWITCH FS-2 SHALL PREVENT BOILER OPERATION UNLESS HW

PUMP. P-1 OR P-1A ARE OPERATING AND FLOW IS PROVEN BY FS-2.

5. BOILER AND PUMPS SHALL STOP WHEN OUTDOOR TEMPERATURE RISES

ABOVE 60 DEG. F. (ADJ.), (P-1A IS STANDBY).

6. HWR SENSOR TS-2 PROVIDES TEMPERATURE INDICTION TO THE DDC

SYSTEM.

7. OUTDOOR SENSOR TS-5 ALSO PROVIDES TEMPERATURE INDICATION AT

OPERATOR WORKSTATION.

8. BAS SHALL ISSUE AN ALARM AT OPERATOR WORKSTATION WHEN HOT

WATER PUMPS P-1, P-1A ARE COMMANDED ON AND FLOW IS NOT PROVEN

BY FS-1.
