RTU-1 AND RTU-2 CONTROLS SCHEMATIC - RF DX GAS

RTU-1 AND RTU-2 - ON-OFF CONTROL WITH SUPPLY AIR ISOLATION DAMPER

GENERAL REQUIREMENTS

THE RTUS SHALL BE CONTROLLED BY THEIR OWN PACKAGED CONTROL SYSTEM. THE UNITS ARE

MANUFACTURED BY TRANE, MODEL INTELLIPAK II SXHJ13040A0162LA5J55K1000B00C0000F01A0.

THE BAS MONITORS AND COMMUNICATES BUILDING INFORMATION AND SETPOINTS TO THE

PACKAGED CONTROL SYSTEMS OF RTU-1 AND RTU-2.

RTU-1 AND RTU-2 CAN SUPPLY CONDITIONED AIR TO THE SPACE INDIVIDUALLY OR TOGETHER AS A

DUPLEX SYSTEM. BOTH AHUS ARE CONNECTED BY A COMMON SUPPLY AIR DUCT HEADER. EACH

RTU HAS A SEPARATE WILD RETURN AIR DUCT FROM THE WAREHOUSE AREA.

EACH RTU IS SERVED BY A SUPPLY AIR ISOLATION DAMPER. THE SUPPLY AIR RTU ISOLATION

DAMPER IS OPENED-CLOSED BY THE BAS DDC PANEL.

TO START THE RTU, FIRST THE BAS OPENS THE APPROPRIATE RTU ISOLATION DAMPER. THE

DAMPER END SWITCH STATUS INDICATES TO THE BAS DDC PANEL THAT THE DAMPER IS OPEN AND

THE BAS SYSTEM COMMANDS THE RTU TO START.

WHEN AN RTU IS ONLINE AND IS UNABLE TO MAINTAIN SPACE SETPOINT TEMPERATURE FOR A

PERIOD OF 30 MINUTES (ADJ.), THE LEAD RTU IS STOPPED, BOTH RTU ISOLATION DAMPERS ARE

PROVEN OPENED AND THEN BOTH RTUS ARE COMMANDED ON BY THE BAS SYSTEM. THEY SHALL

RAMP UP THEIR FANS IN UNISON TO MEET SUPPLY DUCT STATIC PRESSURE SETPOINT.

WHEN AN RTU FAILS, SUCH THAT THE RTU IS SHUTDOWN, ITS ISOLATION DAMPER IS CLOSED BY THE BAS AND THE LAG RTU IS STARTED UP PER THE SEQUENCE DESCRIBED ABOVE OR CONTINUES

TO RUN AND AN ALARM IS ISSUED TO THE BAS SYSTEM.

RUN CONDITIONS - SCHEDULED:

THE UNIT SHALL RUN BASED UPON AN OPERATOR ADJUSTABLE SCHEDULE.

RTU RUNTIME:

THE BAS SHALL MONITOR AND LOG RTU RUNTIME. IMPORT RUNTIME FROM EXISTING CONTROLS

SYSTEM.

LEAD AHU WILL SWAP EACH WEEK. IF THE CURRENT LEAD AHU SUPPLY FAN RUNTIME EXCEEDS

THAT OF THE LAG AHU, IT WILL MAINTAIN LEAD STATUS.

HIGH STATIC SHUTDOWN:

THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING A HIGH STATIC

SHUTDOWN SIGNAL. HIGH STATIC SHUTDOWN SHALL BE SET AT 3 IN WC (ADJ).

SUPPLY AND RETURN AIR SMOKE DETECTION:

THE UNIT SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING A SUPPLY AIR OR

RETURN AIR SMOKE DETECTOR STATUS.

AHU OPTIMAL START:

THE UNIT SHALL START PRIOR TO SCHEDULED OCCUPANCY BASED ON THE TIME NECESSARY FOR

THE ZONES TO REACH THEIR OCCUPIED SETPOINTS. THE START TIME SHALL AUTOMATICALLY

ADJUST BASED ON CHANGES IN OUTSIDE AIR TEMPERATURE AND ZONE TEMPERATURES.

SUPPLY FAN:

THE PACKAGED UNIT CONTROLLER SHALL CONTROL THE SUPPLY FAN. THE PACKAGED UNIT

CONTROLLER SHALL COMMUNICATE SUPPLY FAN STATUS WITH THE BAS.

SUPPLY AIR DUCT STATIC PRESSURE CONTROL:

THE BAS SHALL MEASURE DUCT STATIC PRESSURE AT THE END OF EACH BRANCH MAIN. THE BAS

SHALL REPORT THE LOWEST DUCT STATIC PRESSURE TO THE RTU. THE UNIT PACKAGED

CONTROLLER SHALL MODULATE THE SUPPLY FAN SPEED TO MAINTAIN A DUCT STATIC PRESSURE SETPOINT. THE STATIC PRESSURE SETPOINT SHALL BE RESET BASED UPON THE POSITION OF THE ZONE DAMPERS, WITH A GOAL OF REDUCING THE STATIC PRESSURE UNTIL AT LEAST ONE ZONE

DAMPER IS NEARLY WIDE OPEN.

• THE INITIAL DUCT STATIC PRESSURE SETPOINT SHALL BE 1.5 IN H2O (ADJ.).

• IF NO ZONE DAMPER IS NEARLY WIDE OPEN, THE SETPOINT SHALL INCREMENTALLY RESET

DOWN TO A MINIMUM OF 1.3 IN H2O (ADJ.) .

• AS ONE OR MORE DAMPERS NEARS THE WIDE OPEN POSITION, THE SETPOINT SHALL

INCREMENTALLY RESET UP TO A MAXIMUM OF 1.8 IN H2O (ADJ.).

THE BAS SHALL ALSO COMMUNICATE WITH RTU-1 AND RTU-2 TO DETERMINE IF THE COOLING

COMPRESSORS ARE ON. IF THE COMPRESSORS ARE ON, THE STATIC PRESSURE SETPOINT SHALL

BE SET AT 2.5 IN H20 (ADJ.) UNTIL THE COMPRESSORS ARE TURNED OFF.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• HIGH SUPPLY AIR STATIC PRESSURE: IF THE SUPPLY AIR STATIC PRESSURE IS 25% (ADJ.)

GREATER THAN SETPOINT.

• LOW SUPPLY AIR STATIC PRESSURE: IF THE SUPPLY AIR STATIC PRESSURE IS 25% (ADJ.)

LESS THAN SETPOINT.

SUPPLY AIR TEMPERATURE SETPOINT - OPTIMIZED:

THE BAS SHALL SHALL MONITOR THE SUPPLY AIR TEMPERATURE AND SHALL MAINTAIN A SUPPLY

AIR TEMPERATURE SETPOINT RESET BASED ON ZONE COOLING REQUIREMENTS. THE BAS SHALL

COMMUNICATE THE SETPOINT WITH THE PACKAGED UNIT CONTROLLER.

THE SUPPLY AIR TEMPERATURE SETPOINT SHALL BE RESET FOR COOLING BASED ON ZONE

COOLING REQUIREMENTS AS FOLLOWS:

• THE INITIAL SUPPLY AIR TEMPERATURE SETPOINT SHALL BE 55°F (ADJ.).

• AS COOLING DEMAND INCREASES, THE SETPOINT SHALL INCREMENTALLY RESET DOWN TO

A MINIMUM OF 53°F (ADJ.).

• AS COOLING DEMAND DECREASES, THE SETPOINT SHALL INCREMENTALLY RESET UP TO A

MAXIMUM OF 62°F (ADJ.) .

DEHUMIDIFICATION:

THE BAS CONTROLLER SHALL MEASURE THE SPACE HUMIDITY AND PLACE THE RTU INTO

DEHUMIDIFICATION MODE AS FOLLOWS.

• WHEN THE ZONE HUMIDITY IS GREATER THAN 60% (ADJ) RH, THE BAS SHALL

INCREMENTALLY RESET THE SUPPLY AIR TEMPERATURE SETPOINT DOWN TO A MINIMUM

TEMPERATURE OF 53°F (ADJ.).

COOLING STAGES:

THE UNIT PACKAGED CONTROLLER SHALL MEASURE THE SUPPLY AIR TEMPERATURE AND STAGE

THE COOLING TO MAINTAIN ITS COOLING SETPOINT.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• HIGH SUPPLY AIR TEMP: IF THE SUPPLY AIR TEMPERATURE IS 5°F (ADJ.) GREATER THAN

SETPOINT FOR 15 MINUTES (ADJ.).

STATIC PRESSURE SENSOR AND DDC CONTROLLER SIGNAL AND LOOP OUTPUT TRANSFERRED TO

THE RTU CONTROLLER FOR CONTROL OF THE RELIEF FAN. THE SIGNAL ADJUSTS THE SET-POINT OF THE RTU CONTROLLER RELIEF AIR CONTROL LOOP. WAREHOUSE WILL CONTROL AT A POSITIVE

0.05 IN WC (ADJ.) COMPARED TO OUTSIDE AIR.

THE PACKAGED UNIT CONTROLLER SHALL COMMUNICATE RELIEF FAN STATUS WITH THE BAS.

ECONOMIZER:

THE UNIT PACKAGED CONTROLLER SHALL CONTROL ECONOMIZER MODE. THE BAS SHALL BE ABLE

TO COMMUNICATE SETPOINTS TO THE UNIT PACKAGED CONTROLLER.

RETURN AIR TEMPERATURE:

THE CONTROLLER SHALL MONITOR THE RETURN AIR TEMPERATURE.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• HIGH RETURN AIR TEMP: IF THE RETURN AIR TEMPERATURE IS GREATER THAN 90°F (ADJ.).

• LOW RETURN AIR TEMP: IF THE RETURN AIR TEMPERATURE IS LESS THAN 45°F (ADJ.).

SUPPLY AIR TEMPERATURE:

THE CONTROLLER SHALL MONITOR THE SUPPLY AIR TEMPERATURE.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• HIGH SUPPLY AIR TEMP: IF THE SUPPLY AIR TEMPERATURE IS GREATER THAN 120°F (ADJ.).

• LOW SUPPLY AIR TEMP: IF THE SUPPLY AIR TEMPERATURE IS LESS THAN 45°F (ADJ.).

THREE BOILER SYSTEM WITH CONDENSING BOILERS, PRIMARY SECONDARY FLOW.

COORDINATE CONTROLS SCOPE OF WORK WITH BOILER REPLACEMENT PROJECT UNDER A

SEPARATE CONTRACT. CONTACT OWNER FOR MORE INFORMATION.

BOILER SYSTEM RUN CONDITIONS:

THE BOILER SYSTEM SHALL BE ENABLED TO RUN WHENEVER:

• A DEFINABLE NUMBER OF HOT WATER COILS NEED HEATING.

• AND OUTSIDE AIR TEMPERATURE IS LESS THAN 65°F (ADJ.).

TO PREVENT SHORT CYCLING, THE BOILER SYSTEM SHALL RUN FOR AND BE OFF FOR MINIMUM

ADJUSTABLE TIMES (BOTH USER DEFINABLE), UNLESS SHUTDOWN ON SAFETIES OR OUTSIDE AIR

CONDITIONS.

THE BOILER SHALL RUN SUBJECT TO ITS OWN INTERNAL SAFETIES AND CONTROLS.

THE BOILER SYSTEM SHALL ALSO RUN FOR FREEZE PROTECTION WHENEVER THE OUTSIDE AIR

TEMPERATURE IS LESS THAN 38°F (ADJ.).

THE BAS SHALL MONITOR AND LOG BOILER AND PUMP RUNTIME. IMPORT RUNTIME FROM EXISTING

CONTROLS SYSTEM.

BOILER SAFETIES:

THE FOLLOWING SAFETIES SHALL BE MONITORED:

• BOILER ALARM.

• LOW WATER LEVEL.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• BOILER ALARM.

• LOW WATER LEVEL ALARM.

HOT WATER PUMP LEAD/LAG OPERATION:

THE TWO HOT WATER PUMPS SHALL OPERATE IN A LEAD/LAG FASHION.

• THE LEAD PUMP SHALL RUN FIRST.

• ON FAILURE OF THE LEAD PUMP, THE LAG PUMP SHALL RUN AND THE LEAD PUMP SHALL

TURN OFF.

• ON DECREASING HOT WATER DIFFERENTIAL PRESSURE, THE LAG PUMP SHALL STAGE ON

AND RUN IN UNISON WITH THE LEAD PUMP TO MAINTAIN HOT WATER DIFFERENTIAL

PRESSURE SETPOINT.

THE DESIGNATED LEAD PUMP SHALL ROTATE UPON ONE OF THE FOLLOWING CONDITIONS (USER

SELECTABLE):

• MANUALLY THROUGH A SOFTWARE SWITCH

• IF PUMP RUNTIME (ADJ.) IS EXCEEDED

• DAILY

• WEEKLY

• MONTHLY

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• HOT WATER PUMP

• FAILURE: COMMANDED ON, BUT THE STATUS IS OFF.

• RUNNING IN HAND: COMMANDED OFF, BUT THE STATUS IS ON.

• RUNTIME EXCEEDED: STATUS RUNTIME EXCEEDS A USER DEFINABLE LIMIT.

• VFD FAULT.

HOT WATER DIFFERENTIAL PRESSURE CONTROL:

THE CONTROLLER SHALL MEASURE HOT WATER DIFFERENTIAL PRESSURE AND MODULATE THE

HOT WATER PUMP VFDS IN SEQUENCE TO MAINTAIN ITS HOT WATER DIFFERENTIAL PRESSURE

SETPOINT.

THE FOLLOWING SETPOINTS ARE RECOMMENDED VALUES. ALL SETPOINTS SHALL BE FIELD

ADJUSTED DURING THE COMMISSIONING PERIOD TO MEET THE REQUIREMENTS OF ACTUAL FIELD

CONDITIONS.

THE CONTROLLER SHALL MODULATE HOT WATER PUMP SPEEDS TO MAINTAIN A HOT WATER

DIFFERENTIAL PRESSURE OF 12 PSI (ADJ.).
