59 8/5/04 8/13/04 Why are we getting a HighStcPres Alarm on MnAC1 on start-up? Cont. 8/31/04
59 10/1/04 QA increase delay from 10 minutes to 20 minutes QA
MnAC1 and MnAC2 fans operated Saturday morning (10/30/04) for a few minutes.
No zone appeared overridden. Why? Check if zone is in setback. Setback Mode is
not trended. The lowest zone temps on MnAC1 & 2 were down to ~55 Deg.F from
7:00-8:30AM. This is above Setback Mode starting setpoint of 50 to 52 Deg.F.
117 10/3/0/04 11/2/04 Cont.: Needs to be verified by team. (7)
MnAC3 does not need to be scheduled on. The HVCR is used infrequently and staff
is used to using an on timer. Can local override provide an total of 8hrs on time per
16 4/27/04 4/28/04 use and users trained? Yes.
MnAC3: once VAVs are operational and stat is installed, stat can be programmed for
2hr increments; max time for this equipment is only 224 minutes. Program my be
16 4/28/04 forthcoming in November to change this to 8 hours. Cont., (4, 5) QA
MnAC3 chilled water valve is at 100%, while zone is calling for heating. Why? No
129 11/11/04 11/17/04 longer occuring. Cont. 11/19/04 QA
1 12/17/03 12/17/03 AC-4 valving to alternate chillers and boilers need to be automated
1 1/14/04 Owner received quote from Cont.
At a minimum, we need some form of DDC indication as to the status of the position
1 1/15/04 1/16/04 of the manual valves if they are kept.
1 1/21/04 Cont. sequence is incorrect; house steam boiler is normal operation for MnAC4
Discuss valving requirements in meeting; Cont. proposed valving modification and
1 2/4/04 will develop sequence
1 2/27/04 Cont. sequence as submitted is incorrect. House boiler is primary supply for MnAC4.
1 3/10/04 Cont. submitted new sequence; QA to review and define point names
1 3/16/04 QA provided comments to Cont. and Taylor Engineering
1 3/24/04 Eng. asked if all information agreed upon.
MnAC4Chlr ChWP Run and MnAC4Blr HoWP Run should be interlocked with Xover
1 8/6/04 8/13/04 Valves. Eng. to provide specification revision.
Spec revision revised again and approved by QA and Eng.. Program is yet to be
1 10/19/04 installed. 10/21/04 - Program installed. Cont., (6) 10/19/04 QA
Does the MnAC4 Nortec Humidifier setpoint adjustment need to be automated? Eng.
2.1 1/15/04 1/15/04 to review; we at least need the setpoint monitored and a paged alarm Eng
2.1 3/24/04 Cont. to propose sequence for using the Nortec and dew point control. Cont.
2.1 8/4/04 No reset was implemented but Nortec status is monitored and alarms provided. QA
QA: Rotronics dew point sensor will not be used. Cont. to provide acceptable
2.2 4/7/04 alternate. Cont. QA
MnAC4: Need sequence for Standards lab if Chiller 1 is required to run. Mn Chiller
4 2/24/04 4/7/04 sequence modified 6/21/04 to maintain 42 deg.F if MnAC4 is on Team, (6) QA
19 4/27/04 MnAC4: Can TempSpAdj be eliminated? Yes QA
If MnAC4 Boiler Xovr Alarm is too be used it should only indicate if valves are
26 5/21/04 5/28/04 opposite Cont.
26 Alarm has been removed.
QA discussed with Cont.'s programmer the need to add a +/-4 deg F. hysterisis to QA
the MnAC4 ChWVlv and HoWVlv zone temp breakers. 4 and 2 are used
30 6/2/04 respectively. Cont. QA
MnAC4 ChWS and R sensors are grossly inaccurate. Calibrate & reinstall or replace
60 8/4/04 with better sensors.
Cont. indicates that theses have been recailibrated. ChWS Temp is ~ 9 deg. F
60 10/19/04 greater that chiller leaving temperature measured with a Pete's plug gauge.
MnAC4 ChWS and R sensors appear to be impacted by room temp. At cool bldg
temps (<65) the ChWST is close to the measured chiller leaving temp (37.5 ~ 38.8),
but as the building warms, the CHWST & RT rise, but the chiller leaving temp
doesn't. They need to be replaced with ones in thermal wells, preferably at the
60 10/20/04 chiller. Cont. 11/1/04
60 10/28/04 New sensors were installed in thermall wells at the coil. QA
Standards Lab panic button needs to be documented and functional tested.

MnAC5 1) economizer control logic is not the same as MnAC1(spec). 2) "or"
12 4/19/04 4/21/04 statement in econ lockout logic is miss wired. 3) RADmpr% trend wire is mislabeled Cont., (6) QA
MnAC5 4) DAT >> RAT and ChWVlv open, Fan Not Running! Why? Contractor had
been working around original pneumatic system downstairs, may have disturbed the
13 4/19/04 4/19/04 tubing. Unit is now cut over, but the old equipment still needs to be removed. Cont. QA
MnAC5: Air flow is inadequate at zone boxes, SF is manual and VFD is at 15% and
39 7/7/04 8/13/04 HiPresStatic Alarm is on.
39 8/4/04 8/13/04 Need HiPresStatic Alarm reset procedure for training and systems manual. See 17.2 above.
MnAC5SF is shutting down on Low Static Pressure during warm-up. Raul checked it
out. He thinks that the switch is defective. Will replace if it happens again. 11/21/04
126 11/9/04 MnAC1, 2 and 5 sensors are to be replaced. Cont. 12/3/04 QA
133 11/17/04 MnAC1 and MnAC2 need low pressure cutout per spec. Cont. 12/8/04 QA
MnAC5 RADmpr is being closed during warm-up. This impacts the fans ability to
136 11/22/04 heat the space. It appears this may also be true with MnAC1 and MnAC2. Cont. 12/3/04 QA
10 3/26/04 MnAC7: Temperature is rising across DX coil
MnAC7: This is because the system is recirculating air through the return duct, which
10 4/13/04 has been omitted from the graphic. (2)
MnAC7 and 8: Spec calls AC7 the unit that serves the cafeteria; the program says
that it is the unit that serves the kitchen. AC7 serves the kitchen. The spec needs
20 4/27/04 changed QA QA
MnAC7& 8: Is compressor cycling lockout part of equipment or does it need to be
21.1 4/27/04 4/28/04 installed in program? A five minute timer is in the program. Cont. 8/31/04 QA
MnAC7& 8: 2nd Stg Cooling PID range is not correct. 2nd stage cooling PID OK per
21.2 4/27/04 4/28/04 Eng. Cont. QA
MnAC7: why does stat display 2 numbers? Second number is for outside
22 4/27/04 5/19/04 temperature. It is now removed QA
Small AC units (MnAC7&8, Count Room AC, MetAC1,4,5 and WhAC1&2 all require
84 8/28/04 8/30/04 TempSpAdj trend wires to be added to FB Cont. 9/19/04 QA
Sensors currently installed in the Environmental Chambers will need to be replaced

MtAC3: RA Temp is not on original points list but is noted in the logic. Is this RAT of
63 8/6/04 8/13/04 another MAT in the heating duct? If real add to graphics in appropriate place. Cont. 8/31/04 QA
MtAC3 oscillates between Cool1 and Cool2. Increasing the delay timer to 15 minutes
on 9/1/04 did not reduce the oscillation. Increase cycle time if possible.
90 9/2/04 Eng.10/25/2004: 15 minute cycle is OK. Cont. 9/19/04 QA
MtAC3 warm-up and cool-down sequences currently allow the fans to run anytime
after 3:00AM when the building is unoccupied and other conditions permit. This
allows it to run on weeQAds. It should be using a schedule as MnAC1. Also, the
heating PID loop is not programmed as specified. 11/21/04 QA to check results of
updated program. QA 11/22/04: Cooling fan does not run during warm-up but
spaces do not come up to temp fast enough as hot air flow falls off. Cooling air-flow
comes on at occupancy even without a request for cooling. Cool air from bypass
damper cools hot air supply. Cont.'s programmer is in the process of fixing. QA
12/3/04: Looks correct. Final approved sequence needs to be put into the as-built
113 10/29/04 11/1/04 spec., see #106 above. Cont./Eng 12/3/04 QA
Even with the cool morning, MtAC5 needed cooling but it was locked out due to low
OAT. An OAT based cooling or heating lockout is not in the spec. (3.03.O.3).
Remember, these units do not have economizers. Remove lockout logic from

10/20/04 programming for all confusion over which unit is MtAC1 and MtAC5. When the Cont. 11/1/04 QA
Current Facilities Requirements doc was being developed Joe indicated to me that
MtAC5 provided conditioned air 24/7 to Mt109, where the SEM is located and Mt
108, the small room next door. MtAC1 provided conditioned air 6-6 M-F to the Met
lab in Room Mt106 and the darkroom adjacent to it in room Mt107. This later went
into the spec. Once the installation of DDC hardware was completed, Cont. techs
noted that this was backwards and programming and documentation was changed
accordingly, which includes my recent mark-up of the spec. Unfortunately, I believe
this may now be incorrect. Saturday, the Met color graphic indicated that the unit
supporting Mt106 was on not Mt109. A test of the zone overrides seemed to verify
this to be the case. This needs to be cleared up once and for all. Appropriate
changes, if necessary, will need to be made on graphic pages, point names,
schedules, equipment labels if need be, and in the CFR and Spec. 11/2/04:

53 10/1/04 10/19/04 QA: OK except MtDD-8 hot deck air flow is not reading - damper is at 100%
QA & DM investigated MtDD-8. Determined that spec requires Heating Supply Fan
to turn off if not required. The program currently switches between cooling airflow
and heating airflow depending on zone controller ouput, staying in heating until
cooling > 0. It provides no flow if still in heating (0%) when the heating fan turns off.

the boiler too small? No, No; new boiler reaches
temp quicker than HoWVlv can react, so temps cycle

DDC System Installation Project
ISSUES: Out of Scope ACTION REQUIRED Resolved
LOG By
We had been loosing data in the trends from time to time. Controls Mfg. said
that it could be a network configuration issue. Cont. to meet with IT to resolve.
We need to verify this condition does not return once the server is move to the
basement comm room. (4, 5) QA
MnAC3: once VAVs are operational and stat is installed, stat can be
programmed for 2hr override increments; note max time for this equipment is
224 minutes. Program update my be forthcoming from Controls Mfg. in
November to change this to 8 hours. Cont. Service Tech2 to notify us when it
is available. We may get this under warranty. QA 12/15/04: Installed ; need to
test. (4, 5)
MnAC4: Are we going to reset the Nortec based on outside %RH? Is reset
necessary? Eng.: Not unless dry winter conditions indicate that it is necessary.
QA 11/21/04: It appear we are over dehumidifying in winter. Consider resetting
coil leaving air temp based on hot water and humidifier PID > 25%. QA
11/29/04: Tried this wihtout much success as chiller operation impacts zone
temp stability. Need chiller with greater turndown. (3, 4, 5)
MnAC4 Chiller Setpoint is 45 deg.F. How is this physically set? It does not
always provide low enough chilled water to meet %RH setpoint; see 5/21/04
data. The chiller setpint is internal to the chiller. It is set at 38 deg.F leaving
water temp. Air handler may not have enough capacity. (3, 4, 5)
MnAC4 Chiller Comp 1 & 2 Alarms do not appear functional. Are these analog
or digital points? Per Cont. tech MnAC4Chiller Alarm outputs do not work (3, 4, 5)
MnAC7: Why does the SA temperature on cooling run so high? Does not get
below 58oF. This appears to be a mechanical issue. (3, 4 ,5)
Wining noise coming from VAV box 1-19 in Room 134 Main building. After 4
hours the noise went away and has not come back sense. 10/25/04: This may
be a warranty issue, but Owner's staff needs to help diagnose problem if it
happens again. Noise comes from a loose duct access cover. Operator2
installed a piece of cardboard to quiet it. (5) QA
York Gateway to be used to reset chiller leaving water temperature instead of
hard wire. 10/1/04 - Chilled water reset is being sent to and being received by
the York chiller but it does not appear to be functioning. Understand from York
that the control board in the chiller needs updating. (3, 4, 5)
House chiller chilled water pump currently cycles on/off under low load
conditions (currently after ~3 hours). Consider disabling the house chiller
based on cooling request and all ChWVlvs at 0%. QA 12/15/04: Control
program enables the chiller start sequence to run, which then turns on the
chilled water pump. The chilled water pump should stay on as long as the start
sequence is enabled. It is disabled once the all ChWValves are at 0%. Why
the pump has been staying on for an extended period of time beyond this
needs to be investigated. It also needs to be tested when MnAC4 on the house
chiller. (3, 4, 5)
MtAC3: CoSAT gets down to 38oF. This is too cold. Airflow may be difficient. (3, 4, 5)
MtAC2: 1st stage of heating does not appear to be functioning properly. SA
Temp is not warm up until 2nd stage operates. (3, 4, 5)
Main building heating hot water loop may need balancing. This could the
source of MnVAV2-6 and 2-7 capacity problems. Cont. has confirmed that the
newly installed valves were correct. HVAC.Maint.Cont. is scheduled to check
all strainers. (3, 4, 5)
