ALARM HANDLING - It shall be possible to declare alarms on every input. An analog input shall have
both low and high value alarms. Alarms shall be designated either “Critical” or “Warning” in the
subject field of the associated email message. All alarms shall be queued for transmission to the
operator terminal(s) and by email and logged with time tag, point label, current value, and alarm value
that was exceeded. The system buffer shall have a capacity for at least 100 alarms. Alarm
acknowledgement and restoration shall also log to the same terminal(s) as the alarms themselves.
.1
When a point goes into alarm, a user defined message of not less than 80 characters shall be
sent to the local operator console, alarm printer, or through internet email transmission to as
many email addresses as set up in the system. Response time from alarm occurrence to
delivery shall not exceed 5 seconds. When dialing out to an internet connection, the modem
shall wait for connection before sending the email message.
.2
The operator shall have the ability to disable any particular alarm to prevent it recurring during
unusual system operation.
.3

Set up and test the alarms specified in Section 15936.
CONCURRENT PROGRAM OPERATION - The operator terminal may be used for running other
software, such as a spreadsheet, word processor, or maintenance management database. The
system shall be capable of receiving and logging alarms in background while the other software is
running. Alarm messages shall appear or create an audible sound while the other program is running,
but shall not disrupt the other program. Microsoft Windows may be used to perform this multi-tasking,
so long as the operator terminal is supplied fully configured to allow operation as described.
CONTROL SEQUENCE LIBRARY - The system shall include facility for easy implementation of the
following features.
.1
COMMAND LANGUAGE - A high level command language shall include commands such as
Edit, Display, Delete, Graph, Copy, and Log for operating and programming the system.
.2
WEEKLY SCHEDULES - The system shall be capable of at least 60 on/off schedules for
assignment to outputs. Each schedule shall allow easy modification through the operator
terminal, and shall allow for annual holiday and special day (extended operation) overrides.
.3
HELP PROGRAM - The control software shall include a context-sensitive help service for
operator support. This shall be accessible at any time while still on-line with the network.
.4
DUTY CYCLING - The system shall have the possibility to easily assign duty cycling to any
stop/start output point. Each point shall have the possibility of both low and high temperature
limits to override the duty cycling. The operator will be able to define minimum off times and
minimum run times for each piece of machinery.
.5
PID SETPOINT CONTROL - The system shall have a standard control loop program that allows
the operator to assign the setpoint, the controlled input variable, and the controlling output or
outputs. This standard function shall use proportional-integral-derivative control to allow the
quickest possible settling time, the minimum overshoot, and no steady-state offset. The function
shall allow sequencing or staging of multiple outputs. It shall allow a knowledgeable operator to
change output sequence ordering, setpoint, proportional gain (Kp), time constants (Ti and Td), or
to lock out output stages without going into complex program code.
.6
PID RESET SETPOINT CONTROL - The system shall have a standard control loop program
with reset and all of the features described above under PID Setpoint Control. The reset feature
allows the operator to tie the setpoint value to another analog input. The setpoint will change as
the reset analog input changes. The function shall allow a knowledgeable operator to redefine
the reset curve by changing the defining endpoints, as shown in the diagram.
-10°C,80°C
In this example the endpoints are (-10°C, 80°C) and
(15°C,35°C). Below -10°C outside temperature,
heating water is controlled at 80°C. Above 15°C
outside temperature heating water is at 35°C. In
between -10°C and 15°C outside, the heating water
setpoint varies linearly between 80°C and 35°C.
15°C,35°C

ADAPTIVE OPTIMIZED STARTUP - Where a fan system is programmed for occupied mode /
unoccupied mode operation, the control system shall include the option for adaptive optimized
startup. With optimized startup enabled, the mechanical system shall go from unoccupied into
occupied mode earlier than scheduled. This early startup period shall be set and adjusted
Efficiency Engineering Inc. Aug-10
Section 15920 Page 46 of 60
.8
.9
automatically by the control system to bring space conditions into the occupied setpoint range
just at the scheduled start time. The control system shall adapt and optimize this startup using
historical outside temperature information and inside temperature response periods. Using this
technique, the building operators shall not have to schedule systems to start early anticipating a
lag between startup and comfort in the space.
ON-LINE SENSOR RECALIBRATION - The system shall have a facility whereby the operator
can use an external temperature or relative humidity reading to recalibrate a sensor. The
operator shall also have the ability to add an offset to any analog input for calibration purposes.
TOTALIZERS - Software counters shall be available to totalize the number of hours a piece of
equipment has been running or totalize an input, such as gpm into total gallons. The controller
shall totalize the number of starts of digital outputs since last reset. These values shall be
displayed, printed, reset, or downloaded to a disk file at any time, for use by plant personnel in
equipment maintenance. In addition, the operator shall be able to assign an upper limit value to
each point to produce a Notice Alarm message when a piece of equipment has run for the time
required between scheduled maintenance.

CONTROL SEQUENCE LIST
.1
Heating Boiler Plant
.1
Heating Pumps
.1
On a call for heat from the air-handling units F-1, F-2 or F-3, the distribution supply pump
P-1 shall cycle on and modulate its speed according to the on-board constant pressure
controls.
.2
When the distribution supply pump, P-1, is running and the boilers are called to fire the
boiler circulator P-2 shall cycle on and modulate its speed according to the on-board
constant pressure controls.
.3
The specified pumps are sensorless Integrated Variable Speed and shall be configured to
vary the speed using integrated controls to maintain a constant pressure at the pump
outlet.
.4
The pumps shall operate for one minute when they have been off for 24 hours.
.2
Heating Boilers
.1
To initiate the boiler firing sequence the boiler circulator P-2 shall start and the lead boiler
control valve shall open. Upon end-switch proof that the control valve is open the boiler
shall start.
.2
The heating boilers shall stage and the burners modulate to maintain the supply water
temperature setpoint, initially 150°F. To maintain setpoint, the lead boiler shall ramp up
slowly from minimum fire. The burner shall modulate to maintain setpoint with a throttling
range of 3°F. Under high load conditions, if the lead boiler fires at 100% for 15 minutes
and still cannot come within 2°F of setpoint, the second boiler will come on at minimum fire,
ramping up to 50% fire, while the lead boiler will drop to 50% fire. Then both boilers shall
ramp up slowly, modulating in parallel to maintain setpoint.
.3
When the operating group of boilers has operated at minimum fire for 15 minutes and the
control temperature exceeds setpoint by 2°F or more, then the last boiler in the sequence
shall be dropped and the control valve shall close. The remaining boilers will then
modulate to maintain setpoint.
.4

AMENDMENTS TO TENDER SPECIFICATIONS
Appendix B M1-2:
a)
Equipment schedule is missing details for new unit heater to be supplied by the
contractor. This one is a Modine HC-121 or equivalent.
Appendix B M1-2:
a)
Equipment schedule is missing details on the side stream filter to be supplied by
the contractor. This one is a Pall Corporation LMO with 3/4” NPT connections,
with filter cartridge.
ADD: THE FOLLOWING QUESTION AND ANSWER IN RED
The flexible connection between the existing fan burner section and the gasket
between the burner and fan section is made of asbestos fabric. How should this be
handled?
Contractor should include in quote to have it removed by a qualified contractor.
What materials should the new fan section be fabricated from? The duct is aluminum.
The existing fan looks to be mild steel.
Match existing fan cabinet material
What is the scope of work for air balancing ?
Not required.
The pool shutdown is until Sept 24, will the Arena be closed as well with the ice out
of the Arena rink until then?
1st ice rental is September 18th. Ice goes in the week before. All work requiring shut
down of refrigeration equipment to be complete before then.
M1-1 The controls air compressor is to be removed, do all the compressed air lines,
panels throughout need to be removed.
No need to have them removed but would “clean up” the room. The cost of doing so
shouldn’t be too big inside the mechanical room. Anything outside can remain.

MS.3 The new Flood Water Tank temp sensor is shown as immersion, the present
tank probably does not have a port for an immersion sensor is a strap on sensor
acceptable? The same condition exists for new tank points on MS.4 and MS.5.
strap ons are acceptable.
MS.5 Are the existing standalone staging controls on the compressors and cooling
tower and pump to be removed?
Yes
MS.5 2 ARN-ICT points are shown as existing, and one is shown as a note #2 part
of burner wiring. Is this correct? If they are new where would they be located in
relation to the ice surface and do they need to be in conduit.
These will be new infra-red sensors as specified. Location will be hung from ceiling
or rafter. These were incorrectly marked as existing.
15920 3.2 Conduits- Much of the existing exposed wiring is not in conduit, can that
wiring be reused but use conduit for the new points?
There is no cost benefit to using new conduit. We specify reuse of conduit and
wiring assuming conduit is in place. This is really your decision.
