dual-duct terminal unit, fan-coil unit, zone heat pump, etc.).
.2 The terminal unit controllers (TUCs) shall incorporate all of the requirements
for the stand-alone panels (SAPs), except for peer to peer communications
and auto-networking provisions.
.3 The auto-networking requirements defined for SAPs apply between the TUC
and the SAP it is connected to. If the TUC is connected to the main peer to
peer communication network, the full requirements apply.
System Display and Processing Speed
.1
.2
For multi SAP systems, the system processing speed is intended to address
inter-SAP communications and will be checked during the commissioning
phase by evaluating value updates from one SAP as received and displayed
in another SAP. This will be done by setting up a display of all SAP counters
and checking how frequently each counter is updated on the refreshed display
on site
Every counter shall show an updated value on the display within TWENTY
(20) seconds of the previous update value appearing. Provide confirmation

software program manually. To accomplish this, an off-line disk storage device shall be
utilized to provide software backup and reload.
.2 On-site backup and verification of the entire system, with full applications software,
shall be less thanTWO (2) seconds per real point. This feature will be checked during
commissioning stage.
.3 Explain in the Proposal how the back up is accomplished.
Memory
.1
Each SAP on the main network proposed shall have enough random access
memory (RAM) for all of the following:
.1 Trend Logs - One and a Half (1.5) TL for each input and output point
connected to the SAP with 100 samples each.
.2 Controllers - TWO (2) for each analog output point connected to the SAP.
.3 Software Points - THREE (3) for each output point connected to the SAP.
.4 Operator Control Language (OCL) - TWENTY (20) syntactically correct lines
each with at least 4 operators, for each output point connected to the SAP.
.5 Descriptor - ONE (1) for each user definable point, real or software, in the
SAP. In addition, on multi-SAP systems, every descriptor in the system must be
accessible from every operator interface device.
.6 Time Schedules - ONE (1) for every 3 output points connected to the SAP.
.7 Totalizers - ONE (1) for each digital point in the SAP.
.8 In the event there are TUCs networked to the SAP, which do not have their
own memory meeting items .1 through .7, the SAP must have full memory for all
TUC points as well as points connected directly.
.9 Provide with Proposal, calculations which confirm the foregoing RAM
requirements are met for each SAP.
SAP Processing Speed
.1 Effective SAP Processing Speed - Maximum permissible execution time is TWO
(2) seconds. Execution time is defined as the time it takes the SAP CPU to
execute all application software in the SAP, with no system timing errors, from
some point in the software back to the same point, assuming full memory usage,
as defined in Clause 4.5 above, while simultaneously responding to operator or
terminal display requests and carrying out normal inter-SAP communications
averaged over a ONE (1)-minute period. This will be done during the
commissioning phase by setting up a counter in each SAP and monitoring their
counting rate.
System Display Speed
.1
The minimum time to change from one dynamic screen to another is 7
seconds. This test will be carried out from a remote site with the standard
modem and will be the average of 10 typical displays for the project. Tests will be
carried out with the specified system configuration, excluding multi-user and
alarming functions.

CENTRAL BOILER PLANT
.1 Plant Description
Central boiler plant is a multiple boiler high temperature hot water heating plant with
three primary heating distribution zones, west, north-east and south-east. All boilers are
connected to common supply and return main headers. Each boiler has a water
circulating pump providing constant water flow for the boiler. The heating zones are fully
independent with independent connections to the main headers and independent zone
circulating pump groups. The heating zones operate as variable temperature variable
flow systems. The supply temperature is calculated in relation to an outdoor air
temperature schedule. The resulting supply water temperature set point is corrected in
relation to the temperature differential between the supply and the zone return water
temperatures. The zone pump variable frequency drives modulate the zone pump
speeds between the set minimum and full speeds to maintain the set pressure
differential between the supply and return system piping in the end mechanical rooms of
three heating zones.
