Guide Specifications (Continued)
m. The control shall have the ability to temper the
ventilation air during times when heating or cool
-
ing is not required.
n.
The control must be able to lock out cooling be
-
low a programmable OAT setpoint.
o.
The control shall be able to lock out heating
above a programmable OAT setpoint.
p. The control shall be able to do a pre-occupancy
purge.
q. The control shall have purge, de-pressurization,
and pressurization sequence for smoke control.
r. The control shall have the ability to read pressure
across two filter banks.
s. The control shall have the capability of reading a
fan proving switch.
t. The control shall have an intelligent recovery func-
tion that shall bring the space to the occupied set-
point just before or at the beginning of the first oc-
cupied schedule each day. The control shall learn
and apply the minimum run time required to heat
or cool the space to setpoint for the first occupied
period of a day. The unit controller shall be capa-
ble of compensating start time based on OAT.
u. The control shall satisfy cooling demand using
unequal compressor staging combinations.
v. The control shall have ability to enable the ERW.
w. The control shall monitor the outside airflow.
x.
The control shall provide a low ambient cooling
operation.
y. The control shall enable either dehumidification,
humidification, or temperature cool-only mode
based on humidity setpoint.
z. The control shall have compressor safety moni-
toring.
aa. The control shall have FDD alarm monitoring for
economizer operation.
ab. The control shall provide UV light replacement
warning after certain runtime hours.
ac.
The control shall monitor exhaust air/return airflow.
ad. The control shall provide rapid start.
ae.
The control shall be capable of initiating warm-
up/cool down mode using either occupied com
-
mand, optimal start or schedule.
af. The control shall provide staggered start and
coast mode.
ag.
The control shall provide condensate overflow
switch alarm.
BAS Communications
The unit shall have BACnet MS/TP, Modbus, N2 [BACnet
IP] communication protocol integral to the unit controller.
The controller shall be certified for BACnet communication
protocol by BACnet Testing Laboratory (BTL) to meet the
requirements of the advanced application control profile.
A control points list, BACnet interoperability building
blocks (BIBBs), and protocol implementation conformance
statement (PICS) shall be provided by the manufacturer to
facilitate communications programming with the BAS.
1.
Mobile Access Portal (MAP) Gateway [Optional] -
MAP Gateway is a pocket-sized web server that shall
provide a wireless mobile UI to Smart Equipment and
manufacturer branded system controllers and ther-
mostats. MAP Gateway shall provide multi-client
connectivity, browser-based interface,
WiFi connec-
tivity, browser-based remote building management,
permanent audit log, portable size and mobility, and
an easy-to-use intuitive UI.
2.
BAS Interface Board [Optional] -
A BAS interface
board shall be supplied on all units requiring twinning,
smoke control sequences, [humidifier], or [hydronic
heat].
3.
Verasys
™
and Metasys
®
Communication Interface
The BAS shall provide the owner with a simple user
experience and configurable controls. The system
shall consist of Smart Equipment technology and
shall be capable to interface with Verasys
™
and Meta-
sys
®
systems.
