E.
Provide and install and fully commission a complete system of Automatic Temperature Controls as
specified herein, and as illustrated on the contract drawings to allow for a complete and operational
temperature control system. The Temperature Control system shall be a combination electronic Direct
Digital Control (DDC) with pneumatic actuation. All necessary control panels, relays, switches, system
software, valves, valve actuators, sensing devices, and damper operators shall be provided, installed,
and commissioned to insure proper operation of the temperature control system as detailed in the
sequence of operation, whether noted on the plans and specifications or not. The systems shall be
properly connected, piped and wired in a manner conforming to the laws, ordinances and codes now in
force in the Commonwealth of Kentucky.
F.
The facility management system (FMS) specified for this project shall seamlessly interface to the existing
Johnson Controls Metasys, facility management system. If the existing facility management system
cannot meet the requirements specified in this section, the controls manufacturer shall provide all
hardware, software, installation, control wiring, engineering and programming etc. to upgrade the existing
facility management system to meet the requirements of this section. All new and existing manufacturers
specific hardware points, software points, DDC controllers, Network Controllers, Workstations and
software system objects shall be monitored, controllable and accessible as described in this section from
either the Johnson Controls ADX Operator Workstation, located in the Peterson Service Building Delta
Room. Providing additional computer workstations, Internet IP Protocol Access, Java script programming,
windowing between different or loading separate facility management system software on one of the
above Workstations for interface to the new and existing facility management system is not acceptable.
G.
The facility management system shall interface to the existing Campus FDDI segmented WAN network
via 10BASET communication hub(s). With respect to all new and existing DDC controllers, Network
Controllers and workstations communicating over the campus WAN network, all control points and
software features described in this section shall be operable from one of the existing operator terminals
located in the Peterson Service building. Modem communication is not acceptable for this application.
There shall only be one physical connection to the campus FDDI WAN network.
H.
All controller programs shall have the ability to download and upload over the campus Ethernet network.
I.
UK Communications department shall provide all required HUB’s routers and switches required to
interface to the campus WAN network. The cost for this work shall be included by the controls
manufacturer. Obtain pricing from the UK Campus Communication Department prior to bid.
J.
EMS Connections to Third Party Equipment: Provide these connections and points as indicated in the
Sequence of Operation and/or the I/O Summary Sheets. Third Party equipment includes but is not limited
to, computer room air conditioning units, condensate pumps, transfer switches, HVAC variable speed
pumping systems, sump pumps, fire alarm systems, lighting systems, etc.

K.
Coordinate with third party equipment suppliers to determine equipment devices, such as, printed circuit
boards, contacts, etc. required for EMS connections. Provide any necessary connection devices not
provided by the third party equipment suppliers.
L.
Electrical power wiring and interlock wiring for all controls, signal devices, alarms, etc., shall be in
accordance with diagrams and instructions from the supplier of the systems. All power and control wiring,
conduit and wiring connections required for the complete installation, including wiring to smoke dampers
and combination fire/smoke dampers and their motors, shall be provided by this Contractor in accordance
Electrical 16 specification requirements.
M.
Refer to 15525d01 drawing standard.
GENERAL/PHYSICAL
Flow Computer:
Microprocessor based system
Flow Media:
Treated Chilled Water
Pipe:
inch O.D (nominal)
inch I.D. (nominal)
