GENERAL

SUMMARY

Provide a complete Direct Digital Control (DDC) system, suitable for the control of the heating, ventilating and air conditioning (HVAC) and other building-level systems as specified and shown and in accordance with Section 23 09 13 INSTRUMENTATION AND CONTROL FOR HVAC.
The new DDC system shall be Honeywell or approved equal to allow seamless connection into the existing Honeywell base front end. The Temperature Control Contractor shall verify exact base front end with the COR before starting any work. Before the start of construction, the Temperature Control Contractor shall meet with the Base EMCs Supervisor to discuss recovery of existing working controls that are removed from the building. All installed control systems shall be connected to the existing base wide Civil Engineering Community Of Interest Network Enclave (CE COINE). The control systems shall be programmed into the base wide Honeywell Enterprise Building Integrator (EBI) and front end graphics updated to reflect new work and control sequences. Contractor shall contact and coordinate connections with the CE IAM. All new and replacement building level controllers shall be Honeywell Comfort Point Open CPO-PC-6A. 1.1.1

System Requirements

Provide a system meeting the requirements of both Section 23 09 13 INSTRUMENTATION AND CONTROL FOR HVAC and this Section and with the following characteristics:
a.

Except for Gateways, the control system must be an open implementation of BACnet technology using ASHRAE 135 and Fox as the communications protocols. The system must use standard ASHRAE 135 Objects and Properties. The system must use standard ASHRAE 135 Services exclusively for communication over the network. Gateways to packaged units must communicate with other DDC hardware using ASHRAE 135 or the Fox protocol exclusively and may communicate with packaged equipment using other protocols. The control system must be installed such that any two ASHRAE 135 devices on the internetwork can communicate using standard ASHRAE 135 Services.

b.

Install and configure control hardware to provide ASHRAE 135 Objects and Properties as indicated and as needed to meet the requirements of this specification.

c.

Use standard BACnet hardware and software exclusively for scheduling, trending, and communication with a front end (UMCS). Use standard BACnet Objects and services for alarming. Use the ASHRAE 135 protocol
