User interface
The PremierLink™ controller is designed to allow a service person or building owner to configure and operate the unit through the CCN user interface. A user interface is not required for day-to-day operation. All maintenance, configuration, setup, and diagnostic information is available through the Level II communications port to allow data access by an attached computer running Network Service Tool, ComfortVIEW™, or ComfortWORKS® software. Data access also can be obtained from System Pilot™ or Touch Pilot™ devices.
Wiring connections
Field wiring is 18 to 22 AWG (American Wire Gage). The PremierLink controller is a NEC (National Electrical Code) Class 2 rated device.

Power supply
2-wire, 24 VAC ± 15% at 40 va, 60 Hz
Power consumption
Normal operating supply range is 18 to 32 VAC with minimum consumption of 10 VA
Hardware (memory)
Internal flash memory of 64K
Specified sensing temperature range
The PremierLink controller space temperature range is –40 to 245 F (–40 to 118 C). The PremierLink controller has an allowable control set point range from 40 to 90 F (4 to 32 C) for heating and 45 to 99 F (7 to 37 C) for cooling.
Communications
The number of PremierLink controllers is limited only by the maximum number of controllers allowed on a CCN system. Bus length may not exceed 4000 ft (1219 m), with no more than 60 devices on any 1000 ft (305 m) section. Optically isolated RS-485 repeaters are required every 1000 ft (305 m). Status and control data is transmitted at a baud rate of between 9600 and 38.4K.
Activity indicators
Two activity indicators present on the PremierLink controller indicate activity. A green LED will indicate activity on the communication port and a red LED will indicate status of processor operation.
