A.1 OVERVIEW The contractor shall furnish, install, and place in operating condition a Programmer Control as described herein. The system shall be located in accordance with these specifications.

A.2 TYPE OF SYSTEM

A.2.1 Major functions of the Programmer Control shall provide: a. Automatic sequencing of the burner system through Initiation, Standby, Prepurge, Pilot Flame

Establishing Period, Main Flame Establishing Period, Run, and Postpurge.

b. Flame proving and lockout on flame failure during pilot flame proving, main flame proving, or run.

c. Low fire firing rate motor position for flame ignition trials.

d. Modulating switching control of fuel and combustion air.

e. Status light emitting diodes (LEDs) indicating:

• Power present, green.

• Main valve energized, yellow.

• Alarm, red.

• Pilot valve, yellow.

• Flame present, red.

f. NEMA 1 rated enclosure.

g. Line voltage terminal inputs for lockout, preignition, and recycle limits and interlocks.

h. Separate annunciation faults including Programmer Control, flame failure, preignition interlocks,lockout interlocks and firing rate interlocks.

i. Self-test for proper operation.

j. Monitor system circuit status.

k. Tamper resistant safety logic and timing.

l. First-out annunciation and diagnostics including display of flame signal, total burner cycles, burner

hours, fault history of last six lockouts, and diagnostic voltage tests of burner I/O via a vacuum fluorescent display (VFD). The VFD shall be able to be mounted remotely within 1000 feet of the Programmer Control.

m. Nonvolatile lockout and history files.
