2000 VA maximum connected load to relay module.
c
Honeywell has tested this output at 9.8A at PF = 0.5, 58.8A inrush for 100,000 cycles
(EN298 approval does not require this test).
d
Total load current, excluding Burner/Boiler Motor and Firing Rate Outputs cannot exceed 5A, 25A inrush.
e
Total load current, excluding Burner/Boiler Motor and Firing Rate Outputs cannot exceed 5A, 25A inrush for 250,000 cycles.
f
Can also be 24 Vac, 3A at PF = 0.5.
g
220/240 Vac to 120 Vac, 10 VA stepdown transformer (not provided) must be used to drive the shutter.
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death, or property
damage.
Close all manual fuel shutoff valves before starting this
test to prevent an explosion.
