module. The blower is energized directly through the
“inducer” terminals F1 and F2 of the (Fenwal) ignition
module. The 24V power to the T’STAT terminal of
the ignition module(s) are routed through the safety
interlocks.
The ladder diagram for models 1250, 1500, 1750
and 2000 is shown in Figure 13. These models have
two ignition modules, each with its own blower, and
each controlling part of the input so that startup at
reduced input is provided. The blowers are energized
by the ignition modules indirectly via switching
relays. When either ignition module receives a call for
heat, it switches its blower to high speed and the
blower of the idle ignition module to low speed.
The wiring schematic for the PowerMax 500 –
1000 is shown in Figure 14, and the schematic for the
1250 – 2000 models is shown in Figure 15. All 24V
wiring is routed through the diagnostic PC board.
Wiring harnesses connect between the diagnostic PC
board and the control components, indicator board, or
field wiring terminal strip. The diagnostic board
contains LEDs that indicate open status of the safety
interlocks, and quick-connect terminals that provide
tests points for checking voltage/continuity at various
points in the control circuit.
Certain control elements that may need to be
rewired in the field are connected via the field wiring
terminal strip rather than to the diagnostic PC board.
These include the low-water cutoff (LWCO), external
alarm, and water flow switch.
