CAUTION
REDUCED FURNACE LIFE HAZARD
Failure to follow caution instructions may result in
reduced furnace life.
Do NOT exceed 115V/0.8 amp. maximum current
load for both the EAC terminal and the HUM
terminal combined.
Control Center Fuse
The 24V circuit contains a 5-amp, automotive-type fuse iocated
on fan timer board. (See Figure 33) Any electrical shorts of 24V
wiring during installation, service, or maintenance may cause fuse
to blow. If fuse replacement is required, useonly a fuse of identical
size (5 amp.)
NOTE: The humidifier will be powered when the furnace is fired
and the circulating air blower comes on. The electronic air cleaner
will be powered anytime the air circulating blower is energized.
However, the electronic air cleaner is NOT energized during con
tinuous fan operation controlled by the electronic fan control.
Fan Control
The fan control is preset at the factory with a fixed blower ON delay
of 30 seconds in the heating mode. The blower OFF timing is pre
set at 140 seconds. If desired, the fan OFF delay can be reset to
obtain the longest delay times while still maintaining comfort lev
els. See "Furnace Wiring Diagram".
