Accessory Terminals
One line voltage "EAC" 1/4" spade terminal is provided on
the furnace integrated control. See figure 59 for integrated
control configuration. This terminal is energized when the
indoor blower is operating. Any accessory rated up to one
amp can be connected to this terminal with the neutral leg
of the circuit being connected to one of the provided neu-
tral terminals. If an accessory rated at greater than one
amp is connected to this terminal, it is necessary to use
an external relay.
One line voltage "120 HUM" 1/4" spade terminal is pro-
vided on the furnace integrated control. See figure 59 for
integrated control configuration. This terminal is energized
in the heating mode when the combustion air inducer is
operating. Any humidifier rated up to one amp can be con-
nected to this terminal with the neutral leg of the circuit be-
ing connected to one of the provided neutral terminals. If
a humidifier rated at greater than one amp is connected to
this terminal, it is necessary to use an external relay relay.
One 24V "H" 1/4" spade terminal is provided on the fur-
nace integrated control. See figure 59 for integrated con-
trol configuration. The terminal is energized in the heating
mode when the combustion air inducer is operating and
the pressure switch is closed. Any humidifier rated up to
0.5 amp can be connected to this terminal with the ground
leg of the circuit connected to ground or the "C" terminal.
Install the room thermostat according to the instructions
provided with the thermostat. See figure 58 for thermostat
designations. If the furnace is being matched with a heat
pump, refer to the FM21 installation instruction or appro-
priate dual fuel thermostat instructions.
Indoor Blower Speeds
1 - When the thermostat is set to "FAN ON," the indoor
blower will run continuously on the fan speed (FAN)
when there is no cooling or heating demand.
2 - When the EL195UHE is running in the heating mode,
the indoor blower will run on the heating speed
(HEAT).
3 - When there is a cooling demand, the indoor blower
will run on the cooling speed (COOL).
Generator Use - Voltage Requirements
The following requirements must be kept in mind when
specifying a generator for use with this equipment:
• The furnace requires 120 volts + 10% (Range: 108
volts to 132 volts).
• The furnace operates at 60 Hz + 5% (Range: 57 Hz
to 63 Hz).
• The furnace integrated control requires both po-
larity and proper ground. Both polarity and proper
grounding should be checked before attempting to
operate the furnace on either permanent or tempo-
rary power.
• Generator should have a wave form distortion of
less than 5% THD (total harmonic distortion).
