Accessory Terminals
One line voltage "EAC" 1/4" spade terminal is provided on
the furnace integrated control. See figure 58 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 neutral
terminals. If an accessory rated at greater than one amp is
connected to this terminal, it is necessary to use an exter­
nal relay.
One line voltage "120 HUM" 1/4" spade terminal is pro­
vided on the furnace integrated control. See figure 58 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 furnace
integrated control. See figure 58 for integrated control con­
figuration. The terminal is energized in the heating mode
when the combustion air inducer is operating and the pres­
sure 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 instruc­
tions provided with the thermostat. See figure 57 for
thermostat designations. If the furnace is being
matched with a heat pump, refer to the FM21 installa­
tion instruction or appropriate dual fuel thermostat in­
structions.
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:
D The furnace requires 120 volts + 10% (Range: 108
volts to 132 volts).
D The furnace operates at 60 Hz + 5% (Range: 57 Hz to
63 Hz).
D The furnace integrated control requires both polarity
and proper ground. Both polarity and proper grounding
should be checked before attempting to operate the
furnace on either permanent or temporary power.
D Generator should have a wave form distortion of less
than 5% THD (total harmonic distortion).
