Accessory Terminals
One line voltage "EAC" 1/4" spade terminal is provided on
the furnace integrated control. 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 pro-
vided neutral 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. This terminal is
energized in the heating mode when the combustion air
inducer is operating. Any humidifier 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 a humidifier rated at greater than one amp is
connected to this terminal, it is necessary to use an exter-
nal relay
One 24V "H" 1/4" spade terminal is provided on the furnace
integrated control. 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 61 for thermo-
stat designations. If the furnace is being matched with a
heat pump, refer to the thermostat installation instruction
for set up.
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. See
TABLE 16 on page 54 for allowable circulation
speeds.
2 - When the EL195UHNE is running in the heating
mode, the indoor blower will run on the heating speed
(HEAT). See TABLE 15 on page 54 for allowable
heating speeds.
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).
