Lennox ELITE EL196UHE Installation Instructions Manual page 40

One 24V "H" 1/4" spade terminal is provided on the fur-
nace integrated control. See Figure 60 or 61for integrat-
ed control configuration. The terminal is energized in the
heating mode when the combustion air inducer is operat-
ing 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 in-
structions provided with the thermostat. See Figure 59 for
thermostat designations. If the furnace is being matched
with a heat pump, refer to the thermostat installation in-
struction 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 17 on page 55 for allowable circulation
speeds.

Low Line Voltage
A "Heartbeat" is indicated by a "Slow Flash" - 1 sec on 1 sec off, repeating
Error codes are indicated by a "rapid flash" - the LED flashes X times at ½ second on ½
second off, remains off for 3 seconds then repeats.
Last 10 error codes are stored in memory including when power is shut off to the
unit. - To recall, pressand release button, most recent will be displayed first, LED off for 3
sec, then next error code is displayed, etc. To clear error codes, depress and hold button
longer than 5 seconds.
2 - When the EL196UHE is running in the heating
mode, the indoor blower will run on the heating
speed (HEAT). See TABLE 16 on page 55 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 tem-
porary power.
• Generator should have a wave form distortion of
less than 5% THD (total harmonic distortion).
