B C D E F FEATURES HEATING SYSTEM SilentComfort Technology Patent pending burner sound enclosure and extra cabinet insulation reduces operating sound levels. Lennox Duralok Heat Exchanger Assembly Heavy gauge aluminized steel heat exchanger. Crimped seam clamshell type design. Designed for normal expansion and contraction. Minimum resistance to air flow. Heat exchanger has been laboratory life cycle tested in excess of industry standards. Compact size of heat exchanger permits low overall design of furnace cabinet. Inshot Burners Aluminized steel inshot burners provide efficient, trouble-free operation. Burner venturi mixes air and gas in correct proportion for proper combustion. Burner assembly is removable from the unit as a single component for ease of service. SureLight Hot Surface Ignitor Tough, reliable, long-life, trouble-free performance. Silicon nitride ignitor. 0 volt. Cemented to steatite block for protection against current leakage. Ignition leads are constructed of nickel plated copper and are enclosed in high temperature Teflon insulation for dependable operation. Two-Stage Gas Control Valve 4 volt redundant combination two-stage gas control valve combines manual shut off switch (On-Off), automatic electric valve (dual) and gas pressure regulation into a compact combination control. Two- Combustion Air Inducer Heavy duty, permanent split capacitor (PSC) two-speed blower prepurges heat exchanger and safely vents flue products. Dual pressure switches (low fire/high fire) prove blower operation before allowing gas valve to open. Operates only during heating cycle. G H I Flame Rollout Switch Manual reset switch is factory installed on burner box. Switch provides protection from abnormal operating conditions. Limit Controls Automatic reset, primary and secondary limits are accurately located. Primary limit factory installed on vestibule panel on all units, secondary limit factory installed on blower housing. Optional Accessories Altitude Pressure Switch Kit Required on most units for proper unit operation at altitudes from 450 to 0,000 ft. Natural Gas to LPG/Propane Conversion Kit Required for field changeover from natural gas to LPG/ Propane. LPG/Propane to Natural Gas Conversion Kit Required for field changeover from LPG/Propane to natural gas. BLOWER Variable Direct Drive Blower Each blower assembly statically and dynamically balanced. Change in blower speed is easily accomplished by simple DIP switch change on the furnace control. See Blower Performance tables. Blower assembly easily removed for servicing. Variable Blower Motor Variable speed motor maintains specified air volume from 0 though 0.8 in. w.g. (heating) and 0 through.0 in. w.g. () static range. Variable speed operation is achieved by the use of an ECM (Electronically Commutated Motor) motor. Motor is controlled by furnace control. Motor is resiliently mounted. When furnaces are used with the iharmony Zoning System and the icomfort Communicating Thermostat, the blower motor operates from predetermined minimum - maximum air volumes to satisfy zone requirements. SL80DFV / Page 3
FEATURES J CONTROLS SureLight Control (icomfort Communicating) Advanced control communicates information about various operating parameters in the furnace to the optional icomfort Communicating Thermostat to constantly maintain the highest level of comfort and performance available. Auto Configuration - On startup the control automatically sends a description of the unit to the optional icomfort Communicating Thermostat to automatically configure the number of stages and features available. Connections for connecting a conventional heating/ cooling thermostat are also provided on the control. Control also features Innovative AirFlex technology allows custom blower settings based on the application. Thermostat Control - For optimal performance, the use of a high-quality, digital two-stage thermostat with adjustable settings for first stage/second stage, on/off differentials and adjustable stage timers is recommended. Furnace Input Staging Options Thermostat Type Input Staging Available icomfort Communicating Thermostat Two-Stage (Conventional) Single-Stage (Conventional) Two-Stage (65 and 00%) Safety Controls - Flame sensor utilizes flame rectification for safe and reliable operation. Should flame fail to ignite, control will initiate 4 reattempts at ignition before locking out unit operation for 60 minutes. Watchguard type circuit automatically resets ignition controls after one hour of continuous thermostat demand after unit lockout, eliminating nuisance calls for service. Display LED - Seven segment LED displays alphanumeric information related to diagnostics as well as system operation and status. Diagnostic codes are held in non-volatile memory, immune from power interruptions. Holds up to ten diagnostic codes in order of occurrence for recall on demand. Port on blower door allows for easy viewing. Select Thermostat used - Single-Stage or Two-Stage. Two selectable second stage recognition times (7 and minutes) are available on the control when the furnace is used with a single-stage thermostat. When used with a two-stage thermostat, furnace will only initiate second stage operation with a second stage thermostat demand. Heating s - A combination of DIP switch settings allow the following motor speed selection settings within the heating speed selected for fine tuning air volume: Factory default 6%, %, 8% or 4% increase 6%, % or 8% decrease See Blower Performance tables. s - A combination of DIP switch settings allow the following motor speed selection settings within the cooling speed selected for fine tuning air volume: Factory default 0% increase 0% decrease See Blower Performance tables. Blower Ramping ( Mode) - DIP switch settings allow one of four blower speed profiles during cooling operation. Profile A (factory setting) - Motor runs at 50% for 30 seconds, then at 8% for 7-/ minutes, then at 00% (if needed) until demand is satisfied. Once demand is met, motor runs at 50% for 30 seconds, then ramps down to stop. Profile B - Motor runs at 8% for 7-/ minutes and then at 00% (if needed) until demand is satisfied. Once demand is met,motor ramps down to stop. Profile C - Motor runs at 00% until demand is satisfied. Once demand is met, motor runs at 00% for 60 seconds, then ramps down to stop. Profile D - Motor runs at 00% until demand is satisfied. Once demand is met, motor ramps down to stop. Dehumidification (Active or Humiditrol Option) - A jumper on the control control must be clipped to enable active dehumidification and/or operation with a Humiditrol Whole-Home Dehumidification System. A humidity controlling thermostat or device is also required. During a call for cooling, air volume is automatically reduced, forcing humidity removal by the air conditioner or heat pump system. After the humidity has reached the desired set-point the cooling air volume returns to its designed rate. A dehumidification signal from the thermostat reduces the cooling cfm to 70% of the requested cooling cfm. SL80DFV / Page 4
FEATURES CONTROLS (continued) Dual-Fuel Operation - A jumper on the control must be clipped to enable operation with a single or two-stage heat pump. The indoor blower is started without delay when a call for heat is received. Two-Stage Compressor Operation - A jumper on the control must be clipped to enable operation with a two-stage compressor. The cooling blower speeds for first and second stage cooling will be dictated by the applicable DIP switch settings. Lennox System Operations Monitor Connection - Monitors outdoor unit operation (communicating mode). Blower On/Off Time (Heating) - Blower on time is fixed at 30 seconds, blower off time is adjustable from 60, 90, 0 and 80 seconds (factory setting - 90 seconds). Blower On/Off Time () - For air-conditioning applications, blower on time is seconds following thermostat demand for cooling. See Blower Ramping ( Mode) profiles for various blower off details. Controls evaporator humidity by controlling blower and compressor speed on two-stage outdoor units when used with the icomfort Communicating Thermostat or the ComfortSense 7500 Thermostat. Continuous Blower - Adjustable continuous blower speed is a percentage of the high cooling speed selection. There are four selectable options (via DIP switch settings) of 8%, 38% (default setting), 70% and 00%. Accessory Terminal - One accessory terminal furnished for additional power supply requirements for 0 volt (less than amp) powered air cleaners. One unpowered pair of contacts are provided for humidifier connections and may be connected to 4V or 0V.
