BLOWER Variable Speed Direct Drive Blower Each blower assembly statically and dynamically balanced. Change in blower speeds is easily accomplished by simple DIP switch changes on the SureLight control. See Blower Performance tables. Blower assembly easily removed for servicing. Variable Speed Blower Motor Variable speed motor maintains specified air volume from 0 though 0.8 in. w.g. (heating) and 0 through 1.0 in. w.g. (Cooling) static range. Variable speed operation is achieved by the use of an ECM (Electronically Commutated Motor) motor. Motor is controlled by the SureLight® Control. Motor is equipped with ball bearings and is resiliently mounted. When furnaces are used with the iHarmony® Zoning System and the iComfort® S30 or iComfort Wi- Fi® Thermostat, the blower motor operates from predetermined minimum - maximum air volumes to satisfy zone requirements. I J FEATURES SLP98UHV / Page 5 CONTROLS Surelight® Control (iComfort™ Compatible) Advanced control communicates information about various operating parameters in the furnace to the optional iComfort® S30 or iComfort Wi-Fi® Thermostat to constantly maintain the highest level of comfort, performance and efficiency available. Auto Configuration - On start-up the control automatically sends a description of the unit to the optional iComfort® S30 or iComfort Wi-Fi® 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. Precise Comfort Technology™ automatically adjusts blower speed and heat input in increments as small as 1% or as large as needed for greater temperature control. Variable-speed combustion air inducer is controlled by the Surelight Control. Prior to ignition, a pre-purge cycle for 15 seconds is initiated. After the main burners are turned off, a post-purge cycle for 20 seconds is run. Thermostat Control - Designed to operate in a variable capacity mode. The unit will automatically adjust firing rate based on demand and changing conditions. 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® S30 or iComfort Wi-Fi® Thermostat Variable Capacity (increments as small as 1%) Four Stage (35, 60, 80, 100%) Two-Stage (Conventional) Variable Capacity (increments as small as 1%) Two-stage (70% and 100%) Single-Stage (Conventional)Three-Stage (35%, 70% and 100%) SureLight® Ignition Control - Ignition control continuously monitors line voltage and maintains the igniter power at a constant level to provide consistent lighting and maximum igniter life. K Safety Controls - Flame sensor utilizes flame rectification for safe and reliable operation. Should flame fail to ignite, control will initiate 4 re- attempts 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 alpha- numeric 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. DIP Switch Settings (Note - DIP switches settings are not used with iComfort® S30 or iComfort Wi-Fi® Thermostat) Select Thermostat used - Single-Stage or Two-Stage. Select Operation Mode - Two-Stage, Three-Stage or Variable Capacity. Two selectable second stage recognition times (7 and 12 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 Speeds - A combination of DIP swtich settings allow Normal, 7.5% increase, 15% increase, 7.5% decrease or 15% decrease motor speed selection within heating speed selected for fine tuning air volume. See Blower Performance tables. Cooling Speeds - A combination of DIP switch settings allow Normal, 10% increase or 10% decrease motor speed selection within cooling speed selected for fine tuning air volume. See Blower Performance tables. Blower Speed Ramping (Cooling 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 82% for 7-1/2 minutes, then at 100% (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 82% for 7-1/2 minutes and then at 100% (if needed) until demand is satisfied. Once demand is met,motor ramps down to stop. Profile C - Motor runs at 100% until demand is satisfied. Once demand is met, motor runs at 100% for 60 seconds, then ramps down to stop. Profile D - Motor runs at 100% until demand is satisfied. Once demand is met, motor ramps down to stop. FEATURES SLP98UHV / Page 6 CONTROLS (continued) 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. 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 Time (Heating) - Blower on time is fixed at 30 seconds, blower off time is adjustable from 60, 90, 120 and 180 seconds (factory setting - 90 seconds). Blower Off Time (Cooling) - For air-conditioning applications, blower on time is 2 seconds following thermostat demand for cooling. Blower off delay is 30 seconds at 50% of high cool cfm (factory default). Controls evaporator humidity by controlling blower and compressor speed on two-stage outdoor units when used with iComfort Wi-Fi® Thermostat or ComfortSense® 7000 thermostat. Continuous Blower Speed - Adjustable continuous blower speed is a percentage of the high cooling speed selection. There are four selectable options (via DIP switch settings) of 28%, 38% (default setting), 70% and 100%. Accessory Terminals - Two accessory terminals furnished for additional power supply requirements for 120 volt (less than 1 amp) power humidifiers and powered air cleaners.
