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 which allows custom blower settings based on the application. EL96DFV / Page 4

5 FEATURES CONTROLS (continued) 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 control 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. DIP Switch Settings 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 Speeds - 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. Cooling Speeds - 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 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 0 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 0 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 (single stage units or two-stage units running at nd stage). 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/Off Time (Heating) - Blower on time is fixed at 0 seconds, blower off time is adjustable from 60, 90, 0 and 80 seconds (factory setting - 90 seconds). Blower On/Off Time (Cooling) - For air-conditioning applications, blower on time is seconds following thermostat demand for cooling. See Blower Speed Ramping (Cooling 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. EL96DFV / Page 5

6 FEATURES CONTROLS (continued) 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 8%, 8% (default setting), 70% and 00%.
