Motor accelerates and decelerates gradually, reducing start-up and shut-down sound. Leadless blower motor features simple plug-in connections. Motor is controlled by the icomfort control that allows blower to operate at two of eight air volumes or speeds available. Speeds may be field selected on icomfort control depending on size of air handler and air volume desired. See blower performance tables. Blower Assembly Lennox designed and built, direct drive blower. Each blower is statically and dynamically balanced as an assembly before installation in the unit. Blower motor is resiliently mounted to blower assembly. Blower slides out of cabinet for servicing. CBX0UHV / Page
H FEATURES CONTROLS icomfort Control Advanced control board communicates information about various operating parameters in the air handler to the optional icomfort Wi-Fi Thermostat to constantly maintain the highest level of comfort, performance and efficiency available. Auto Configuration - On start-up the control board automatically sends a description of the unit to the optional icomfort Thermostat to automatically configure the number of stages and features available. Connections for connecting a conventional heating/ cooling thermostat are also provided on the board. Board also features: Lennox Humiditrol Whole Home Dehumidification System (EDA) compatible. EEPROM storage of all local configurations. Non-volatile memory storage of 00 alarm codes with display of last 0 codes for troubleshooting. Connections for optional outdoor temperature sensor (communicates temperature on RSBUS to thermostat). Controls evaporator humidity by controlling blower and compressor staging on two-stage outdoor units. Two stages - HEAT and COOL (with four different air volume selections for each) are made by simple jumper pins on board. ADJUST jumper pin allows approximately 0% higher, normal or 0% lower motor speed selection within HEAT and COOL speeds selected for fine tuning air volume. DELAY jumper pin allows selection of blower motor de-humidification profiles during cooling mode. Option - Motor runs at 00% of capacity until demand met. Once demand is met, motor ramps down to stop. Option - Cooling: When cool demand is initiated, motor ramps up to 00% and runs at 00% until demand is satisfied. Once demand is met, motor runs at 00% for seconds, then ramps down to stop. Heat Pump: When heat pump demand is initiated, 0 second motor on delay starts. After the motor on delays expires, motor ramps up to 00% and runs at 00% until demand is satisfied. Once demand is met, motor runs at 00% for seconds, then ramps down to stop. Option - Motor runs at 8% of capacity for approximately 7. minutes, then 00% capacity (if needed) until demand is satisfied. Once demand is met, motor ramps down to stop. Option - Motor runs at 0% capacity for 0 seconds, then 8% capacity for approximately 7. minutes. If demand is not satisfied, motor runs at 00% capacity until demand is met. Once demand is met, motor runs at 0% capacity for 0 seconds, then ramps down to stop. 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. Dehumidification (Active or Humiditrol Option) - A jumper on the control board 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. Electric Heat Operation - Control for up to three electric heat stages. EvenHeater Electric Heat Control - Up to four electric heat stages are available when utilizing the EvenHeater control feature furnished on the icomfort control. EVENHEAT jumper position on control board determines target discharge air temperature of 8 F, 00 F, F or 0 F. Default setting is 8 F. An optional Discharge Air Sensor is required. Heat Pump Operation - A jumper on the control board 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 Cooling Operation - A jumper on the control board must be clipped to enable operation with a two-stage air conditioner. 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). 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%. Transformer - 70VA transformer furnished as standard. Factory installed in the unit control box. Accessory Terminal - One volt humidifier output is furnished for non-powered humidifiers. Control board is factory installed in the unit control box. CBX0UHV / Page
