BLOWER

Variable-Speed Blower Motor

High efficiency multi-speed blower motor maintains specified air volumes up to a maximum of 0.8 in. w.g. total external static.

Multi-speed operation is achieved by the use of an ECM

(Electronically Commutated

Motor) motor.

Allows cooling ramping profiles

(field selectable) for enhanced dehumidification.

Motor accelerates and decelerates gradually, reducing start-up and shut-down sound.

G

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.


FEATURES

CONTROLS

H

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 100 alarm codes with display of last 10 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 10% higher, normal or 10% 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 1 - Motor runs at 100% of capacity until demand met. Once demand is met, motor ramps down to stop.

Option 2 −

Cooling: When cool demand is initiated, motor ramps up to 100% and runs at 100% until demand is satisfied. Once demand is met, motor runs at 100% for 45 seconds, then ramps down to stop.

Heat Pump: When heat pump demand is initiated,

30 second motor on delay starts. After the motor on delays expires, motor ramps up to 100% and runs at

100% until demand is satisfied. Once demand is met, motor runs at 100% for 45 seconds, then ramps down to stop.

Option 3 - Motor runs at 82% of capacity for approximately 7.5 minutes, then 100% capacity (if needed) until demand is satisfied. Once demand is met, motor ramps down to stop.

Option 4 - Motor runs at 50% capacity for 30 seconds, then 82% capacity for approximately 7.5 minutes. If demand is not satisfied, motor runs at 100% capacity until demand is met. Once demand is met, motor runs at

50% capacity for 30 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 85 °F,

100 °F, 115°F or 130°F. Default setting is 85°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 28%, 38% (default setting), 70% and

100%.

Transformer - 70VA transformer furnished as standard.

Factory installed in the unit control box.

Accessory Terminals - Two accessory terminals are furnished for additional power supply requirements for 120 volt (less than 1 amp) power humidifiers and powered air cleaners. One 24 volt humidifier output is furnished for non-powered humidifiers.

Control board is factory installed in the unit control box.

Germicidal UVC Light

Germicidal lamp emits C-Band ultra-violet (UVC) energy at 253.7 nanometers, which is proven to be effective in reducing microbes such as viruses, bacteria, yeasts, and molds. This process either destroys the organism or controls its ability to reproduce. UVC germicidal light greatly reduces the growth and proliferation of mold and other bioaerosols (bacteria and viruses) on illuminated surfaces (particularly coil and drain pan). Surfaces must be cleaned prior to UVC light being installed.

Available in 24 volt and 110/230V-1ph models.

Air handlers have a factory provided knockout in the coil delta plate for mounting light within coil area.

Shielding baffle is required when installing light above a non-UVC resistant component, such as a filter.

Baffle must be ordered separately.
