Installation is now complete.. ONFIGUING THE BLOE The variable speed high effi ciency blower kit is equipped with a microprocessor-controlled variable speed motor that is pre-programmed to deliver optimum airfl ow in a variety of conditions and system confi gurations. Before operation, the variable speed high effi ciency blower kit must be confi gured to match the unit with the system, system options, and climatic conditions. ith the variable speed high effi ciency blower kit installed and confi gured properly, the furnace will respond directly to thermostat inputs. During normal operation, the motor will gradually change speed in response to changes in the system variables, such as the thermostat settings, duct static, fi lter, etc. The variable speed high effi ciency blower kit is confi gured by setting the 8 switches located on the motor control board as described below. Note: hen used as a part of an iq Drive System, the blower airfl ow is controlled by the iq Drive thermostat, not the "HEAT" and "OOL" switches on the motor control board - these switches are ignored. However, it is necessary to set the fi rst "A/B" selector switch to select an "A" or "B" cabinet size, if applicable(see section "Selecting the abinet Size"). Also see iq Drive instructions.
IMPOTANT The variable speed high efficiency blower kit is designed to give the installer maximum flexibility to optimize system performance, efficiency, and comfort. Because there are so many way to configure the kit, it is important to read and follow these instructions carefully. Selecting the abinet Size The furnace cabinet size may be selected by setting the fi rst switch marked "A/B". For an A-size furnace, this switch should be set to 0 or "off". For a B-size furnace, this switch should be set to or "on". For a - or D-size furnace, the switch setting does not matter - it may be set to either "on" or "off". Selecting the (Gas) Heating Airfl ow The heating airfl ow is selected by setting switches through (also marked as HEAT) on the motor control board. efer to the Airfl ow Settings graph and select an airfl ow to allow the furnace to reach an appropriate heat rise as shown on the unit rating plate. To reduce the heat rise, select a higher airfl ow; to increase the heat rise, select a lower airfl ow. Be sure that the selected rise is within the specifi cation of the furnace as shown on the furnace rating label. Determining Nominal System apacity (A/ & HP) In order to select the appropriate airfl ow for the A and HP operation, the nominal system capacity must be known. The nominal system capacity is ALAYS the nominal capacity of the outdoor unit. In some cases, the nominal system capacity is not the same as the nominal capacity of the indoor coil. Selecting the ooling/heat Pump Airfl ow The cooling/heat pump airfl ow is selected by setting switches through 8 (also marked as OOL) on the motor control board. All airfl ows for other modes of operation, except for gas heat, are determined by this setting. efer to the Airfl ow Settings graph and select an airfl ow in the range recommended for the nominal system capacity. For maximum capacity and energy effi ciency, generally a selection at or near the top of the FM range for that nominal system capacity is best. For maximum dehumidifi cation, select an airfl ow near the middle or bottom of the FM range for that nominal system capacity. Note: If coil icing is observed, the cooling/heat pump airfl ow may be set too low. Double-check to be sure the setting selected is within the range shown. Also, check to be sure the system is properly charged (see outdoor unit installation instructions). If icing continues to occur, raise the selected airfl ow one or two steps.. SYSTEM OPEATION (Gas) Heating Mode hen the thermostat calls for heating, the circuit between and is completed. The furnace control board initiates the ignition sequence. Approximately 0 seconds after the gas fl ame has proven, the blower motor will slowly ramp up to the selected motor airfl ow. The blower will continue to operate after the call for heat has been removed for a selectable (switch on furnace control board) number of seconds. Note: All on- and off-delays for heating continue to be controlled by the furnace control board. ooling or Heat Pump Mode hen the thermostat calls for cooling or heat pump heating, the circuit between, G, and Y (O is ignored by the blower) is completed. The blower slowly ramps up to the selected cooling airfl ow. If there is a humidistat connected to the motor control board calling for humidity control, the motor will operate at 7% of the airfl ow setting. Or, if the system is installed where humidity control is desired but a humidistat is not available, the DEHUM and terminals on the motor control board may be jumpered. In this case, the blower will operate at 7% airfl ow for the fi rst 0 minutes of the cycle and then return to normal torque for the remainder of the cooling cycle. After the call for cooling or heat pump is satisfi ed, the blower continues to operate for 0 seconds at 0% of the selected airfl ow. Manual Fan hen the manual fan switch on the thermostat is on, energizing G only, the blower will ramp up to 0% of the selected cooling/heat pump motor airfl ow..
