ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
NOTE: Discharge body’s static electricity before touching unit. Anelectrostatic discharge can adversely affect electrical components.
Use the following precautions during modular blower installationand servicing to protect the integrated control module from dam-age. By putting the modular blower, the control, and the personat the same electrostatic potential, these steps will help avoid ex-posing the integrated control module to electrostatic discharge.This procedure is applicable to both installed and uninstalled (un-grounded) blowers.
1. Disconnect all power to the blower. Do not touch theintegrated control module or any wire connected to thecontrol prior to discharging your body’s electrostatic chargeto ground.
2. Firmly touch a clean, unpainted, metal surface of themodular blower near the control. Any tools held in aperson’s hand during grounding will be discharged.
3. Service integrated control module or connecting wiringfollowing the discharge process in step 2. Use caution notto recharge your body with static electricity; (i.e., do notmove or shuffle your feet, do not touch ungroundedobjects, etc.). If you come in contact with an ungroundedobject, repeat step 2 before touching control or wires.
4. Discharge your body to ground before removing a newcontrol from its container. Follow steps 1 through 3 ifinstalling the control on a blower. Return any old or newcontrols to their containers before touching anyungrounded object.

GENERAL INFORMATION
The MBVC Blower Cabinets are used in combination with a casedevaporator coil. This combination of blower and coil functions asthe indoor part of a split air-conditioning system, and may bematched with a remote condensing or heat pump unit. The blowercabinet can also function as an electric furnace when used withan electric heater.
NOTE: The electric heating elements for electric furnaceinstallation are not shipped with the cabinet and are field-installed.
Systems should be properly sized by heat gain and loss calcula-tions made according to methods of the Air Conditioning Contrac-tors Association (ACCA) or equivalent. It is the contractor’s re-sponsibility to ensure the system has adequate capacity to heat orcool the conditioned space.
FEATURES
This modular blower is a part of the ComfortNet™ family of prod-ucts. It may be installed as part of a “legacy” system using a stan-dard 24 VAC thermostat or, with a ComfortNet™ thermostat kit,as part of a digitally communicating system. The ComfortNet™system simplifies wiring, provides enhanced setup features andelevates diagnostics capabilities.

24 VOLT “LEGACY” THERMOSTAT WIRING
NOTE: Wire routing must not interfere with the circulator bloweroperation or routine maintenance.
The optional usage of a dehumidistat allows the modular blower’scirculator blower to operate at a slightly lower speed during a com-bined thermostat call for cooling and dehumidistat call for dehu-midification. This lower blower speed enhances dehumidificationof the conditioned air as it passes through the AC coil. For properfunction, a dehumidistat applied to this modular blower must op-erate on 24 VAC and utilize a switch which opens on humidity rise.To install/connect a dehumidistat:1. Turn OFF power to modular blower2. Secure the dehumidistat neutral wire (typically the white
lead) to the screw terminal marked “DEHUM” on themodular blower’s integrated control module.
3. Secure the dehumidistat hot wire (typically the black lead)to the screw terminal marked “R” on the modular blower’sintegrated control module.
4. Secure the dehumidistat ground wire (typically the greenlead) to the ground screw on the modular blower. NOTE:Ground wire may not be present on all dehumidistats.
5. Turn ON power to modular blower.

AUXILIARY ALARM SWITCH
The control is equipped with two Auxiliary Alarm terminals labeledCAS which can be utilized with communicating mode setups (typi-cally used for condensate switch wiring but could be used withcompatible C02 sensors or fire alarms).Legacy mode useIn a legacy system (Non-communicating), this feature is not op-erational. Any auxiliary alarm switch must be used to interruptthe Y1 signal either to the indoor or outdoor unit.Communication mode useThis feature can be activated or deactivated through the thermo-stat user menus. An auxiliary alarm switch must be normally closedand open when the base pan’s water level in the evaporator coilreaches a particular level. The control will respond by turning offthe outdoor compressor and display the proper fault codes. If theswitch is detected closed for 30 seconds, normal operation re-sumes and the error message will be removed.

This modular blower is equipped with a variable speed circulatorblower. This blower provides ease in adjusting blower speeds.The Specification Sheet applicable to your model provides an air-flow table, showing the relationship between airflow (CFM) andexternal static pressure (E.S.P.), for the proper selection of heat-ing and cooling speeds. The heating blower speed is shipped setat “21 kW”, and the cooling blower speed is set at “D”. Theseblower speeds should be adjusted by the installer to match theinstallation requirements so as to provide the correct electric heat-ing CFM and correct cooling CFM.Use the CFM LED (green) to obtain an approximate airflow quan-tity. The green CFM LED blinks once for each 100 CFM of airflow.1. Determine the tonnage of the cooling system installed with
the modular blower. If the cooling capacity is in BTU/hrdivide it by 12,000 to convert capacity to TONs.Example: Cooling Capacity of 30,000 BTU/hr.30,000/12,000 = 2.5 Tons
2. Determine the proper air flow for the cooling system. Mostcooling systems are designed to work with air flowsbetween 350 and 450 CFM per ton. Most manufacturersrecommend an air flow of about 400 CFM per ton.Example: 2.5 tons X 400 CFM per ton = 1000 CFM

The cooling system manufacturer’s instructions must be checkedfor required air flow. Any electronic air cleaners or other devicesmay require a specific airflow; consult installation instructions ofthose devices for requirements.3. Knowing the modular blower model, locate the high stage
cooling air flow charts in the Specification Sheet applicableto your model. Look up the cooling air flow determined instep 2 and find the required cooling speed and adjustmentsetting.Example: A MBVC1200 modular blower installed with a2.5 ton air conditioning system. The air flow needed is 1000CFM. Looking at the cooling speed chart for MBVC1200,find the air flow closest to 1000 CFM. A cooling airflow of1000 CFM can be attained by setting the cooling speed to“C” and the adjustment to “Normal” (no adjustment).
4. Locate the blower speed selection DIP switches on theintegrated control module. Select the desired “cooling”speed tap by positioning switches 1 and 2 appropriately. Ifairflow adjustment is required, set dip switch S8 (trimenable) to ON (trim enable default is off). Then select thedesired “adjust” tap by positioning switches S3 and S4appropriately. Refer to the following figure for switchpositions and their corresponding taps. Verify CFM bycounting the number of times the green CFM LED blinks.
5. Continuous fan speeds that provide 25, 50, 75, and 100%of the furnace’s maximum airflow capability are selectablevia dip switches S12 and S13.If the furnace’s maximum airflow capability is 2000 CFMand 25% continuous fan spped is selected, the continuousfan speed will be 0.25 x 2000 CFM = 500 CFM.
6. The multi-speed circulator blower also offers several customON/OFF ramping profiles. These profiles may be used toenhance cooling performance and increase comfort level.
The ramping profiles are selected using DIP switches 5 and6. Refer to Figure 14 for switch positions and theircorresponding taps. Refer to the bullet points below for adescription of each ramping profile. Verify profile selectionby counting the green CFM LED blinks and timing each stepof the ramping profile.

COMFORTNET™ SYSTEM
OVERVIEW
The ComfortNet™ system (or CT™ system) is a system that includesa ComfortNet™ compatible modular blower and air conditioner orheat pump with a CTK04 thermostat. Any other system configura-tions are considered invalid ComfortNet™ systems and must beconnected as a traditional (or legacy) system (see Electrical Con-nections - 24 Volt Thermostat Wiring for wiring connections).A ComfortNet™ heating/air conditioning system differs from alegacy/traditional system in the manner in which the indoor unit,outdoor unit and thermostat interact with one another. In a tradi-tional system, the thermostat sends commands to the indoor andoutdoor units via analog 24 VAC signals. It is a one-way communi-cation path in that the indoor and outdoor units typically do notreturn information to the thermostat.In a ComfortNetTM system, the indoor unit, outdoor unit, andthermostat “communicate” digitally with one anothercreating a two-way communications path. The thermostatsends commands to the indoor and outdoor units, and alsorequests and receives information from both the indoor andoutdoor units.
Two-way digital communications is accomplished using only twowires. The thermostat and subsystem controls are powered with24 VAC Thus, a maximum of 4 wires between the equipment andthermostat is all that is required to operate the system.
AIRFLOW CONSIDERATION
Airflow demands are managed differently in a fully communicat-ing system than they are in a legacy wired system. The systemoperating mode (as determined by the thermostat) determineswhich unit calculates the system airflow demand. If the indoorunit is responsible for determining the airflow demand, it calcu-lates the demand and sends it to the ECM motor. If the outdoorunit or thermostat is responsible for determining the demand, itcalculates the demand and transmits the demand along with afan request to the indoor unit. The indoor unit then sends thedemand to the ECM motor. Figure 21 lists the variousComfortNet™ systems, the operating mode, and airflow demandsource.
TROUBLESHOOTING
ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
NOTE: Discharge body’s static electricity before touching unit. Anelectrostatic discharge can adversely affect electrical components.
Use the following precautions during modular blower installationand servicing to protect the integrated control module from dam-age. By putting the modular blower, the control, and the personat the same electrostatic potential, these steps will help avoid ex-posing the integrated control module to electrostatic discharge.This procedure is applicable to both installed and uninstalled (un-grounded) blowers.
1. Disconnect all power to the blower. Do not touch theintegrated control module or any wire connected to thecontrol prior to discharging your body’s electrostatic chargeto ground.
2. Firmly touch a clean, unpainted, metal surface of themodular blower near the control. Any tools held in aperson’s hand during grounding will be discharged.
3. Service integrated control module or connecting wiringfollowing the discharge process in step 2. Use caution notto recharge your body with static electricity; (i.e., do notmove or shuffle your feet, do not touch ungroundedobjects, etc.). If you come in contact with an ungroundedobject, repeat step 2 before touching control or wires.
4. Discharge your body to ground before removing a newcontrol from its container. Follow steps 1 through 3 ifinstalling the control on a blower. Return any old or newcontrols to their containers before touching anyungrounded object.
DIAGNOSTIC CHART
Refer to the Troubleshooting Chart at the end of this manual forassistance in determining the source of unit operational problems.The 7 segment LED display will provide any active fault codes. Anarrow printed next to the display indicates proper orientation (ar-row points to top of display). See following image.
HIGH VOLTAGE!TO AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK, DISCONNECT ELECTRICAL POWER BEFORE PERFORMING ANY SERVICE OR MAINTENANCE.

medium, or high continuous fan speed. The low, medium, andhigh fan speeds correspond to 25%, 50%, and 75%, respectively,of the air handlers’ maximum airflow capability. During continu-ous fan operation, the thermostat sends a fan request along withthe continuous fan demand to the air handler. The air handler, inturn, sends the demand to the ECM motor. The ECM motor deliv-ers the requested continuous fan airflow.
CONTROL WIRING
NOTE: Refer to section Electrical Connections for 208/230 voltline connections to the modular blower.
NOTE: A removable plug connector is provided with the control tomake thermostat wire connections. This plug may be removed,wire connections made to the plug, and replaced. It is STRONGLYrecommended that you do no connect multiple wires into a singleterminal. Wire nuts are recommended to ensure one wire is usedfor each terminal.
Typical 18 AWG thermostat wire may be used to wire the systemcomponents. 150 feet is the maximum recommended length ofwire recommended between indoor and outdoor unit, or betweenindoor unit and thermostat.Only data lines 1 and 2 are required between the indoor and out-door units. The included 40VA, 208/230 VAC to 24 VAC transformermust be installed in the outdoor unit to provide 24 VAC power tothe outdoor unit’s electronic control. See kit instructions for mount-ing and wiring instructions.

COMFORTNET™ SYSTEM ADVANCED FEATURES
The ComfortNet™ system permits access to additional system in-formation, advanced setup features, and advanced diagnostic/troubleshooting features. These advanced features are organizedinto a menu structure. See the following MODULAR BLOWER AD-VANCED FEATURES MENUS section for layout of menu shortcuts.

Figure 21 - Airflow Demands
For example, assume the system is a heat pump matched with anair handler. With a call for low stage cooling, the heat pump willcalculate the system’s low stage cooling airflow demand. The heatpump will then send a fan request along with the low stage cool-ing airflow demand to the air handler. Once received, the air han-dler will send the low stage cooling airflow demand to the ECMmotor. The ECM motor then delivers the low stage cooling air-flow. See the applicable ComfortNet™ air conditioner or heat pumpinstallation manual for the airflow delivered during cooling or heatpump heating.In continuous fan mode, the CTK0* thermostat provides the air-flow demand. The thermostat may be configured for a low, me-dium, or high continuous fan speed. The low, medium, and highfan speeds correspond to 25%, 50%, and 75%, respectively, of theair handlers’ maximum airflow capability. During continuous fanoperation, the thermostat sends a fan request along with the con-tinuous fan demand to the air handler. The air handler, in turn,sends the demand to the ECM motor. The ECM motor deliversthe requested continuous fan airflow.

DIAGNOSTICS
Accessing the modular blower’s diagnostics menu provides readyaccess to the last six faults detected by the modular blower. Faultsare stored most recent to least recent. Any consecutively repeatedfault is stored a maximum of three times. Example: A cloggedreturn air filter causes the modular blower’s motor to repeatedlyenter a limiting condition. The control will only store this fault thefirst three consecutive times the fault occurs.
NOTE: It is highly recommended that the fault history be clearedwhen performing maintenance or servicing the modular blower.
NETWORK TROUBLESHOOTING
The ComfortNet™ system is a fully communicating system, andthus, constitutes a network. Occasionally the need to trouble-shoot the network may arise. The integrated control has someon-board tools that may be used to troubleshoot the network.
These tools are: red communications LED, green receive (Rx) LED,and LEARN button.
• Red communications LED – Indicates the status of thenetwork. The table below indicates the LED status andthe corresponding potential problem.
• Green receive LED – Indicates network traffic. The tablebelow indicates the LED status and the correspondingpotential problem.
• Learn button – Used to reset the network. Depress thebutton for approximately 2 seconds to reset the network.

AIR HANDLERAIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performedbefore the heating and cooling seasons begin by a qualified servicer.
REPLACE OR CLEAN FILTER
IMPORTANT NOTE: Never operate unit without a filter installedas dust and lint will build up on internal parts resulting in loss ofefficiency, equipment damage and possible fire.An indoor air filter must be used with your comfort system. Aproperly maintained filter will keep the indoor coil of your com-fort system clean. A dirty coil could cause poor operation and/orsevere equipment damage.Your air filter or filters could be located in your furnace, in a blowerunit, or in “filter grilles” in your ceiling or walls. The installer ofyour air conditioner or heat pump can tell you where your filter(s)are, and how to clean or replace them.Check your filter(s) at least once a month. When they are dirty,replace or clean as required. Disposable type filters should bereplaced. Reusable type filters may be cleaned.You may want to ask your dealer about high efficiency filters. Highefficiency filters are available in both electronic and non-electronictypes. These filters can do a better job of catching small airborneparticles.
MOTORS
Indoor and outdoor fan motors are permanently lubricated anddo not require additional oiling.
ALUMINUM INDOOR COIL CLEANING(QUALIFIED SERVICER ONLY)This unit is equipped with an aluminum tube evaporator coil. Thesafest way to clean the evaporator coil is to simply flush the coilwith water. This cleaning practice remains as the recommendedcleaning method for both copper tube and aluminum tube resi-dential evaporator coils.It has been determined that many coil cleaners and drain pantablets contain corrosive chemicals that can be harmful to alumi-num tube and fin evaporator coils. Even a one-time applicationof these corrosive chemicals can cause premature aluminumevaporator coil failure. Any cleaners that contain corrosive chemi-cals including, but not limited to, chlorine and hydroxides, shouldnot be used.
An alternate cleaning method is to use one of the products listedin TP-109* to clean the coils. The cleaners listed are the only agentsdeemed safe and approved for use to clean round tube aluminumcoils. TP-109 is also available on the web site in Partner Link >Service Toolkit.NOTE: Ensure coils are rinsed well after use of any chemical clean-ers.
BEFORE YOU CALL YOUR SERVICER• Check the thermostat to confirm that it is properly set.• Wait 15 minutes. Some devices in the outdoor unit or in
programmable thermostats will prevent compressoroperation for awhile, and then reset automatically. Also,some power companies will install devices which shut offair conditioners for several minutes on hot days. If you waitseveral minutes, the unit may begin operation on its own.
• Check the electrical panel for tripped circuit breakers orfailed fuses. Reset the circuit breakers or replace fuses asnecessary.
• Check the disconnect switch near the indoor furnace orblower to confirm that it is closed.
• Check for obstructions on the outdoor unit . Confirm that ithas not been covered on the sides or the top. Remove anyobstruction that can be safely removed. If the unit iscovered with dirt or debris, call a qualified servicer to cleanit.
• Check for blockage of the indoor air inlets and outlets.Confirm that they are open and have not been blocked byobjects (rugs, curtains or furniture).
• Check the filter. If it is dirty, clean or replace it.• Listen for any unusual noise(s), other than normal operating
noise, that might be coming from the outdoor unit. If youhear unusual noise(s) coming from the unit, call a qualifiedservicer.
