Electrostatic Discharge (ESD) Precautions
NOTE: Discharge body’s stac electricity before touching unit. An
electrostac discharge can adversely aect electrical components.
Use the following precauons during modular blower installaon
and servicing to protect the integrated control module from dam-
age. By pung the modular blower, the control, and the person
at the same electrostac potenal, these steps will help avoid
exposing the integrated control module to electrostac discharge.
This procedure is applicable to both installed and uninstalled (un-
grounded) blowers.
1. Disconnect all power to the blower. Do not touch the
integrated control module or any wire connected to the
control prior to discharging your body’s electrostac charge
to ground.
2. Firmly touch a clean, unpainted, metal surface of the
modular blower near the control. Any tools held in a
person’s hand during grounding will be discharged.
3. Service integrated control module or connecng wiring
following the discharge process in step 2. Use cauon not
to recharge your body with stac electricity; (i.e., do not
move or shue your feet, do not touch ungrounded objects,
etc.). If you come in contact with an ungrounded object,
repeat step 2 before touching control or wires.
4. Discharge your body to ground before removing a new
control from its container. Follow steps 1 through 3 if
installing the control on a blower. Return any old or new
controls to their containers before touching any ungrounded
object.

General Information
The MBVC Blower Cabinets are used in combinaon with a cased
evaporator coil. This combinaon of blower and coil funcons
as the indoor part of a split air-condioning system, and may be
matched with a remote condensing or heat pump unit. The blower
cabinet can also funcon as an electric furnace when used with an
electric heater.
NOTE: The electric heating elements for electric furnace
installaon are not shipped with the cabinet and are eld-installed.
Systems should be properly sized by heat gain and loss calculaons
made according to methods of the Air Condioning Contractors
Associaon (ACCA) or equivalent. It is the contractor’s responsi-
bility to ensure the system has adequate capacity to heat or cool
the condioned space.
Features
This modular blower is a part of the ComfortBridge™ Technology
family of products. The Modular Blower can operate as a digitally
communicang system requiring only simple 24VAC thermostat in-
puts to funcon (Y for cooling, W for heang, G for fan operaons).
Internal algorithms will provide 2 stage or inverter Air Condioner
or Heat Pump funconality based on these simple inputs. With
built-in Bluetooth operaon, the CoolCloud™ HVAC phone appli-
caon is available for commissioning, soware and shared data
updates and troubleshoong. The Modular Blower can support
non-communicang outdoor unit installaons as well. See wiring
secons for more details. The ComfortBridge™ Technology system
simplies wiring, provides enhanced setup features and elevates
diagnoscs capabilies.
Achieving Less Air Leakage:
Ensure all the gaskets remain intact on surfaces as shipped with the
unit. Ensure upon installaon that the plasc breaker cover is ush
on with the access panel and access panel is ush with the cabinet.
With these requirements sased, the unit achieves less airow
leakage when tested in accordance with ASHRE Standard 193.
• Cabinet air leakage less than 2.0% at 1.0 inch H
2
O when
tested in accordance with ASHRAE standard 193.
• Cabinet air leakage less than 1.4% at 0.5 inch H
2
O when
tested in accordance with ASHRAE standard 193.
Clearances And Accessibility
The unit can be posioned for upow, counterow, horizontal right
or horizontal le operaon. Zero clearance is allowed on all sides
for combusble materials. Thirty-six inches should be alloed on
the door side for maintenance and service.
To reduce risk of rusng, do not install the unit directly on the
ground or on a oor that is likely to be wet. In such environments,
the unit must be elevated by use of a sturdy, nonporous material.
Insulation
To ensure ecient operaon, review the following precauons.
• If the unit is located in an area with high ambient
temperature and/or high humidity, the air handler may
be subject to nuisance sweang of the casing. On these
installaons, a wrap of 2” berglass insulaon with a vapor

Quick Start Guide for Communicating Outdoor Units
EXTREMELY IMPORTANT: For all cooling calls the system only re-
quires a single Y input from the thermostat. For all heang calls
(including applicaons with backup electric heater kits) the system
only requires a single W input from the thermostat. Internal algo-
rithms will control all available cooling and heang stages based
on these inputs. Any single-stage 24VAC thermostat can be used.
For proper operaon, the thermostat must be setup to control a
single stage AC outdoor unit and to control single stage electric
heat operaon. The control board does not accommodate an O
wire thermostat input (reversing valve signal). If a heat pump is
installed, the thermostat should be setup as stated above. Seng
the thermostat for the heat pump control or mulstage control
may result in incorrect performance.
1. Connect all necessary thermostat wires to the thermostat
connector on the air handler control as instructed by the
applicable wiring diagrams shown in this secon.
2. Connect the 1 & 2 wires between the indoor and outdoor
unit for communicang operaon.
Note: Verify two stage outdoor units include a 24VAC
transformer (for outdoor control board power). Two stage
outdoor units may not behave properly without this 24 VAC
transformer.

with equipment.
Dehumidification
Dehumidicaon allows the air handler’s circulator blower to
operate at a reduced speed during a combined thermostat call
for cooling and a dehumidicaon call from the thermostat or
humidistat. This lower blower speed increases dehumidicaon
of the condioned air as it passes through the indoor coil. The
control board is equipped with a 24 volt dehumidicaon input
(DH) located on the thermostat wiring connector. The terminal
can be congured to enable dehumidicaon when the input is
energized or de-energized. When using an external dehumidistat,
connect it between the R and DH terminals. If the humidistat
closes on humidity rise or the thermostat energizes this terminal
when dehumidicaon is required, set the control board Dehum
Logic Menu (dL) to “I” using the push buons or CoolCloud
HVAC phone applicaon. If the humidistat opens on humidity or
the thermostat de-energizes this terminal when dehumidicaon
is required, set the Dehum Logic Menu to “L” using the push
buons or CoolCloud HVAC phone applicaon.

Auxiliary Alarm Switch
The control is equipped with a 24VAC Aux Alarm to be used for
a condensate switch install (designated by CONDENSATE IN/OUT
on the control). By default, the connected AUX switch is normally
closed and opens when the water level in the evaporator coil base
pan reaches an undesirable level. The control responds by display-
ing a “” error code and turning o the outdoor condensing
unit. If the AUX switch is detected to be in the closed posion for
30 seconds, normal operaon resumes and the error message is
no longer displayed.
7-Segment Display and Push Buttons
Figure 14
The air handler includes three on-board push buons allowing
users to navigate indoor and outdoor system menus. The Right
and Le buons allow the user to scroll through the main menus
and to then scroll through available opons within specic menus.
The Center buon is used to enter into a main menu and to then
permanently select opons within those menus.
NOTE: Aer scrolling to the desired opon within a menu, that
opon may be ashing on the 7-segment displays. This indicates
the opon has not been ocially selected. Pressing the Center
buon two mes will select that opon. The rst press will stop
the ashing. The second will make the selecon ocial and return
you to the main menu.
Accessory Control (Humidifiers, Dehumidifiers,
Ventilators)
If an external humidier, dehumidier or venlator is installed, it
may require airow from the HVAC system to funcon properly.
1. Make sure the installed 24 VAC thermostat is capable of
controlling the accessory or accessories.
2. Connect the appropriate accessory control wires to the
accessory devices from the thermostat (see thermostat
manual for connecon and setup instrucons).
3. If the thermostat is capable of providing a connuous fan
call (G signal) during accessory operaon: Make sure to
connect the thermostat G terminal to the G terminal on the
indoor unit. Setup thermostat to ensure G signal is energized
during accessory operaon.
Figure 15
4. Select the appropriate fan only airow for the accessory
using the indoor unit push buon menus or the CoolCloud
HVAC phone applicaon.
5. Using the thermostat, independently test each accessory in
addion to the independently tesng connuous fan mode.
Ramping Profiles
The variable-speed circulator oers four dierent ramping proles.
These proles may be used to enhance cooling performance and
increase comfort level. Select the desired ramping prole using the
CoolCloud phone applicaon or the push buon menus.
When used with communicang outdoor units the cooling prole
must be selected in the outdoor unit menus.
When used with non-communicang outdoor units the cooling
proles must be selected in the indoor unit menus.

Troubleshooting
Electrostatic Discharge (ESD) Precautions
NOTE: Discharge body’s stac electricity before touching unit. An
electrostac discharge can adversely aect electrical components.
Use the following precauons during modular blower installaon
and servicing to protect the integrated control module from dam-
age. By pung the modular blower, the control, and the person
at the same electrostac potenal, these steps will help avoid
exposing the integrated control module to electrostac discharge.
This procedure is applicable to both installed and uninstalled (un-
grounded) blowers.
1. Disconnect all power to the blower. Do not touch the
integrated control module or any wire connected to the
control prior to discharging your body’s electrostac charge
to ground.
2. Firmly touch a clean, unpainted, metal surface of the
modular blower near the control. Any tools held in a
person’s hand during grounding will be discharged.
3. Service integrated control module or connecng wiring
following the discharge process in step 2. Use cauon not
to recharge your body with stac electricity; (i.e., do not
move or shue your feet, do not touch ungrounded objects,
etc.). If you come in contact with an ungrounded object,
repeat step 2 before touching control or wires.
4. Discharge your body to ground before removing a new
control from its container. Follow steps 1 through 3 if
installing the control on a blower. Return any old or new
controls to their containers before touching any ungrounded
object.
Figure 16
Electric Air Cleaner
The control is equipped with an Accessory Relay and a pair of ¼ inch
accessory terminals which is normally open, labeled EAC-IN and
EAC-OUT (see accessory contacts graphic). The Accessory Relay is
congured to close anyme the blower is running. A closed relay
means the two terminals will have connuity between them (the
control does not energize these contacts). It is recommended to
ulize 24VAC with these terminals and limit the current to 1A.

AIR HANDLER
AIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed
before the heang and cooling seasons begin by a qualied servicer.
REPLACE OR CLEAN FILTER
IMPORTANT NOTE: Never operate unit without a lter installed
as dust and lint will build up on internal parts resulng in loss of
eciency, equipment damage and possible re.
An indoor air lter must be used with your comfort system. A
properly maintained lter will keep the indoor coil of your comfort
system clean. A dirty coil could cause poor operaon and/or severe
equipment damage.
Your air lter or lters could be located in your furnace, in a blower
unit, or in “lter grilles” in your ceiling or walls. The installer of your
air condioner or heat pump can tell you where your lter(s) are,
and how to clean or replace them.
Check your lter(s) at least once a month. When they are dirty,
replace or clean as required. Disposable type lters should be
replaced. Reusable type lters may be cleaned.
You may want to ask your dealer about high eciency lters. High
eciency lters are available in both electronic and non-electronic
types. These lters can do a beer job of catching small airborne
parcles.
MOTORS
Indoor and outdoor fan motors are permanently lubricated and do
not require addional oiling.
ALUMINUM INDOOR COIL CLEANING
(QUALIFIED SERVICER ONLY)
This unit is equipped with an aluminum tube evaporator coil. The
safest way to clean the evaporator coil is to simply ush the coil
with water. This cleaning pracce remains as the recommended
cleaning method for both copper tube and aluminum tube resi-
denal evaporator coils.
It has been determined that many coil cleaners and drain pan tab-
lets contain corrosive chemicals that can be harmful to aluminum
tube and n evaporator coils. Even a one-me applicaon of these
corrosive chemicals can cause premature aluminum evaporator coil
failure. Any cleaners that contain corrosive chemicals including,
but not limited to, chlorine and hydroxides, should not be used.
An alternate cleaning method is to use one of the products listed in
TP-109* to clean the coils. The cleaners listed are the only agents
deemed safe and approved for use to clean round tube aluminum
coils. TP-109 is also available on the web site in Partner Link >
Service Toolkit.
NOTE: Ensure coils are rinsed well aer use of any chemical cleaners.
BEFORE YOU CALL YOUR SERVICER
• Check the thermostat to conrm that it is properly set.
• Wait 15 minutes. Some devices in the outdoor unit or
in programmable thermostats will prevent compressor
operaon for awhile, and then reset automacally. Also,
some power companies will install devices which shut o
air condioners for several minutes on hot days. If you wait
several minutes, the unit may begin operaon on its own.
• Check the electrical panel for tripped circuit breakers or
failed fuses. Reset the circuit breakers or replace fuses as
necessary.
• Check the disconnect switch near the indoor furnace or
blower to conrm that it is closed.
• Check for obstrucons on the outdoor unit . Conrm that
it has not been covered on the sides or the top. Remove
any obstrucon that can be safely removed. If the unit is
covered with dirt or debris, call a qualied servicer to clean
it.
• Check for blockage of the indoor air inlets and outlets.
Conrm that they are open and have not been blocked by
objects (rugs, curtains or furniture).
• Check the lter. If it is dirty, clean or replace it.
• Listen for any unusual noise(s), other than normal operang
noise, that might be coming from the outdoor unit. If you
hear unusual noise(s) coming from the unit, call a qualied
servicer.
