GENERAL INFORMATION  
COMFORTNET™ SYSTEM  
The MBVC Blower Cabinets are used in combination with a  
cased evaporator coil for a two-piece blower and coil combi-  
nation. This combination of blower and coil functions as the  
indoor part of a split air-conditioning system, and may be  
matched with a remote condensing or heat pump unit and  
allows for a variety of mix-matching possibilities.  
OVERVIEW  
The ComfortNet™ system (or CT™ system) is a system that  
includes a ComfortNet™ compatible modular blower and air  
conditioner or heat pump with a CTK01AA thermostat. Any  
other system configurations are considered invalid  
ComfortNet™ systems and must be connected as a tradi-  
tional (or legacy) system. The table below compares the  
valid CT™ systems.  
The blower cabinet can also function as an electric furnace  
when used with an electric heater.

NOTE: The electric heating elements for electric furnace

accessories for supplemental electric heat.

benefits & features  
Systems should be properly sized by heat gain and loss  
calculations made according to methods of the Air Condi-  
tioning Contractors Association (ACCA) or equivalent. It is  
the contractor’s responsibility to ensure the system has ad-  
equate capacity to heat or cool the conditioned space.  
A ComfortNet™ heating/air conditioning system differs from  
a legacy/traditional system in the manner in which the indoor  
unit, outdoor unit and thermostat interact with one another.  
In a traditional system, the thermostat sends commands to  
the indoor and outdoor units via analog 24 VAC signals. It is  
a one-way communication path in that the indoor and out-  
door units typically do not return information to the thermo-  
stat.  
The MBVC blower cabinet uses a variable speed motor that  
maintains a constant airflow with a higher duct static. It is  
approved for applications with cooling coils of up to 0.8 inches  
W.C. external static pressure and includes a feature that On the other hand, the indoor unit, outdoor unit, and thermo-  
allows airflow to be changed to + 10%.  
stat comprising a ComfortNet™ system “communicate” digi-  
tally with one another. It is now a two-way communications  
path. The thermostat still sends commands to the indoor  
and outdoor units. However, the thermostat may also re-  
quest and receive information from both the indoor and out-  
door units. This information may be displayed on the CT™  
thermostat. The indoor and outdoor units also interact with  
one another. The outdoor unit may send commands to or  
request information from the indoor unit. This two-way digital  
communications between the thermostat and subsystems  
(indoor/outdoor unit) and between subsystems is the key to  
unlocking the benefits and features of the ComfortNet™ sys-  
tem.  
The MBVC blower cabinets, with proper coil matches, can  
be positioned for upflow, counterflow, horizontal right or hori-  
zontal left operation. All units are constructed with R-4.2  
insulation. In areas of extreme humidity (greater than 80%  
consistently), insulate the exterior of the blower with insula-  
tion having a vapor barrier equivalent to ductwork insulation,  
providing local codes permit.  
The CAPX/CHPX coils are equipped with a thermostatic ex-  
pansion valve that has a built-in internal check valve for refrig-  
erant metering. The CACF/CAPF/CHPF coils are equipped  
with a fixed restrictor orifice.  
Two-way digital communications is accomplished using only  
two wires. The thermostat and subsystem controls are pow-  
ered with 24 VAC Thus, a maximum of 4 wires between the  
equipment and thermostat is all that is required to operate  
the system.  
The coils are designed for upflow, counterflow, or horizontal  
application, using ECM motors on the MBVC models.  
FEATURES  
This modular blower is a part of the ComfortNet™ family of  
products. It may be installed as part of a “legacy” system  
using a standard 24 VAC thermostat. However, with the  
CTK01AA ComfortNet™ thermostat kit, this modular blower  
may be installed as part of a digitally communicating sys-  
tem. The ComfortNet™ system provides automatic airflow  
configuration, enhanced setup features, and enhanced diag-  
nostics. It also reduces the number of thermostat wires to a  
maximum of four.
