NFORMATION
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.

The blower cabinet can also function as an electric furnace

NOTE: The electric heating elements for electric furnace
installation are not shipped with the cabinet and are field-
installed. Electric heater kits (HKR) are available as sales
accessories for supplemental electric heat.

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
allows airflow to be changed to + 10%.

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.

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.

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.

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.

On the other hand, the indoor unit, outdoor unit, and thermo-
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.

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.
