ENERAL INFORMATION

OMFORTNET SYSTEM

The MBVC Blower Cabinets are used in combination with a cased evaporator coil for a two-piece blower and coil combination. 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 when used with an electric heater.

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

Systems should be properly sized by heat gain and loss calculations made according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent. It is the contractor’s responsibility to ensure the system has adequate capacity to heat or cool the conditioned space.

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 horizontal 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 insulation having a vapor barrier equivalent to ductwork insulation, providing local codes permit.

The CAPX/CHPX coils are equipped with a thermostatic expansion valve that has a built-in internal check valve for refrigerant metering. The CACF/CAPF/CHPF coils are equipped with a fixed restrictor orifice.

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 CTK0*AA ComfortNet thermostat kit, this modular blower may be installed as part of a digitally communicating system. The ComfortNet system provides automatic airflow configuration, enhanced setup features, and enhanced diagnostics. It also reduces the number of thermostat wires to a maximum of four.

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 CTK0*AA thermostat. Any other system configurations are considered invalid ComfortNet systems and must be connected as a traditional (or legacy) system. The table below compares the valid CT systems.

Modular Blower

Modular Blower

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 outdoor units typically do not return information to the thermostat.

On the other hand, the indoor unit, outdoor unit, and thermostat comprising a ComfortNet system “communicate” digitally 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 request and receive information from both the indoor and outdoor 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 system.

Two-way digital communications is accomplished using only two wires. The thermostat and subsystem controls are powered with 24 VAC Thus, a maximum of 4 wires between the equipment and thermostat is all that is required to operate the system.
