GENERAL INFORMATION

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 when used with an electric heater.

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.

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.

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.

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.

COMFORTNET™ SYSTEM

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.

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.
