The MBVC***1 Blower Cabinet is a modular air handling unit designed for use in split air-conditioning systems, functioning as the indoor component when combined with a cased evaporator coil. It can also operate as an electric furnace when an electric heater is installed. This device is part of the ComfortBridge™ Technology family, offering advanced digital communication capabilities and simplified wiring.

Function Description:

The blower cabinet serves as the indoor section of a split air-conditioning or heat pump system. It can be matched with a remote condensing or heat pump unit. When equipped with an electric heater, it functions as an electric furnace. The unit's internal algorithms automatically control cooling and heating stages based on simple 24VAC thermostat inputs (Y for cooling, W for heating, G for fan operations). This allows for 2-stage or inverter Air Conditioner/Heat Pump functionality. The control board does not accommodate an O wire thermostat input for reversing valve signals.

Usage Features:

Installation Flexibility: The unit can be positioned for upflow, counterflow, horizontal right, or horizontal left operation. Zero clearance is allowed on all sides for combustible materials, but 36 inches should be allotted on the door side for maintenance.
Electrostatic Discharge (ESD) Precautions: To protect the integrated control module, users must discharge their body's static electricity before touching the unit or any connected wires. This involves firmly touching a clean, unpainted metal surface of the modular blower near the control.
208/230 Volt Line Connections: The unit is factory-connected for 230V operation. For 208V operation, the red wire from terminal 3 of the transformer must be disconnected and connected to terminal 2. Power supply wires (red and black) must be connected using provided wire nuts and electrical tape. A ground wire must be connected to the ground lug inside the unit.
Low Voltage Wiring: A 24V-control voltage connects the air handler to the room thermostat and condenser. Minimum 18 AWG copper wire is required for installations up to 150 feet. Low voltage wiring should not interfere with blower operation or routine maintenance.
CoolCloud™ HVAC Phone Application: The unit is Bluetooth-ready and integrates with the CoolCloud™ HVAC phone application. This app allows contractors to commission the unit, perform software updates, and troubleshoot. Users can view model information, active diagnostic error codes, and test operational modes (heat/cool/fan) directly from their phone. The application automatically notifies users when software updates are available.
Communicating Outdoor Units (Quick Start Guide): For communicating outdoor units, only Y (cooling) and W (heating) inputs from the thermostat are required. Internal algorithms manage staging. A single-stage 24VAC thermostat should be set up to control a single-stage AC outdoor unit and single-stage electric heat. The 1 & 2 wires connect the indoor and outdoor units for communication.
Non-Communicating Outdoor Units (Quick Start Guide): For non-communicating outdoor units, airflow must be set in the "ton" menu on the PCB or via the CoolCloud HVAC app to prevent "IdL" error codes and ensure blower operation during cooling calls. For two-stage electric heat, only a single W input is needed, with internal algorithms controlling staging.
Charging Instructions (Inverter Outdoor Unit): To charge an inverter outdoor unit, apply a G call (FAN CALL) to the MBVC control, ensuring the blower is running. Then, follow specific push-button procedures on the outdoor inverter control board to enter and exit charge mode.
Charging Instructions (Two-Stage Outdoor Unit): For two-stage outdoor units using the CoolCloud HVAC app, energize the outdoor unit to 49% capacity or lower using the cooling icon in the outdoor unit menus, then charge according to the outdoor equipment's information. For single-stage outdoor units, provide a cooling call from the thermostat and charge accordingly.
Electric Heat Kit Testing: In the CoolCloud HVAC app, select the electric heat icon and choose any value less than 50% for low stage operation and greater than 50% for high stage operation to confirm proper function.
Dehumidification: The unit supports dehumidification by reducing blower speed during combined cooling and dehumidification calls. The control board has a 24V dehumidification input (DH). Users can configure the Dehum Logic Menu (DHL) to "Hi" or "Lo" via push buttons or the CoolCloud HVAC app, depending on whether the humidistat closes or opens on humidity rise.
Auxiliary Alarm Switch: The control includes a 24VAC Aux Alarm (CON-DENSATE IN/OUT) for a condensate switch. By default, the switch is normally closed and opens when the evaporator coil base pan water level is undesirable, triggering an "EOF" error code and turning off the outdoor condensing unit.
7-Segment Display and Push Buttons: Three on-board push buttons (Left, Center, Right) allow navigation through indoor and outdoor system menus. Left and Right buttons scroll through menus and options, while the Center button enters menus and selects options.
Accessory Control (Humidifiers, Dehumidifiers, Ventilators): For external accessories, ensure the 24VAC thermostat can control them. Connect accessory control wires from the thermostat to the devices. If the thermostat provides a continuous fan call (G signal), ensure the thermostat G terminal is connected to the indoor unit's G terminal. Select appropriate fan-only airflow via push buttons or the CoolCloud HVAC app.
Ramping Profiles: The variable-speed circulator offers four ramping profiles (A, B, C, D) to enhance cooling performance and comfort. These profiles can be selected via the CoolCloud app or push buttons.
Electric Air Cleaner: The control has an Accessory Relay and ½-inch accessory terminals (EAC-IN and EAC-OUT) that are normally open. The relay closes when the blower is running, providing continuity between the terminals. It's recommended to use 24VAC with these terminals, limiting current to 1A.

Maintenance Features:

Bi-Annual Maintenance: A bi-annual maintenance checkup by a qualified servicer is strongly recommended before heating and cooling seasons.
Filter Replacement/Cleaning: Filters must be checked at least monthly and replaced or cleaned as required. Operating the unit without a filter can lead to dust and lint buildup, reduced efficiency, equipment damage, and fire. High-efficiency filters are available.
Motor Lubrication: Indoor and outdoor fan motors are permanently lubricated and do not require additional oiling.
Aluminum Indoor Coil Cleaning: This unit is equipped with an aluminum tube evaporator coil. The safest cleaning method is flushing the coil with water. Coil cleaners containing corrosive chemicals (e.g., chlorine, hydroxides) should not be used, as they can cause premature aluminum evaporator coil failure. An alternate cleaning method involves using products listed in TP-109, followed by thorough rinsing.
Troubleshooting (Before Calling Servicer):
- Confirm thermostat settings.
- Wait 15 minutes for devices to reset automatically.
- Check the electrical panel for tripped circuit breakers or failed fuses.
- Check the disconnect switch near the indoor furnace or blower.
- Check for obstructions on the outdoor unit and indoor air inlets/outlets.
- Check and clean/replace the filter.
- Listen for unusual noises; if present, call a qualified servicer.
Troubleshooting Matrix: The manual provides a detailed troubleshooting matrix linking symptoms of abnormal operation to diagnostic/status LED codes, fault descriptions, possible causes, and corrective actions. This helps identify and resolve issues such as communication errors, open fuses, auxiliary switch errors, invalid memory card data, circulator blower motor failures, and airflow problems.
