Product Data VA3B VB5B VC5B Heat Recovery Ventilators VA3B VC5B The Heat Recovery Ventilation (HRV) system offered by Carrier is the finest unit on the market today. The VA3B, VB5B, and VC5B provide efficient and cost-effective heat recovery during the heating season when needed most. As temperatures drop below 23 F ( 5 C), indoor air is recirculated periodically through the heat exchanger core to prevent frost from forming. Competitors methods of supplementary electric defrost waste energy. Unlike rotary wheel heat exchangers which mix air streams, these cross-flow or counter-flow heat exchangers ensure that there is no mixing of the stale air stream with the fresh outdoor air stream. A filter installed on the incoming outdoor air stream removes large airborne particles from the intake air stream before they enter the heat exchanger and reduces the maintenance required. The units acoustically engineered design makes them the quietest on the market and ensures that comfort is felt, not heard. Unlatching 2 suitcase style latches allows easy removal of the filters and core for cleaning. VB5B Copyright 1995 Carrier Corporation This document was created with FrameMaker 4.0.4 Form VA3B-1PD

Accessory description and usage Push Button Timer Enables the unit to override mode selected and operate at high speed for 20 minutes. Ideal for special activity areas such as bathrooms or kitchens where high-speed exhaust is needed for short periods of time. Kit includes 12 wall-mounted timers and a control unit (12v). 60-Minute Timer Allows the user to override current operation mode and operate at high speed. Adjustable from 10 to 60 minutes with an additional 20 minutes added from the control board. Ideal for areas requiring high-speed exhaust for longer periods of time (12v). Balancing Kit Installers tool complete with: 1 Magnahelix gage (0 2.5 in. H[in 2 ]O), 2 6-in. diameter flowmeters, 4 pieces of plastic hose and instructions. Packaged in a metal tool box, this kit contains all the instruments needed to balance an HRV installation. Control features Basic Control: Allows the user to manually set fan speed to low or high as required to maximize comfort. Standard Control: Offers automatic dehumidistat control and the option to select continuous or intermittent fan operation. Setting the wall control to low will activate the continuous mode. Automatic Control: In addition to the features found with standard control, this package offers a recirculation mode and an air ionizer. These controls may only be used to operate stand-alone units with the defrost option which enables the recirculation feature. CONTROL DESCRIPTION FAN SPEED CONTROL * Air exchange with outside. No air exchange with outside. DEHUMIDISTAT CONTROL CONTINUOUS MODE* INTERMITTENT MODE* CIRCULATION MODE Basic Yes No Yes No No No Standard Yes Yes Yes Yes No No Automatic Yes Yes Yes Yes Yes Yes AIR IONIZER Control description and usage Fan Speed Control Enables user to modulate fan speed from low to high air exchange with outside. Dehumidistat Control Allows the user to select the relative humidity level at which the unit would change fan speed for dehumidification in the winter months. Continuous Mode If the relative humidity inside the building is lower than selected, air exchange occurs with the outside at low speed. If the relative humidity inside the house is higher than selected, air exchange occurs with the outside at high speed. Ensures continuous air exchange for constant air quality. Intermittent Mode If the relative humidity inside the building is lower than selected, no air exchange occurs and the system turns off. If the relative humidity inside the house is higher than selected, air exchange occurs with the outside at high speed. Ensures minimum air exchange level when the building is unoccupied to minimize operating costs. Circulation Mode If the relative humidity inside the building is lower than selected, the ambient air would be circulated and filtered at high speed. If the relative humidity inside the house is higher than selected, air exchange would occur with the outside at high speed. Ensures continuous movement and filtration of air for maximum comfort. Available with automatic control only. Air Ionizer Neutralizes airborne particulates by negatively charging them. For use on independently installed systems. 8
Automatic defrost cycle features All models offer a non-electric defrost cycle feature which prevents frost and ice buildup within the heat recovery core. When the outside air temperature falls below 23 F/ 5 C it is electronically sensed and the dampers close the outside air ports. This allows warm indoor air to recirculate within the heat recovery core. The frequency of this cycle increases as the outside air temperature decreases.
