The present invention provides a method for enhancing dehumidification of a conditioned space, while optimizing the effectiveness of Indoor Air Quality (IAQ) devices that are present in the HVAC system. After the system compressor is shut off, the actual space humidity is compared to the desired humidity. If the actual humidity is very close to or lower than the desired level the indoor blower (air handler) is allowed to continue running. However, if the actual humidity is greater than the desired level by a specified amount, the blower is forced off for a period of time proportional to the difference between the actual and desired humidity. At the next compressor activation, the blower is allowed to run as normal.

Dehumidification enhancement via blower control

The present invention is an improvement to previously known systems for controller area networks and the method of communicating across such networks. The system and method introduces interpolated time markers to provide higher resolution bit container, for communicating data bits across the data bus of a three-wire controller area network. The interpolated time markers allow devices on a controller area network to effectively double tie amount of bandwidth available for communication and can in some cases even further increase the bandwidth beyond a factor of two.
