See Fig. 16 for outdoor temperature/indoor humidity relationship in auto humidify mode.

3.Humidify Off

The humidify function can be turned off completely. This does not re- quire changing existing setpoints.

To Select Humidification (programmable)

Press the soft key below the humidify icon to bring up humidity select screen. Humidify options are only available when in Heating mode. When system is in AUTO mode, humidify options are available if the last system operation was a call for heat.

To Select Humidification (non-programmable)

Press the features button twice. The first press displays the outdoor air temperature and the second press displays the humidity value and humidify target.

Pressing the mode button shall cycle through the available humidification selections (Off, Humidify and Auto Humidify).

Additional Humidify Comments

The humidifier is actually turned on when humidity is 1% below setpoint and turned off when it reaches 1% above setpoint. This built-in hysteresis prevents humidify output from toggling on and off when humidity level is near setpoint.

Dehumidification

Dehumidification is done only during cooling. Depending on type of equipment used, compressor speed, blower speed, setpoint adjustment, and equipment cycling are modified to provide added dehumidification. A dehumidification setpoint (separate from humidification setpoint) is available to the homeowner. It can range from 46% to 66% relative humidity. When actual humidity is higher

A07048, A07049 specifications

The Bryant A07049 and A07048 are notable entries in the line of ductless mini-split systems designed for efficient heating and cooling. These models are well-regarded for their robust performance and innovative features that cater to both residential and light commercial applications.

One of the main features of the Bryant A07049 and A07048 is their advanced inverter technology. This technology allows the units to modulate their compressor speed, resulting in a more consistent indoor temperature. By adjusting cooling or heating output based on real-time demand, the units enhance energy efficiency while providing quiet operation and improved comfort.

The cooling capacity of the Bryant A07049 is rated at 7,000 BTUs, making it suitable for medium-sized rooms, whereas the A07048 has a slightly lower capacity, ideal for smaller spaces. Both models excel in providing rapid temperature control, allowing users to enjoy their desired environment swiftly. The quiet operation is a significant advantage, with sound levels as low as 24 decibels, making them perfect for bedrooms, offices, or other noise-sensitive environments.

Installation flexibility is another remarkable characteristic of the Bryant A07049 and A07048. Their ductless design eliminates the need for extensive ductwork, simplifying installation processes. Both models come with easy-mount wall brackets, and the refrigerant lines can be run through a small, discreet opening in the wall, maintaining the aesthetic appeal of the living space.

Energy efficiency is a standout feature of these models, boasting high Seasonal Energy Efficiency Ratio (SEER) ratings. This high-efficiency operation not only reduces energy bills but also minimizes environmental impact. Additionally, both models include a built-in programmable thermostat that allows users to schedule their heating and cooling preferences, enhancing convenience and further optimizing energy use.

The Bryant A07049 and A07048 also feature a multi-stage filtration system. This advanced filtration captures dust, allergens, and other particulate matter, promoting cleaner air circulation which is particularly beneficial for those with allergies or respiratory conditions.

In summary, the Bryant A07049 and A07048 mini-split systems deliver versatility, energy efficiency, and user-friendly operation. Their modern design, quiet performance, and advanced technologies make them excellent choices for individuals or businesses looking to enhance comfort while being mindful of energy consumption. Whether used for supplementary heating or cooling, these units are engineered to meet a variety of climate control needs effectively.
