On - The system has a variable speed blower.

Factory default is OF (Off)

Option 42 — Variable Speed Super Dehumidification

This option will only be available if the Variable Speed Blower setup (Option 41) has been set to ON.

OF - The fan output (G) is energized when the compressor is on for cool to dehumidify functionality.

On - The fan output (G) is de-energized when the compressor is running for cool to dehumidify functionality. In this setup the fan will run at very low speed because a Y/Y2 or Y1/W2 is present but the G signal is not. The fan output (G) will be energized any time the compressor is energized in response to a cooling demand.

Factory default is OF (Off)

Option 43 — Intelligent Heat Staging

This function is only available if the equipment configuration is a single speed heat pump (Option 01 = HP) and the thermostat is a Tx-PRH or Tx-NRH model. The Y1/W2 output, which energizes the second stages of heat, is only populated on these models.

Off - Electric heat will not be staged.

On -Three stages of electric heat will be staged.

This switch should be set to On if the HVAC equipment has two banks of strip heaters. When electric heat is required, the thermostat will energize the smallest bank first (W1 only), then the larger bank (turning the smaller bank off - Y1/W2 only), and then both banks together (both W1 and Y1/W2). When power is cycled to the thermostat, this unit configuration will be displayed as HS.

Factory defaults is OF (Off)

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.
