RAISING THE STANDARD: THE NEW WEATHERMAKER® 80% FURNACES

Through Carrier’s Partners In Development (PID) program, many Carrier dealers fromacross the country have been an integral part of the design process for the new furnaceline – right from the start.

So it’s no surprise that the primary new features of the redesigned line – which includessingle-speed, two-stage and variable-speed models – have a direct impact on a dealer’sbottom line. The biggest dealer benefits: increased installation flexibility, reducedstocking requirements and enhanced serviceability – all of which can contribute tohigher dealer profit margins.

DESIGNED FOR DEALERS

WeatherMaker8000VS (58CVA,as in ComfortHeatVariable Speed, or58CVX for low NOx)

While the specific models offer different performance features, all of them share the basicdesign benefits that make a dealer’s life easier.

Installation flexibility.

The most striking change in the new furnaces is a shorter (33 1/3") height and a truemultipoise design that requires little modification (remove three screws and rotate the ventelbow), even for downflow or horizontal applications.

The innovative design enables the new furnace models to be used in upflow, downflow,horizontal left and horizontal right applications, and makes a downflow variable-speedapplication available for the first time. It also allows for 13 possible venting configurations (see graphic at bottom). Plus, with the badge’s new design, you can simply pop off the logo,and snap it back on so it’s always facing right-side-up, no matter what the furnace orientation.

The combination of the shorter size and the multipoise capability gives dealers significantinstallation flexibility and system design advantages, such as freeing up space in smaller homesfor additional closet space or to allow room for air cleaners, humidifiers, better plenums, etc.

MAKING LIFE EASIER … AND PROFITS HIGHER

The new raised-door designmakes controls and components easier to access, for faster, moreconvenient service.

Reduced inventory requirements.

The multipoise capability has positive implications for inventory management as well.Dealers can accommodate 60 percent more applications than they could with the prior design,and can do it with 40 percent fewer SKUs. So the design change simultaneously reducesstocking requirements and increases application possibilities, which can significantly boostdealer profit margins.

Easier service access.

The new models also will feature a raised-door design that gives service technicians open accessto the controls and components, rather than having to reach in between the sides of thecabinet and work in a confined space. With easier access, less time is needed to service the units.

What’s New: WeatherMaker® 8000 Line Enhancements

Chimney-friendly. An additional benefit of the multipoise design is that the single stage models now are chimney-friendly compatible, so there’s no need to stock a specific furnace for chimney-friendly-only applications, such as the 58YAV.

While the most visible changes to the WeatherMaker® 8000 line may be on the outside, yourcustomers could notice the biggest benefits from improvements on the inside – especially to the control board.

Three fan speed settings.

With the three upper-tier furnaces, dealers can now offer customers three continuous fanspeeds (the heating speed, the cooling speed, and now a third discretionary speed, usuallyslower for continuous fan use). The homeowner has the ability to choose the fan speed forcontinuous fan operation at the thermostat, by simply turning the fan switch off, and thenback on one to three seconds later. The availability of slower fan speeds enables homeowners to enjoy the benefits of continuous fan operation – such as cleaner, fresher air and more even temperatures throughout their home – while keeping sound levels and energy usage to a minimum.

Enhanced dehumidification.

When combined with a ThermidistatTM Control and operating in cooling mode, the three top-tier models can automatically reduce fan speed to help reduce excess humidity in the air.Lowering the humidity level allows homeowners to enjoy greater comfort without having tolower the thermostat set point.

In addition, the fan will shut off at the end of the cool to dehumidify cycle, eliminating the re-evaporation of condensate from the evaporator coil.

Two-Speed Puron compatible.

The three top-tier furnaces also offer full two-speed A/C compatibility. When there is a call for low-stage cooling, the furnace control board reduces the fan speed, for improveddehumidification.

Intelligent cool staging.

Before, a two-speed thermostat or ThermidistatTM Control would have been required to controlthe staging of the outdoor unit. Now dealers have a choice, because the furnace control candirect the two-speed air conditioner or heat pump to operate in high speed or low speed, usingthe same type of patented adaptive algorithm that has been the hallmark of Carrier’s MVP heatstaging for years. (But dealers should choose carefully: the Thermidistat Control provides itsown remarkable set of benefits!)

Improved diagnostics and non-volatile memory.

The new control board features an extensive list of LED fault codes to help technicianstroubleshoot problems. And, with a three-hour lockout and an auto-reset feature, fault codes won’t be lost due to a power outage, and no manual reset is required.

Dealers can now control a two-speedair conditioner directly from thefurnace (top three models) or throughthe Thermidistat Control, which offersa variety of additional benefits.

While the new WeatherMaker® 8000 line offers homeowners several impressive benefits as well,the most significant of them is one they shouldn’t even notice: dramatically reduced soundlevels. Here are some highlights:

Quiet operation.

With lower burner noise, added sound baffling and relocated components, the new 80% linewill offer noticeably lower sound levels – even the single-speed models. In fact, sound level testsindicate that the new models are the quietest of all the 80% furnaces Carrier tested.

Easier filter maintenance.

On the three upper-tier models, an external media cabinet is supplied with the furnace, so filteraccess can’t get much easier than that. But even on the base model, replacing a filter is simplerbecause the homeowner does not need to open up the unit to reach the filter.

FOR HOMEOWNERS: QUIET, AFFORDABLE COMFORT

“ [The homeowner] doesn’t

have to turn the TV up now

when the furnace comes

on. She’s tickled pink.”

Rich Dykstra PID Dealer

The top three models include aconvenient external media cabinet,making filter access a breeze fordealers or homeowners.

A low-speed setting for contin-uous fan now lets single-speedcustomers enjoy greater comfort.

Improved comfort and dehumidification.

While homeowners with variable-speed models have always enjoyed the ultimate combinationof energy savings and comfort, the intelligent cool staging feature and three fan speed presets on the control board now allow single-speed customers to enjoy a taste of them as well. A low-speed setting for continuous fan can enable homeowners to have better air quality and moreconsistent temperatures without exorbitant energy costs.

While the redesigned WeatherMaker® 8000 line may seem new, the idea for it has actually beenaround for a while. The line has been developed over a four-year period, in conjunction withCarrier Partners In Development dealers to address their needs and help them improve theirprofitability.

To make sure the new design exceeds expectations, Carrier has had roughly 100 “LimitedProduction Run” (LPR) units in field testing with PID and other dealers and consumers acrossthe country since November 2000 (see map). An additional 32 units have been undergoinggrueling reliability testing at the factory since April 2000 – with twice the normal testingrequirements on the heat exchanger life (200,000 cycles).

The LPR field installation criteria were also mixed according to a specific matrix (see table), tomake sure the line was tested across a variety of installation variables. Specific criteria includedpoise (upflow, etc.), fuel (natural gas or LP), location (attic, closet, garage, etc.) and vent type(chimney or category 1).

The input received from the initial PID planning sessions and the LPR field testing has resultedin several mid-stream design improvements. Overall, the comments from dealers (see next page)and homeowners alike have been very positive and have confirmed that the new line isexactly what dealers asked for, enhancing their profitability and offering a wide range of benefits for dealers and consumers alike.

PID DEALER PERSPECTIVES

“I thought it was going to be a corporate rubber stamp process, but they really listened to us … I had the opportunity to talk to [a homeowner] after we installed it, and she couldn’t believe the difference in her home. It’s cleaner, it’s quieter, and she doesn’t have to turn the TV up now when the furnace comes on. She’s just tickled pink with it.”

Rich DykstraD. M. Dykstra and CompanyChicago, IL

“The multipoise capability will be a big benefit to dealers, specifically in horizontal or downflow applications ... It really cuts down on the installation time … It’s a nice compact unit, it will fit into the spaces we need, and it’s that many less products we need to keep in our inventory.”

Tim CroppCropp-MetcalfeFairfax, VA

“The serviceability of the unit was definitely a big concern to the PID team early on as we were shortening the height of the furnace. That led to the door design and bringing all the controls forward.”

Phil FavretFavret CompanyColumbus, OH

“I’ve had zero problems with the unit … It gets an A+ from all the people in our organization.”

Reve PorterReve Porter Inc.Indianapolis, IN

“I think they did a very good job of listening and turning what we asked for into a reality.”

Q: Will there be a chimney-friendly product to replace the 58YAV?

A: All WeatherMaker 8000 furnaces are targeted for chimney-friendly applications, includingtwo-stage and variable speed models. (Some of the LPR applications are two-stagechimney vent applications, in fact.) We are continuing with qualification testing andshould have final confirmation by May 1, 2002.

Q: Will twinning be allowed?

A: All WeatherMaker 8000 furnaces are targeted for twinning applications, including two-stage and variable speed. We expect to have a final answer when qualification testing iscompleted, no later than May 1, 2002.

Q: In horizontal applications, will the WeatherMaker 8000 furnace be approved for “bottom return” (as opposed to “end return” only)?

A: All WeatherMaker 8000 furnaces are targeted for bottom return in horizontal applications,including two-stage and variable speed. This issue is currently being evaluated inqualification testing and should be resolved by May 1, 2002.

Q: Will this furnace fit better with furnace coils?

A: Yes. The flanging on both the furnace coils and the WeatherMaker 8000 furnace has beenrevised to eliminate interference. The furnace coil changes will improve fit up with the condensing furnace line as well.

Q: What other products are changing in conjunction with this new platform?

A: From an appearance standpoint, the new door color (which is the current outdoor unit color, American Sterling) will create a better matching system. The new casing finish — which includes hints of American Sterling — will also be used on furnace coils and mediacabinet doors. Also, the humidifier color will convert to American Sterling .
