Today’s homes require special consideration in order to maintain uniform comfort throughout.  Ideally, there should be no more than a 2°F temperature difference between any two rooms at any given time according to the Air Conditioning Contractors of America (ACCA).

One of the most popular residential applications for zoning is a bonus room or FROG (finished room over garage).  Without a separate zone thermostat, comfort is impossible in a bonus room.  The constant year round complaint about Bonus Rooms without a thermostat is, “It’s Too Hot”.

Zoning with multiple thermostats controlling a single heating/cooling unit is the solution for maintaining indoor temperature to fit individual needs.  Zoning provides ultimate comfort by providing heating and cooling where and when you desire by locating multiple zone thermostats in critical areas.

Net/X™ Network Controllers

The Net/X family of Network Controllers is the heart of the NetworkThermostat HVAC control networks.  There are several different network controllers to satisfy the requirements of any installation.  The entire Net/X Network Controller family enables simple integration with any control system or personal computer.  The controllers accept simple ASCII commands using a published open protocol and replies with readable text answers.  The entire family of controllers has built-in intelligence to correct conflicting and illegal thermostat settings to prevent damage to equipment from programming errors.

All Net/X network controllers are commercial grade controllers, providing high reliability in any application.  The controllers include a real-time clock/calendar which allows simple, yet robust environment control.  The real-time clock/calendar is a significant importance to most of our customers.  It allows the Net/X system to run in a 'stand-alone' mode, where no other controller, PC or automation system is required for scheduling set points and modes of operation.   When used in combination with the Net/X Command Center software, simply point and click to create your schedules, then click to download them into the Net/X network controller, and you're done!  The thermostat schedules will run automatically at the time(s) designated.  There are also two versions of the controllers, the NT-SSA32/CLK Network Controller (for 16 or less thermostats) and the NT-SSA16/CLK Network Controller (for up to 32 thermostats)!   In addition, using the Net/X Command Center software allows you to monitor and control as many Net/X Network Controllers as needed for your site, no matter how large.

Net/X™ Wireless Solutions

Connect your Net/X™ thermostats wirelessly to the network from hundreds and hundreds of feet away.  These new modules are extremely valuable options that deliver flexibility, and reduce installation and set-up time.

Large or small, new construction, expansion or retrofit, our mesh-network wireless options make installation a snap.  Our innovative solution takes energy savings and efficiency to a new level.  Based on the IEEE standard 802.15.4 for wireless networks, our groundbreaking technology allows each Net/X™ wireless module to function as a device communications gateway and simultaneously as a repeater for the entire network, ensuring reliable transmission with ranges never before seen with wireless systems. 

You can place the Wireless Coordinator Module (WCM-1) anywhere in the facility within 1,000 feet of the Network Controller.  This module interfaces the wireless thermostats to the entire network.  Each WCM-1 can coordinate up to 32 Net/X wireless thermostat modules, and you can have as many WCM-1 coordinators on the site as you have Network Controllers.  The sophistication of the electronics allows hundreds of thermostats to be controlled on the same site without interfering with each other or with other wireless systems.

Wireless Backplate Modules

Each Wireless Backplate Module (WBM-1) connects a Net/X™ thermostat to the WCM-1.  Simply install the backplate on the wall, connect the thermostat wires, push the link button to sync communications with the coordinator, and the installation is done!  Up to 32 wireless thermostats can be used with each Network Controller.

Net/X™ Remote Temperature Sensors

Net/X provides an entire family of remote sensing products.  The NT-IDS, NT-DUCT, NT-ODT and NT-SUPPLY communicating temperature sensors are designed to work in conjunction with the Net/X™ thermostat family.  The remote sensor network allows multiple sensors to be connected in a daisy-chain manner to a Net/X thermostat.  The intelligence of the network includes automatic averaging if multiple sensors are connected.  The connected Net/X thermostat also automatically removes the temperature sensor internal to the thermostat from the temperature calculation.  This feature allows the thermostat(s) to be placed in a locked enclosure or a remote location (such as a closet) without the need to remove the Net/X thermostat's sensor.

The NT-IDS is the indoor temperature model that allows remote sensing of temperature in the occupied space, and the NT-DUCT and NT-SUPPLY include an 8" stainless steel probe & box for use at a return air duct and supply air plenum, respectively.  The NT-ODT is the outdoor temperature model that allows monitoring of the ambient outside temperature.  The NT-SUPPLY can be used in place of the outdoor sensor, allowing monitoring of the HVAC system's supply air temperature.  Integration with the Net/X™ thermostats is a simple three wire bus supplying power and data to the thermostat.  An external 10K sensor probe may be connected for complete versatility of environments.  Screw terminal connections are included for power, data, and external sensors.

The resulting drier air allows for higher set point temperatures while improving the overall perception of comfort. Think of it in terms of taking a hot shower. Even though you may have the exhaust fan running, the air inside can still get steamy. The fan is just not enough. Now open the bathroom door. The cool sensation you feel when the steamy air is removed is similar to the added comfort you can experience as the Comfort Control Center removes the excess moisture…FROM YOUR ENTIRE HOME!

The fully programmable Comfort Control Center works by intelligently controlling your system’s blower motor speed based on the unique environmental conditions in your home. By allowing the warm, humid air to stay in contact longer with your system’s evaporator coil, the Comfort Control Center improves your system’s effectiveness at removing moisture from the air…with greater system efficiencies. Additionally, when used in conjunction with a system equipped with advanced IAQ devices, the CC750 also allows these devices to operate more effectively, making it ideal for asthma or allergy sufferers. During colder months, the CC750 will even provide warmer air discharge temperatures for homes equipped with a heat pump.

Why spend thousands of dollars on upgrades or a new variable speed system when the CC750 Comfort Control Center can deliver year-round, in-home comfort – effectively, efficiently and for a fraction of the price?

Energy Recovery Ventilators (ERVs)

Studies show that the Indoor Air Quality (IAQ) of the average home can be up to 100 times more polluted than outdoor air.*

Invisible pollutants produced by common household substances, plus dust and excess humidity that gets trapped in today’s houses, can increase your risk of chronic respiratory illness and your home’s risk of serious structural damage.

Central ventilation and filtration effectively eliminate airborne pollutants and excess humidity.

Venmar  manufacturers three types of Energy Recovery Ventilators (ERVs) to provide your home with fresh clean air in every room of your house throughout the year:

• DUO 1.2, 1.4 or 1.9 - Highest industry rated Total Recovery Efficiency (TRE) **
• CONSTRUCTO 1.0, 1.5 or 2.0 – Compact cross-core ERV
• HEPA 4100 - ERV with HEPA*** filtration removes 99.97% of 0.3 micron particles.

Venmar ERV units expel polluted and humid air from your home to the outside and replace it fresh air several times a day.

There are many applications where heating and cooling is required for areas separated from the main area.  This could include room additions such as sun rooms or bonus rooms above a garage that were finished after the home was constructed.  If the main central heating and cooling system capacity is adequate, a zone control system probable offers the best solution.  However, if the main heating and cooling system is not large enough to handle the additional conditioned space, a mini-split heat pump is an ideal low cost solution.

Mini-splits offer separate thermostat control for these areas which is absolutely necessary if comfort is to be achieved.  Merely adding additional ducts from the existing central heating and cooling system to remote areas or room additions simply will not provide comfort unless a thermostat is included.

All AmericAire mini-split units use modern R410A refrigerant rather than R22 refrigerant which is being phased of production.

Respiratory ailments, often attributed to poor air quality, represent the third largest cause of death in the U.S., ranking only behind heart disease and cancer, according to the American Medical Association.  Removing harmful particles and chemicals plus removing pollutants, pollen, mold and mildew from the air you breathe is the key to cleaner, healthier air.

Polarized-Media Electronic Air Cleaners

Dynamic Air Cleaners offer unparalleled 97% capture efficiency of 0.3 micron particle  sizes using a unique patented combination or air scrubbing, electrostatic polarization and activated carbon and thus, providing clean, healthy air in your home or office.  1” panels fit directly into existing filter grilles or filter racks and are powered using simple 24 volt wiring connected to the central HVAC system.  No cells or filters to wash.  Just periodically replace the polarized charcoal media.

Advanced Germicidal PCO System

The Dynamic Advanced PCO System destroys pollutants using ultraviolet light in a three step process.  First, the pollutant adsorbs the surface of the catalyst.  The pollutant and catalyst are then exposed to the photons of the UV light.  The light energy activates the catalyst which breaks down the pollutant into non toxic products.  Odors and vapors are vaporized by the UV light in much the same way that a drop of cold water is vaporized when it drops into a hot skillet.  Germicidal UV lamps without the PCO advantage are also available.

Many homes suffer from excessive humidity and/or poor ventilation, which may lead to an increase in allergens such as mold.  Studies have shown that dust mites and mold are two of the most common allergens present in higher humidity climates.  Excessive humidity in the crawlspace can lead to serious deterioration of wood and even buckling floors.

Santa–Fe dehumidifiers are free standing and designed specifically for crawl spaces. Controlling humidity is crawlspaces is a critical component of overall humidity control. 

Ultra–Aire Whole House Ducted Dehumidifiers

Fantech offers a wide variety of bath, kitchen and dryer ventilation solutions.

Gone are the days of a single bath fan in the center of the room.  The key to proper ventilation is the oversized bath filled with luxurious amenities is true spot ventilation at one source.  Choose between a quite, efficient centrifugal fan with multiple exhaust grilles in a single bath or multiple baths.  Integral halogen or florescent lights are available as an option.

Fantech kitchen ventilation keeps kitchens clear of smoke, grease, steam and odors with a ventilation system that works quietly and efficiently by utilizing a powerful exhaust fan located away from the living area with a silencer to minimize noise and a hood liner that fits beautifully in your custom hood design.

According to some dryer installations instructions and local building codes, dryer booster fans are required when the length of the duct exceeds 25 feet with no bends of 15 feet with two bends.  A Fantech “Intelligent” dryer booster fan can be used effectively to boost dryer exhaust in duct runs up to 130 feet using a patented pressure sensing switch to automatically turn the booster fan on.

Ventilation control is essential to energy efficient homes.  Energy efficient homes can be achieved by building tighter homes and reducing unnecessary leaks.  Some benefits to energy efficient homes includes; lower monthly utility bills, increased thermal comfort, higher resale value for the home and environmental benefits as well.

However, a tight construction home compromises the air quality within.  Not only does a tight home retain the energy in the home, it also retains the pollutants that are caused by everyday living. 

The Air Cycler is a low-cost device that ensures the right amount of fresh air within a home to maintain energy efficiency and excellent air quality.   Easily adjustable, the Air Cycler allows the homeowner to choose the exact number of minutes per hour of fresh air desired.
