No other unit in the industry offers so many energy management features as standard. With the ability of the digismart ptac to reduce operating costs by 35%, there is no need to settle for anything less than an amana brand ptac. Ptac systems are single units that provide both heating and cooling operations from one product. This is different from the air conditioning systems used in most north american homes which use split systems. This name is derived from the fact that two components are required to complete the system; an indoor coil (inside the home) and an external condenser (outside the home). Using electricity as its power source, the ptac compressor pumps refrigerant through the system. The refrigerant attracts heat and moisture from indoors and then transfers it outdoors.

The refrigerant is used to create a heated indoor coil. As air passes over the heated coil the heat is transferred to the air inside the room creating warm air. Ptacs can rapidly remove heat and moisture from indoor air. You simply set the units thermostat to the temperature that you desire and the unit automatically cools to that level. You can manually select fan speed or use the automatic fan speed setting.

When you need the room to be heated you use the same basic settings. Just set the thermostat to the temperature you want and select the heating function. Ptacs are easy to install because they come in standard sizes and shapes. Regardless of the heating and cooling load requirements, the unit is the same size.

Since both the heating and cooling systems exist inside a single unit, installation is easier than the installation of a split system. Unlike split-system heating and cooling systems which condition whole buildings through the use of ductwork, ptacs cool and heat only the rooms or spaces where they are installed. This means you cool or heat only what you want with individual temperature control. With multiple ptacs installed, you can easily control indoor temperature on a room to room basis. Amana brand ptacs have an eer of up to 12.8 (on heat pumps, a cop of up to 3.6) to keep energy consumption to a minimum.
Amana brand units are equipped with ems technology to better control room temperature and save energy dollars. Ready for wireless or wired operation. Owner-controlled settings allows automatic temperature setback when unit is idle. Amana brand digismart units connected to a tridium jace controller automatically build their own wireless network. Remote occupancy sensor, remote thermostat, rf antennas, and rf platform controller provide everything you need to reduce energy costs by 35%.

Ptac – contains all the processing power and software to manage energy consumption, unit status and comfort performance. Occupancy control – the remote sensor above the door determines if the room is occupied or not. If occupied, normal routines run, but if unoccupied the ptac can change temperature settings based upon owner settings.
Remote thermostat – the digismart remote thermostat works just like the one at home but unlike other ptacs does not disable the unit controls. Remote and ptac control panels work at the same time and show the same information.

Set-up – best of all, no wiring. All of the peripheral devices can be installed by your handy man without calling an expensive electrician. A touch of a button connects the peripherals to the air conditioner in that room.

So once the network is up and running, amana ptacs can be integrated with your existing building management system or if desired, controlled remotely through the internet. On-board energy management system (ems).

Set-back mode – the owner can determine amount of time unit left ‘untouched’ (buttons not pushed) before the ptac begins a set-back routine and new thermostat temperature takes effect, also selected by owner. Maintenance status – separate green led indicator light to show if unit requires maintenance. Electronic temperature limits – owner can set separate cooling and heating temperature ranges and limit operation to one-degree increments, saving energy by preventing guests from over-cooling or over-heating. Enhanced dehumidification cooling mode – the unit can be set to lengthen cooling cycles while the room is occupied or unoccupied. This passes more air through the unit while the coil is below the dew point, increasing the amount of moisture removed.

The wall sleeve amana ws900e is available for $95.00.
