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.
On-board Energy Management System
° Amana brand units are equipped with EMS technology to better control room temperature and save energy dollars.
DigiSmart Control Board
° Ready for wireless or wired operation
Programmable Set-back Program
° Owner-controlled settings allows automatic temperature setback when unit is idle.
Network Ready
° Amana brand DigiSmart units connected to a Tridium JACE controller automatically build their own wireless network.
DigiSmart Suite of Peripherals
° Remote occupancy sensor, remote thermostat, RF antennas, and RF platform controller provide everything you need to reduce energy costs by 35%.
DigiSmart In-Room Products
° 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.
DigiSmart Property-Wide Network
° The Tridium Jace controller connects all Amana DigiSmart PTACs in a property automatically through a self-detection routine.
° Once connected to your PC, the status and operating condition of each unit can be viewed remotely and settings changed centrally.
° The Tridium Jace controller through its NiagaraAX protocol has already built connections to more than 100 commercially available building management systems.
° 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.
° Unit Diagnostics - when switched to diagnostics mode, the unit shows ten different self-diagnosis codes to help keep the unit running most efficiently.
° Freeze Protection - when the unit senses temperature of 40°F or below, the unit automatically activates the fan motor and the electric or hydronic heat to help prevent burst water pipes or broken fixtures caused by freezing temperatures.
° Extended Heating with the Heat Pump - heat pump models will operate in heat-pump mode with external temperatures as low as 24°F to provide additional energy savings.
° 30 Second Fan-Only Delay - the fan continues to run for 30 seconds after the compressor has stopped or after electric heat has been turned off. This improves efficiency by dispersing the cooled or heated air still on the coil into the room.
