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. Heat and moisture inside are removed when warm air passes over the cool indoor coil. The heat and humidity in the air are removed by the coil, thereby "cooling" the air indoors.
When the PTAC operates in the heating mode, the unit operates in reverse. 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.
Indoor comfort all year - 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.
Simple Installation - 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.
Independent Operation - 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.
On-Board Energy Management System (EMS)
Set-Back Mode
The owner can determine amount of time unit is left 'untouched' (buttons not pushed) before the PTAC begins a set-back routine and new thermostat temperature takes effect.
All set-back routines can be changed 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 sensors show an outdoor 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 24°F to provide additional energy savings.
30-Second Fan-Off 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.

Automatic Network Setup
The DigiSmart RF network automatically configures and heals itself.
No need to log unit on or off the network.
High-Capacity Network
DigiSmart runs independently on each PTAC or up to 170 units in a single network installation
Set-Back Mode
The owner can determine amount of time unit is left 'untouched' (buttons not pushed) before the PTAC begins a set-back routine and new thermostat temperature takes effect.
All set-back routines can be changed by owner.
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.
Maintenance Status
Separate green LED indicator light to show if unit requires Maintenance at the unit level.
Network interface shows status of each PTAC and peripheral (thermostat or sensor)
Unit Diagnostics
When switched to diagnostics mode, the unit shows ten different self-diagnosis codes to help keep the unit running most efficiently.
Email Notification
Once linked to a PC, the DigiSmart network can automatically send an e-mail to notify a property of maintenance issues.
Energy Management System (EMS) software
Is written in 'flash' memory in the control board and not 'hard coded'.
That means EMS software can be updated at the PTAC or through the DigiSmart network without needed to visit each unit.
