UNIT FEATURES
This ETAC II has many exciting features which are different than those found on standard PTAC
models. The owner must be familiar with these features in order to fully understand the operation
and capability of the unit.
• Intelligence
– Your ETAC II unit has an on board computer that utilizes real time diagnostics
to prolong the life of your unit. There is an LED indicator on the control board, behind the front
panel, that will flash an error code if the unit has detected some type of fault condition. In
many cases, the unit will automatically clear the fault condition and continue operating with
no interruption. In some cases, the condition cannot be cleared and the unit will require service.
In those cases, an “Fx” failure mode will be displayed on the digital display. For a detailed list
of all error codes and “Fx” conditions, see Intelligent Self Checking and Control section on page
20 for further details.
• Memory
– Your ETAC II unit also has memory. If power is lost, all of the control settings (set-
point, mode, fan speed, on/off and configuration) are remembered. So when power is restored,
the unit will start back up in the mode (and configuration) it was in, when power was lost.
•
Premium Sound
– Your Premium ETAC II is also the quietest Gree PTAC. Not only does it have
2 fan motors and a tangential blower wheel for optimum sound, the indoor fan will always run
a minimum of 10 seconds before the compressor, to help reduce any compressor starting noise.
• Random Compressor Restart
– To help prevent power surges after a power outage (from
many of your ETAC IIs starting at the same time), the compressor is equipped with a 165 to
195 second random restart delay feature. Whenever the unit is plugged in, or power has been
restarted, a random compressor restart will occur.
• Dry Mode
– will help to manage and reduce the humidity in the room, making it more
comfortable. In DRY mode, the unit will modulate cooling mode at low fan speed until the
room temperature is 4 deg. F below the room temperature setting regardless of fan mode
selection. Dry mode should not be considered a substitute for a stand alone dehumidifier.
• Compressor Protection
– To prevent short cycling of the compressor and maximize its life,
there is a 3 minute start-up delay on the compressor after power up and between operating
cycles and a minimum compressor run time of 3 minutes.
