A.6 Unit Features
This Premium unit 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 Premium 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 kind 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 section M.2, 6-Status LED Indicator Definitions for further details.
Memory–Your Premium 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-The unit has 2 fan motors. The outdoor fan motor will run at minimum speed for 10 seconds before the compressor
start to reduce any compressor starting noise.
Random Compressor Restart-To help prevent power surges after a power outage (from many of your PTACS starting at the same
time), the compressor is equipped with a 2:45 to 3:15 random restart delay feature. Whenever the unit is plugged in, or power has been
restarted, a random compressor restart will occur.
Compressor Protection-To prevent short cycling of the compressor and maximize it's life, there is a random start-up delay of 3
minutes on the compressor and a minimum compressor run time of 3 minutes.
