NOTE
The SmartPad™ is not equipped with a battery backup.
All set points, tuning values and ramping profiles are stored in non-volatile
memory and will be permanently stored in the SmartPad™.
If power is removed from the controller it will resume operation when
power is restored.
In Steady State set point mode the controller will resume operation at the
previous steady state set points.
In Programmable set point mode the controller will resume operation at
exactly the same segment and time remaining in that segment if the
duration of the power loss is less than approximately 20 minutes . If the
duration of the power loss exceeds approximately 30 minutes the
controller will re-initiate the program according to the loop parameters
defined in the
INIT screen.
Fault Displays
If the system encounters a temperature, low-water, remote on/off switch, or refrigerant
pressure fault, the system will shut down and the SmartPad™ will indicate the fault that
has occurred. The SmartPad™ will continue to indicate that the fault exists, and will
indicate if/when the fault has cleared.
If the fault has been cleared, the system can be re-energized by pressing the Standby key
. If the fault has not cleared, the source of the fault must be determined and corrected
before the system can be re-energized.
NOTE
Some faults will clear automatically and others will require user
intervention.
Regardless of the fault clearing mechanism, the user must press the Standby
key in order for the conditioner to resume operation.
