1. Automatic Setup Capabilities
a. Which of the following capabilities does the system, consisting of the main unit and a
paired thermostat or controller, offer to ensure a quality installation? (check all that
apply)
System measures and self-verifies that the refrigerant charge is within
manufacturer tolerances.
System measures and displays airflow and verifies that it is within OEM settings
or measures and displays external static pressure and fan speed settings.
System measures and reports the watt draw of the blower fan.
System provides an easily accessible test mode that locks the system into the
highest fan speed and compressor capacity settings available such that
refrigerant charge, airflow or external static pressure, and blower fan watt draw
can be measured by the technician.
System automatically discovers/recognizes compatible communicating outdoor
and indoor units.
System automatically discovers/recognizes communicating humidifiers and
dehumidifiers.
System automatically prompts the installer to run preconfigured system tests
