The operating condition detection means detects operating conditions of an operation lever.

A method of detecting and diagnosing operating conditions for a heat pump water heating system includes the steps of monitoring system operating conditions and comparing actual operating conditions to predicted operating conditions.

Operation conditions are as follows

The operating conditions include operating temperature, supply voltage, and operating frequency.

The following engine operating conditions shall be excluded from testing

The following engine operating conditions shall be excluded from testing

Preferably, a controller monitors operating conditions of the system and automatically releases the cooling plug based on the monitored operating conditions.

The operating conditions are collated into operating instructions associated with the predetermined types of activation.

CO emissions shall be measured at the following operating conditions

PM emissions shall be measured at the following operating conditions

The one or more current operating conditions can be compared to one or more previous operating conditions of the offset correlation.

A plurality of sensors sense the operating conditions and send the sensed conditions to a processor.

Operational conditions suitable for the respective access operations are selected.

The comparator may be calibrated for normal operating conditions.

Sub-assemblies of this type achieve excellent machine efficiency under the aforementioned operating conditions.
