• Complexity and need for additional support and training to install more complex pump

systems such as those that include variable frequency drives.

• Higher upfront cost and only partial industry adoption of lifecycle cost analysis when

choosing a new or replacement pump as higher energy performance pumps and pump

systems are often more expensive to purchase but save money operationally.

• CEE Tier 1 is a performance level intended to enable sufficient product volume for

energy efficiency programs to achieve cumulative savings goals and to emphasize

significant per unit savings over the performance baseline, which is typically the

federal minimum efficiency standard.

• CEE Tier 2 or 3 provides significant per unit savings above and beyond the

preceding tier and reflects the performance of products already available from

numerous manufacturers. Though eligible products may be available at higher

price points, these performance tiers are intended to yield cost-effective energy

savings.

• A CEE Advanced Tier represents an aspirational level of efficiency and product

performance, agreed by manufacturers to be technically feasible. While few or no

products may fulfill the Advanced Tier's standards at the time it is created and

those that exist may not be appropriate for all applications, it lays the groundwork

for future programs, provides a longer-term focus and shared performance target

for manufacturers, and provides recognition for the first manufacturers to develop

products that achieve new heights of efficiency and performance.

- Manual speed controls: test both: (1) along the maximum speed circulator pump curve to achieve the test point flow rates as described in Recommendation #6B for the max speed input power values and (2) based on manual speed adjustment to the lowest speed setting that will achieve a head at or above the reference curve (in Recommendation #8), at the test point flow rates (in Recommendation #6B) for the reduced speed input power values.

- Pressure controls: test with automatic speed adjustment based on factory selected control setting or with manual speed adjustment or with simulated pressure signal to trace factory selected control curve setting that will achieve the test point flow rates (in Recommendation #6A) with a head at or above the reference curve described in Recommendation #8. Automatic speed adjusted controls may be manually adjusted to achieve 100% BEP flow and head point at max speed. For adaptive pressure controls, test at the minimum thresholds for head based on manufacturer literature through manual speed adjustment to achieve the test point flow rates (in Recommendation #6A) with head values at or above the reference curve (in Recommendation #8).

o Manufacturer is able to choose the factory control (curve) logic, when multiple options are available.

o Manufacturer will report the control (curve) setting used and method of control to DOE with certification reporting

- Temperature controls: test based on manual speed adjustment or with simulated temperature signal to activate the temperature-based control to achieve the test point flow rates (in Recommendation #6A) with a head at or above the reference curve described in Recommendation #8.

- External input signal control: test with a simulated signal both: (1) along the maximum speed circulator pump curve to achieve the test point flow rates as described in Recommendation #6B for the max speed input power values and (2) with speed adjustment using a simulated signal to the lowest speed setting that will achieve a head at or above the reference curve (in Recommendation #8), at the test point flow rates (in Recommendation #6B) for the reduced speed input power values. For circulators that only have an external input signal control and that cannot operate without an external input signal, test along the reference control curve (in Recommendation #8) to achieve the test point flow rates (in Recommendation #6B) with a head at or above the reference curve with the same weights as temperature- and pressure-based controls (in Recommendation #7).

- No manual speed controls, pressure controls, temperature controls, or external input signal controls: test along the maximum speed circulator pump curve to achieve the test point flow rates as described in Recommendation #6A

• Automatically terminates water circulation once hot water has reached the pump or desired fixture.

• Does not allow the pump to operate when the temperature in the pipe exceeds 104 °F or for more than 5 minutes continuously. The pump must not be capable of operating without the control without physically destructive modification of the unit, such as any modification that would violate the product’s standards listing.

individual have the requisite experience and knowledge to conduct pump system

assessments, and provide pump system optimization solutions. Individuals that pass the

exam can use the PSAP designation. The PSAP credential provides assurance to utilities and

others that the individual conducting measurement and verification for pumping system

energy efficiency measures has the required experience and knowledge. More information
