climate and housing stock it applies. KEEA further comments that the 40% over-sizing assumed for air-source heat pumps is likely inaccurate because heat pumps are typically sized for cooling, and the remaining heating capacity is covered by auxiliary heat. KEEA also recommends that the measure description make it clear that only programmable thermostats that are intended for use with heat pumps should be included, since conventional programmable thermostats can increase auxiliary heating use in heat pump homes. PECO agrees that language should be added limiting programmable thermostats to electric resistance heating and direct expansion (DX) cooling systems, as standard programmable thermostats could have negative energy consequences when installed on a heat pump system. PECO also recommends waiting for the completion of an Illinois programmable thermostat study, which has recently been proposed, before making any changes to this section of the TRM. PECO further recommends that the heating EFLH for Philadelphia should be 1,060. b. Disposition The Commission agrees with PECO regarding the algorithm used in this section, as it is relatively simple and consistent with various other HVAC-related TRM sections. As such, we deny KEEA’s request to utilize billing analysis data. The Commission agrees that the programmable thermostat study being performed in Illinois should be reviewed prior to making any changes to citations and values in this TRM section. The Commission also agrees with both KEEA and PECO that language should be added to this TRM section limiting programmable thermostats to electric resistance heating and DX cooling systems, as installing a programmable thermostat on a heat pump may have negative energy consequences. The TRM has been updated accordingly. The Commission agrees with PECO that the heating EFLH for Philadelphia
September 9, 2012, and that the reference to the ENERGY STAR website should be updated to reflect this date. PECO recommends that the TRM reflect the qualification that limits the scope of Version 6.0 to a product with a diagonal screen size of 15 inches or greater. PECO further recommends that in Table 2-74 the term PON_MAX be used instead of PMAX, with PON_MAX defined as the maximum allowable On Mode power consumption in watts. b. Disposition The Commission agrees with the PPL and PECO comments to revise references to Versions 4.1 or 5.1 of the ENERGY STAR Program Requirements for Televisions to Version 5.3 in the footer, Table 2-76 and Table 2-77. The TRM has been updated accordingly. The Commission agrees with PECO’s recommendation to use the terms “On Mode” and “Sleep Mode” in order to be consistent with the terms in Version 5.3 of the ENERGY STAR Program Requirements. We, however, retained in the protocol terms “Active Mode” and “Standby Mode,” in order to be consistent with language in prior TRMs and because the definitions of the terms “On Mode” and “Sleep Mode” in the Version 5.3 Program Requirements list “Active Mode” and “Standby Mode” as respective alternate names. The Commission rejects PECO’s request to update the date the ENERGY STAR website was accessed and to include language to indicate that Version 6.0 of the ENERGY STAR Program Requirements for Televisions limits eligibility to televisions with a diagonal screen size of 15 inches or greater. Version 6.0 was not finalized and released until shortly before the Tentative Order was adopted and, therefore, time did not allow for inclusion of the Version 6.0 eligibility criteria in the proposed TRM.
