The ther-mostat shall initially be programmed by the manufacturerwith a heating temperature set point no higher than 70°F(21°C) and a cooling temperature set point no lower than78°F (26°C).

R403.1.2 Heat pump supplementary heat (Mandatory).Heat pumps having supplementary electric-resistance heatshall have controls that, except during defrost, preventsupplemental heat operation when the heat pump compres-sor can meet the heating load.

R403.2 Hot water boiler outdoor temperature setback.Hot water boilers that supply heat to the building throughone- or two-pipe heating systems shall have an outdoor set-back control that lowers the boiler water temperature basedon the outdoor temperature.

R403.3 Ducts. Ducts and air handlers shall be in accordancewith Sections R403.3.1 through R403.3.5.

R403.3.1 Insulation (Mandatory). Supply and returnducts outside of the building thermal envelope shall beinsulated to not less than R-8.
