主权项 1. A method of operating a laundry treating appliance comprising a treating chamber for receiving laundry to be treated according to an automatic cycle of operation, hot and cold water supplies, and a supply conduit fluidly coupling the hot and cold water supplies to the treating chamber through a chemistry dispenser, the method comprising: alternating supplying of water from the hot and cold water supplies through the chemistry dispenser of the supply conduit to the treating chamber to form a mixture of hot and cold water in the treating chamber, the mixture having a predetermined set temperature; sensing a temperature of the supply conduit upstream of the chemistry dispenser during the alternating supplying; switching from the cold water supply to the hot water supply when the sensed temperature satisfies a low temperature limit (LTL); switching from the hot water supply to the cold water supply when the sensed temperature satisfies a high temperature limit (HTL); sensing an ambient air temperature; and increasing the LTL and the HTL from respective pre-defined values when the sensed ambient air temperature exceeds a temperature threshold.
