A method for operating a water cooler, wherein the water cooler includes a cooling system, a storage compartment assembly, a water dispenser assembly, and a climate control assembly including a thermostat and a control capillary, includes coupling the control capillary to the thermostat, and coupling the thermostat to the cooling system such that the thermostat controls the operational state of the cooling system. The method includes positioning the control capillary adjacent each of the storage compartment assembly and the water dispenser assembly, determining the temperature of the storage compartment assembly and the water dispenser assembly using the control capillary, and cooling the storage compartment assembly and the water dispenser assembly using the cooling system.
