PROBLEM TO BE SOLVED: To provide a heat medium supply system capable of improving usability by easily adjusting the heating output of a heating terminal. SOLUTION: A manual operation-type opening and closing ratio setting means A for selecting and setting one of opening and closing ratios of plural stages determined in a configuration of varying requested heat quantities, as a target opening and closing ratio for periodically opening and closing an opening and closing means 58 for intermittently supplying a heat medium from a heat source means 4 to the heating terminal 2, is constituted to determine the opening and closing ratio in a state that the smaller the requested heat quantity is, the smaller a variation width between the adjacent opening and closing ratios of plural stages arranged in the variation direction of the requested heat quantities, with respect to the opening and closing ratios having the same heat medium temperature, as the opening and closing ratios of plural stages determined in the configuration of varying the requested heat quantity.
