Abstract :In this study, it is aimed to save energy by placing timers in public offices and private workplaces for heating residential units with geothermal energy outside working hours and on holidays. For this, proportional valve control system design and application has been carried out. Proportional valve is connected to the heat exchanger return. The control form of the floating type proportional valve is on-off, the control of the proportional valve with analog input is applied in the form of PI control. It is realized by programming smart relays in both controls. PT100 was used to measure the heat exchanger inlet, return and temperature values entering the building. As a result of this study, the heat exchanger return temperature was adjusted to the temperature at which the buildings would not cool completely on holidays and after working hours, allowing more buildings to be heated with the energy saved.
