GS Connect RTC is a software program that controls any type of geothermal system and is specifically designed for use in smaller building.

RTC uses reactive building controls to ensure that the system is operating according to the original design. These reactive controls are based on known temperature set points throughout the year. When RTC senses that the given set points will not be reached, it operates the auxiliary equipment to bring the system back within original design parameters.

RTC contemporaneously reduces energy consumption and maintains the health of the borefield. Specifically, the average entering water temperature in the heat pumps is reduced by 5+ degrees when using RTC. This reduction in temperature helps reduce compressor energy and increases lifespan of the equipment. Additionally, these reduced temperatures help keep the borefield healthy by maintaining its temperature within the original design.


  1. Easy to use interface – RTC is designed with a user-friendly interface. Customers can see real time data or generate graphs of tracked data.
  2. Data Tracking – RTC continuously tracks and stores information for future use.
  3. Automatic Controls – By providing controls for auxiliary equipment, RTC eliminates the need for in person temperature monitoring and manually controlling the valves. This helps reduce accidental freezing and/or wasted gas.
  4. Reactive Conditioning – RTC compares current loads against design loads. If the loads are outside of design bounds, RTC will help bring the system into design range.
  5. Reports – Greensleeves’ team of engineers can provide easy to understand reports with key information about the health and future needs of the geothermal system.
