Pressure Switch

A high pressure switch is provided to protect the compressor against exces- sive refrigeration pressure. The low pressure switch should be wired in ac- cordance with the type of freezestat that is used. Trane factory supplies two low pressure switches in the re- frigerant circuit. The electrical con- nection is dependant upon which freezestat (35 or 20 degree) is selected The pressure switch is used to protect the compressor against operation un-

der low charge or catastrophic loss of charge situations.

The low water temperature switch is provided to protect the water-to-re- frigerant heat exchanger from freez- ing. This device triggers the lock out relay when leaving water temperatures fall below the preset freezestat setting. This device may be reset by cycling power, but the system should be re- viewed for operational error.

Important Notice

The low pressure switch should be wired to activate at refrigerant pressures of 35 psig when a 35 degree F freezestat is used; 7 psig when a 20 degree F freezestat is used. The installer should verify that the correct freezestat and low pressure switch are used in your application. Misapplication can produce a failure to the unit and cause the warranty to be voided.

GSSD specifications

The Trane GSSD (Ground Source, Self-Contained Direct) is an advanced geothermal heat pump system designed to provide efficient heating and cooling solutions for residential and commercial applications. Leveraging innovative technology, the GSSD utilizes the earth's natural energy to deliver optimal indoor comfort while maintaining a low environmental footprint.

One of the main features of the Trane GSSD is its integrated design, which combines multiple components into a self-contained unit. This simplifies installation and reduces the complexity typically associated with traditional heating and cooling systems. The GSSD is available in various sizes and configurations, making it suitable for a wide range of applications, from single-family homes to large commercial buildings.

The GSSD employs a closed-loop geothermal system that circulates a fluid through underground pipes to exchange heat with the earth. This method allows the unit to draw heat from the ground in the winter and dissipate heat back into the earth during the summer months. The system operates using a heat pump, which efficiently transfers thermal energy, providing consistent indoor temperatures throughout the year.

Key technologies incorporated into the Trane GSSD include variable speed compressors, which enable the unit to adjust its output based on the heating or cooling demand of the space. This leads to improved energy efficiency and reduced operational costs. Additionally, the system employs advanced controls and smart technology that enable remote monitoring and adjustments, ensuring optimal performance at all times.

Another significant characteristic of the GSSD is its environmentally friendly operation. By utilizing renewable energy from the ground, the system significantly reduces greenhouse gas emissions compared to conventional fossil fuel systems. Furthermore, the GSSD is designed for quiet operation, minimizing noise pollution and enhancing occupant comfort.

In summary, the Trane GSSD represents a cutting-edge solution in the realm of geothermal heating and cooling systems. Its self-contained design, advanced technologies, and commitment to sustainability make it an ideal choice for those seeking energy-efficient climate control options. With its unique combination of features and capabilities, the GSSD meets the demands of modern applications while contributing to a greener future.
