Using Tracer Summit®

Unit Mode Listed as Standby

Remove the 24 VAC power from the board and then reapply it to cycle the unit through a power-up sequence. By default, the controller attempts to reset all diagnostics at power-up.

The TUC editor’s reset failure point allows the user to reset controller diagnostics. Also, Tracer® versions 14.4 and higher provide a “+ enter” option from the TUC service summary screens that allow latching diagnostic reset.

When using a Tracer Summit® system, reset the unit diagnostics with the reset diagnostics button on the TUC editor screen.

The unit’s operating machine state is in standby when one of the following conditions occurs:

1.Tracer® override is present.

2.During the power-up sequence or any time when the TUC is calibrating its end devices.

3.When the TUC is in the unoccupied mode and there is no call for heating or cooling.

4.In the occupied mode when the desired capacity is unavailable.

ie: the TUC requests a 2-pipe unit to heat, yet no hot water or electric heat is available. The TUC will list the unit as being in standby mode.

One of the core characteristics of Trane LO is its energy efficiency. Equipped with variable speed compressors, the system can adjust its output according to the cooling or heating demand, ensuring optimal energy use. This feature not only reduces energy consumption but also lowers utility bills for users. Additionally, Trane LO units often come with a SEER (Seasonal Energy Efficiency Ratio) rating that ensures top performance during hotter months.

Incorporating state-of-the-art technology, Trane LO features Smart Technology integration. Through IoT (Internet of Things) capabilities, users can monitor and control their HVAC systems remotely via smartphones or smart home devices. This feature promotes convenience and ensures that energy use can be optimized from anywhere, giving users greater control over their indoor climate.

Another standout technology in Trane LO is its use of environmentally friendly refrigerants. The system is designed to utilize low-GWP (Global Warming Potential) refrigerants, making it compliant with modern environmental standards and contributing to a greener planet.

The Trane LO also emphasizes durability. Constructed with high-quality materials, including weather-resistant finishes, these units are built to withstand various environmental conditions, ensuring they maintain peak performance over the years.

Noise reduction is another critical aspect of the Trane LO line. With features such as sound blankets and vibration dampening technology, the units operate quietly, ensuring that the comfort of users is not compromised by disruptive noise levels.

Maintenance is simplified with the Trane LO, as several units are engineered for easy access to essential components, promoting hassle-free servicing. This is vital for prolonging the lifespan of the system and reducing maintenance costs.

In summary, Trane LO represents a fusion of energy efficiency, advanced technology, environmental responsibility, durability, and user-friendly features. Whether for residential or commercial applications, Trane LO systems stand as a reliable choice for effective climate control.
