Terminal Unit

Control (TUC)

Note: The auxiliary electric heat option is not available with a four-pipe fan-coil unit.

Fresh Air Damper Options

Manual

Units with manual fresh air dampers ship with the damper in the closed position, which is adjustable from zero to 100 percent in 25 percent incre- ments. To adjust the position, first remove the air filter to expose the damper stop screw on the control panel end. Relo- cate the stop screw to the appropriate position. Then loosen the stop screw wingnut and adjust the linkage. See Figure 30.

Figure 30. Re-locate the damper stop screw to adjust the damper position. The factory positions the stop screw in the 25% open position.

Auto 2-Position

Economizer

Units with an auto 2-position fresh air damper ship with a stop screw in the 25 percent reference position. The auto damper is adjustable to open from zero to 50 percent in 25 percent increments. To adjust the damper position, remove the air filter to expose the damper stop screw on the control panel end. Then relocate the stop screw to the appropriate position. See Figure 30.

Note: The open position of the damper does not correspond to the amount of fresh air. It is the installer’s responsibility to ensure that the building’s minimum fresh air requirements are met while taking necessary precautions to protect the unit during freeze conditions.

The economizer damper option contains a modulating, 3-wire floating point actuator and a damper assembly. The factory sets the damper at a minimum 25 percent open position by configuring the TUC. This setting is adjustable and can be changed in the field with EveryWareä software or Tracerâ. The minimum open position is adjustable from zero to 100 percent in one percent increments.

The economizer fresh air damper is controlled to the minimum position, which the factory configures. During the occupied mode, economizing is enabled and the fresh air temperature is measured while economizing.

Economizing is enabled within the TUC configuration based on an editable temperature differential between the fresh air temperature and the zone temperature. The unit will go into economizing mode when

LO specifications

Trane LO is a cutting-edge solution in the HVAC sector, designed with advanced engineering and smart technologies to meet diverse climate control needs. Renowned for its reliability and efficiency, Trane LO offers a wide array of features that set it apart in the market.

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.
