Wiring

All sensor and input circuits are normally at or near ground (common) potential. When wiring sensors and other input devices to the Tracer® ZN.010, ZN.510, ZN.520 or TUC, avoid creating ground loops with grounded conductors external to the unit control circuit. Ground loops can affect the measurement accuracy of the controller.

!CAUTION: Unit transformer IT1 provides power to fan-coil unit only. Field connections to the transformer IT1 may create immediate or premature unit component failure.

All input/output circuits (except isolated relay contacts and optically isolated inputs) assume a grounded source, either a ground wire at the supply transformer to control panel chassis, or an installer supplied ground.

Note: Do not connect any sensor or input circuit to an external ground connection.

The installer must provide interconnection wiring to connect wall mounted devices such as a fan mode switch or zone sensor module. Refer to the unit wiring schematic for specific wiring details and point- to-point wiring connections. Dashed lines indicate field wiring on the unit wiring schematics. All interconnection wiring must conform to NEC Class 2 wiring requirements and any state and local require- ments. Refer to Table 3 for the wire size range and maximum wiring distance for each device.

Recommendation: Do not bundle or run interconnection wiring in parallel with or in the same conduit with any high-voltage wires (110V or greater). Exposure of interconnection wiring to high voltage wiring, inductive loads, or RF transmitters may cause radio frequency interference (RFI). In addition, improper separation may cause electrical noise problems. Therefore, use shielded wire (Beldon 83559/83562 or equivalent) in applications that require a high degree of noise immunity. Connect the shield to the chassis ground and tape at the other end.

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.
