CONTROL WIRING

1 Typical 24-volt thermostat with subbase -2ET03700424 for manual changeover.

2 Only required on units with supplemental electric heat.

TO REMOTE SENSOR

2ET04701324 IF USED

Note: The thermostat terminals shown above are typical. Check thermostat and unit wiring diagrams for correct wiring connections.

1 Typical Electronic programmable thermostat 2ET04701124 with subbase for either manual or automatic changeover.

2Only required on units with economizer. Remove jumper L2 from terminals

4 and 9 on jumper plug P7. The outdoor air intake dampers will return to their fully closed position when the thermostat switches to the “unoccupied” mode.

3Second stage cooling may be used on units with economizer. Remove jumper J1 from terminals 8 and 10 on jumper plug connector P7.

B3CH 048 and 060 specifications

The York B3CH 048 and 060 are part of the advanced line of commercial rooftop units by York, known for their reliability and energy efficiency. Specifically designed for medium to large commercial applications, these units are engineered to provide optimal performance while minimizing operational costs.

One of the key features of the York B3CH series is its adaptable cooling capacity. The B3CH 048 has a cooling capacity of 48,000 BTU/h, while the B3CH 060 offers a slightly higher capacity of 60,000 BTU/h. This flexibility allows businesses to select the unit that best meets their specific cooling requirements, ensuring comfort and efficiency in any environment.

Both models utilize a highly efficient scroll compressor, which is known for its durability and quiet operation. The scroll compressor design allows for superior performance in varying load conditions, contributing to better energy efficiency. In addition, the units feature a multi-speed motor design that adjusts airflow based on demand, further enhancing performance and reducing energy consumption.

York has incorporated advanced technologies into the B3CH series to ensure reliability and ease of maintenance. These units come equipped with a smart control system that enhances user interface through advanced diagnostics and monitoring capabilities. The control system enables users to program temperature settings efficiently and oversees system operation to prevent potential issues. The built-in diagnostic features help facilitate quicker troubleshooting, minimizing downtime.

The units are designed with a robust and weather-resistant cabinet, ensuring durability in various environmental conditions. The galvanized steel construction aids in corrosion resistance, leading to a longer lifespan for the units. Additionally, both models are equipped with high-efficiency air filters that not only improve indoor air quality but also extend the life of the system by minimizing dust accumulation.

Energy efficiency is a significant consideration in today's commercial environments, and the York B3CH series excels in this aspect. With competitive SEER and EER ratings, these units not only comply with but often exceed industry standards, resulting in lower energy bills and reduced carbon footprints.

In summary, the York B3CH 048 and 060 are cutting-edge rooftop units that combine performance, reliability, and energy efficiency. They are ideal for businesses seeking effective solutions for climate control while maintaining operational and energy costs at a minimum.
