Installation (continued)

4. Install and Wire the Discharge Air Temperature Sensor

CAUTION

As with any mechanical equipment, personal injury can result from contact with sharp sheet metal edges. Be careful when you handle this equipment.

CAUTION

Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at disconnect switch.

The tip of the sensor must be located in a region of fully mixed supply of air before the take-offs (not in a dead air space) in order for the system to work correctly.

a. Wire discharge air temperature probe to control panel using thermostat wire. Note that the temperature sensor is not polarity sensitive.

b. Be sure that the tip of the sensor is located at least 15 inches downstream from the leaving air side of the evaporator in the discharge plenum, and 1/3 of the depth (D/3) of the plenum (D) from the front of the plenum (the front is the side with the furnace or CB access doors), and centered side to side. Move the adjustable bracket along the length of the discharge air sensor to achieve proper sensor tip location (tip of sensor to be located at W ÷ 2). The sensor can be inserted from any side of the plenum, as long as the tip of the sensor is in the correct position. See Figure 3.

IMPORTANT: The discharge air sensor is required. If a short or open circuit is detected between the Plenum Sensor terminals, the control panel will only respond to Zone 1 and the dampers will stay in the open position.

Zone Control Panel, LZP-2 specifications

Lennox International Inc, a leader in the HVAC industry, has made significant strides in advancing climate control technologies, particularly with their innovative HVAC Zone Control System, designated LZP-2. This system is designed to provide enhanced comfort and energy efficiency in residential and commercial settings by allowing for precise temperature control across different zones within a building.

One of the main features of the LZP-2 HVAC Zone Control System is its ability to operate multiple zones independently. This zoning capability means that different rooms or areas can be set to different temperatures based on usage patterns or individual preferences. Homeowners can enjoy a cooler environment in living spaces while maintaining a warmer temperature in less frequently used zones, such as guest rooms or basements. This tailored approach not only improves comfort but also leads to significant energy savings.

Another key characteristic of the LZP-2 is its smart technology integration. The system can be connected to a comprehensive home automation network, allowing users to manage their HVAC settings remotely. With mobile applications, users can adjust their zone temperatures from anywhere, ensuring optimal comfort when they return home. Integration with smart thermostats also enables the LZP-2 to learn household occupancy patterns, optimizing heating and cooling schedules for maximum efficiency.

The LZP-2 also employs advanced sensor technology to monitor temperature and airflow in various zones. These sensors provide real-time data, enabling the system to make adjustments to maintain desired conditions effectively. This responsiveness not only ensures comfort but also prevents energy waste, leading to reduced utility bills.

In terms of installation and operation, the LZP-2 is designed for user-friendly implementation. Compatible with most HVAC systems, the zoning panel can be integrated seamlessly during the initial setup or retrofitted into existing systems. The modular design allows for expansion, meaning additional zones can be added as needed without significant disruptions.

Lastly, the LZP-2 HVAC Zone Control System is backed by Lennox's longstanding reputation for quality and reliability. With robust build quality and excellent customer support, users can be assured of a dependable solution for their climate control needs.

In summary, the Lennox LZP-2 HVAC Zone Control System represents a significant leap forward in home and commercial climate management, combining advanced zoning capabilities, smart technology, and user-friendly design to create a superior indoor environment with enhanced energy efficiency.
