851038

The Greenheck 851038 Limit Switch Kit is designed for use with Greenheck GDV, GDC, and GVCD variable air volume (VAV) boxes. This kit includes all necessary components to install and operate a limit switch, ensuring proper temperature control and energy efficiency in HVAC systems.

The kit includes a limit switch assembly, a wiring harness, and a mounting plate. The limit switch assembly consists of a temperature sensor and a mechanical limit switch. The temperature sensor is designed to detect the air temperature and activate the limit switch when the temperature reaches the set point. The mechanical limit switch, in turn, sends a signal to the control system to activate the fan or damper actuator when the temperature is reached.

The wiring harness in the Greenheck 851038 Limit Switch Kit is pre-wired with color-coded wires for easy identification and installation. The harness includes wires for power, sensor, and switch outputs, making it compatible with most HVAC control systems. The mounting plate is designed to be easily attached to the VAV box using the included hardware, allowing for secure and stable installation of the limit switch assembly.

The Greenheck 851038 Limit Switch Kit is made with high-quality materials and components, ensuring durability and reliability in demanding HVAC applications. The temperature sensor is precision-calibrated to provide accurate temperature readings, while the mechanical limit switch is designed to last for thousands of cycles. The wiring harness is made with insulated, stranded wires, and the mounting plate is made with heavy-duty aluminum for added strength and durability.

The Greenheck 851038 Limit Switch Kit is easy to install, with clear instructions and diagrams provided in the user manual. The kit is also backed by Greenheck's industry-leading warranty, giving customers peace of mind and confidence in their purchase. Overall, the Greenheck 851038 Limit Switch Kit is an essential component for any HVAC system that requires temperature control and energy efficiency, providing reliable and accurate operation for years to come.

The Greenheck 851038 Limit Switch Kit is designed to be used with Greenheck's line of VFD (Variable Frequency Drive) controlled ventilation fans. Here are some potential pros and cons of purchasing this limit switch kit:

1. Energy Savings: By using a variable frequency drive, the fan speed can be adjusted to meet the requirements of the space, rather than running at full speed all the time. This results in energy savings and a quieter operation. The limit switch kit allows for the fan to stop when the desired temperature or humidity level is reached, further contributing to energy savings.

2. Customizable: The limit switch kit is adjustable, allowing users to set the temperature or humidity levels that trigger the fan to turn on or off. This provides greater control over the ventilation system and can help maintain ideal conditions in the space.

3. Durable: Greenheck is known for manufacturing high-quality HVAC equipment, and this limit switch kit is no exception. It is constructed of heavy-duty materials and is designed to withstand the demands of commercial and industrial applications.

1. Cost: The Greenheck 851038 Limit Switch Kit may be more expensive than some other limit switch options on the market. However, the energy savings and customizability may outweigh the initial investment.

2. Compatibility: This limit switch kit is only compatible with Greenheck VFD-controlled ventilation fans. If you do not currently have a Greenheck fan or are not planning to purchase one, this kit may not be the best option for you.

3. Installation: Installing the limit switch kit may require some technical expertise, as it involves working with electrical and HVAC systems. It may be necessary to hire a professional installer to ensure proper installation and operation.

In conclusion, the Greenheck 851038 Limit Switch Kit offers energy savings, customizability, and durability, but it may come with a higher cost and compatibility limitations. If you currently have a Greenheck VFD-controlled ventilation fan and are looking to upgrade or optimize your system, this limit switch kit could be a worthwhile investment. If you do not currently have a Greenheck fan or are not planning to purchase one, you may want to consider other limit switch options that are more universally compatible.
