Summary

Introduction and Overview of Sensi Thermostats

In this episode, Brian Orr hosts Tom Lorenz, who leads Sensi's traditional and smart thermostat lines at Copeland. They discuss features, particularly the auxiliary lockout and balance point settings in heat pump thermostats, emphasizing the importance of understanding these features for optimal energy efficiency.

Understanding Auxiliary Lockout

The auxiliary lockout feature is crucial for maintaining energy efficiency, as auxiliary heat can be more costly than heat pump operation. Tom explains that all Sensi thermostats now include this feature, utilizing either internet weather data or a physical outdoor sensor to determine when to engage auxiliary heat, thereby preventing unnecessary energy expenditure.

The Complexity of Balance Point

Balance point settings are not straightforward; they vary significantly based on multiple factors including the efficiency of the heat pump, insulation of the home, local climate, and energy costs. Tom advises contractors to understand the specifics of the equipment and the secondary heat source to properly set these balances for optimal performance and comfort.

Sensi's Design Philosophy and User Experience

The discussion highlights Sensi's commitment to prioritizing user experience in thermostat design. Tom shares that Sensi focuses on the essential features to avoid complexity and user frustration. The Sensi app is noted for its intuitive design, enabling easy setup and remote control, which enhances the user experience.

Future Features and Contractor Education

Sensi aims to keep evolving with new features like wireless outdoor sensors and emphasizes the need for contractor education in proper thermostat setup. The hosts stress the importance of understanding equipment specifications to utilize thermostats effectively.

Show notes

In this informative episode of the HVAC School podcast, host Bryan Orr sits down with Tom Lorenz to talk about some of the Sensi thermostat features, particularly aux lockout and balance point. Tom leads the traditional and smart thermostat lines at Copeland and has over 25 years of experience in the industry.

The discussion focuses on two key features of heat pump thermostats: auxiliary lockout and balance point. Tom explains that auxiliary lockout is crucial for energy efficiency, as auxiliary heat (whether electric or propane) is typically more expensive than heat pump operation. All Sensi thermostats now include this feature, which can use internet weather data or a physical outdoor sensor to determine when to engage auxiliary heat.

Balance point settings are complex, and there's no one-size-fits-all approach. Factors like heat pump efficiency, home insulation, local climate, and energy costs all play a role in determining the ideal balance point. They emphasize the importance of contractors understanding the specific equipment and secondary heat source when setting up a system for optimal performance and efficiency.

The conversation also touches on Sensi's approach to thermostat design, prioritizing ease of use and essential features over feature bloat. Tom highlights Sensi's commitment to user testing and creating intuitive interfaces for both contractors and homeowners. The podcast concludes with resources for listeners to learn more about Sensi thermostats and advanced HVAC control strategies.
