About this episode
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.
