Technological innovations have delivered heat pump control systems that rely on a Wi-Fi connection to operate with the greatest efficiency. Smart controllers are only capable of operating at peak performance when connected to a Wi-Fi network, which is why Energy Trust requires that they be connected in its 2025 Specifications Manual.
Smart thermostats combined with any heat pump system must be connected to the internet, as stated in the 2025 Specifications Manual under HEAT PUMP CONTROLS: HC 1.0: Introduction. The manual states, “The outdoor air temperature shall be determined either by a locally installed outdoor temperature sensor or by online weather data. If the heat pump control utilizes online weather data, the unit shall be connected to the home’s internet and, if applicable, the thermostat must be registered.“
Ensuring smart thermostat connectivity helps ensure that your customers receive the most benefits from their heat pumps and smart thermostats. Here are three reasons a Wi-Fi connection is so important:
- Smart controllers access current local weather data from web-based weather stations
- Mobile apps allow remote access for users, including remote monitoring and control
- Operating system updates, which keep smart thermostats running correctly, require a Wi-Fi connection
Installer setup requirements for smart thermostats can be time-consuming and daunting, but it’s critical to complete every step for the system to perform as efficiently as possible. With the flood of new smart controller models coming out and the rising popularity of wireless technology, continuing education on proper installation is paramount. Energy Trust recommends that trade allies review and educate their workforce on the importance of connectivity when installing smart thermostats to avoid callbacks and incentive payment delays.
