Smart Wi-Fi Thermostat for Android & iOS Users

The RET001, RET002, RET003, and RET004 Universal Thermostats offer a range of features and functionalities to suit diverse heating and cooling needs. These programmable thermostats provide precise temperature control, allowing users to stay comfortable throughout the year.

The thermostats are compatible with a variety of HVAC systems, including oil furnaces, and can be operated in 1-stage cooling and 1-stage heating modes with separate heating and cooling swing (cycle rate) adjustments. However, they are not compatible with heat pump systems that have auxiliary or emergency heating, RV thermostats, or multi-stage systems.

One of the key features of these thermostats is their large, backlit LCD displays, which measure approximately 6.8 square inches. This allows users to easily view the current temperature, set temperature, and other important information from a distance. The intuitive button controls make it simple to adjust the temperature, fan settings, system mode, and hold cool/heat mode.

The thermostats offer weekly programming capabilities, with seven-day schedules and four time periods per day. Users can easily set the start times and target temperatures for each period, ensuring optimal comfort and energy efficiency.

For enhanced convenience, the RET003 and RET004 models feature Wi-Fi connectivity, allowing users to connect the thermostat to their smartphones via the Smart Life app. This enables remote control and monitoring of the HVAC system, providing flexibility and accessibility from anywhere.

The thermostats are powered by either 2 AAA batteries (RET001 and RET002) or 24V (RET003 and RET004). When the battery voltage symbol flashes, it indicates that the batteries need to be replaced.

It is important to note that these thermostats are not compatible with 110-240V HVAC systems, such as substrate heating or line voltage systems. Customers are advised to carefully check the wiring ports of their old thermostat to ensure compatibility before purchase.

For optimal installation, it is recommended to have a professional installer handle the process unless the user has a strong technical background. Failure to follow the installation instructions correctly may result in serious material damage.

These universal thermostats are suitable for a wide range of applications, including hotels, guesthouses, homes, offices, and various types of commercial establishments. They are backed by excellent quality and after-sales service, with a package that includes the thermostat, user manual, and mounting hardware.

In summary, the RET001, RET002, RET003, and RET004 Universal Thermostats offer precise temperature control, user-friendly features, and compatibility with a variety of HVAC systems, making them a versatile choice for maintaining comfort and energy efficiency in various indoor environments.
