This non-programmable thermostat is designed to offer precise temperature control in residential and light commercial applications, providing comfort and energy savings effortlessly. Equipped with advanced TPI (Time Proportional Integral) control technology, this thermostat automatically adjusts to heating needs, ensuring efficient performance.

Applications:

The DT90A1008 is suitable for controlling conventional heating systems, such as boilers, radiators, and heat pumps. Its simplified design makes it an excellent choice for those seeking reliable and straightforward control without the complexity of programmable thermostats. It is perfect for homes as well as small offices or commercial premises that require consistent and efficient temperature control.

Main Features:

• Self-learning TPI Control: This thermostat uses a Fuzzy Logic TPI algorithm, which automatically adjusts the heating on and off cycle to maintain a stable and constant temperature. As the thermostat "learns" the characteristics of the installation, it improves the heating system's efficiency, reducing energy consumption.
• Frost Protection: The DT90A1008 includes a frost protection mode, ensuring the temperature does not drop below a critical level, protecting both the heating system and pipes from potential damage caused by extremely low temperatures.
• Adjustable Proportional Band: This feature allows adjusting the thermostat's response according to the specific needs of the heating system, providing more precise and adaptable control.

Technical Specifications:

• Power Supply: The thermostat operates with 2 AA alkaline batteries (IEC LR6) of 1.5 V, ensuring easy installation without the need for complex electrical connections. The estimated battery life is between 2 and 4 years, depending on usage and heating system conditions. Additionally, the thermostat features a low battery indicator to alert the user when replacements are needed.
• Self-learning TPI Logic: The self-learning TPI algorithm automatically adjusts the system's on and off cycles to maintain a stable temperature, avoiding sudden heat fluctuations and ensuring greater comfort and energy savings.
• Temperature Adjustment Range: The thermostat offers flexible temperature control with adjustable setpoint limits, allowing the user to set an appropriate temperature range for their needs.
• Battery Durability: With a lifespan of between 2 and 4 years, the use of AA batteries offers minimal maintenance and uninterrupted operation over extended periods.
