The Tech controller ST-294V1 is a two-state room regulator designed to maintain a set temperature in an apartment by controlling a heating device. This controller is suitable for various types of furnaces, including gas, oil, and electrical furnaces, as well as boiler controllers. It ensures precise temperature control with an accuracy of ±0.1°C.

Key Features

• Temperature Control: The ST-294V1 maintains the set temperature by sending a signal to the heating device through an opening contact. This ensures that the room is heated to the required temperature efficiently.
• Hysteresis Range: The controller operates within a hysteresis range of 0.2 to 8°C, which allows for a comfortable temperature margin to prevent frequent on/off cycles.
• Key Lock Functionality: The device features a key lock function, allowing users to secure the settings and prevent accidental changes. The key lock can be activated using the menu options.
• Display and Interface: The controller is equipped with an LCD display, providing clear and easy-to-read information about the current temperature settings.
• Power Supply: The ST-294V1 operates using two AAA batteries, which provide reliable power without the need for a constant voltage supply.
• Relay Specifications: The controller includes a non-voltage NO/COM/NC relay with a maximum current rating of 1A at 230V AC, ensuring safe and efficient operation of the heating device.

With its compact design, easy installation, and user-friendly operation, the ST-294V1 is an excellent choice for maintaining a comfortable indoor climate.
