TECH T-2.1 – Wired Two-State Room Thermostat

TECH T-2.1 is a reliable and easy-to-use wired two-state room thermostat designed to control a heating device. Its purpose is to maintain the set room temperature by sending a signal to the heating device.

The thermostat features a built-in air temperature and humidity sensor. The current temperature is continuously displayed on the screen, while the Menu button allows the display to be switched to the current humidity level.

Temperature and Humidity Measurement

TECH T-2.1 features a built-in temperature and air humidity sensor. In standby mode, the current room temperature is displayed. Pressing the Menu button allows the display to be switched to the current humidity level.

Set Temperature Adjustment

The set temperature can be changed directly on the thermostat using the < and > buttons. The room temperature setting range is 5°C–35°C.

Heating and Cooling Mode

The TECH T-2.1 thermostat allows the user to select between heating and cooling modes. The required operating mode can be selected in the thermostat menu.

Adjustable Hysteresis

The thermostat allows the room temperature hysteresis to be set within a range of 0.2°C–4°C. Hysteresis defines the tolerance around the set temperature and helps limit unnecessary switching caused by small temperature fluctuations.

Sensor Calibration

The calibration function allows the temperature sensor reading to be corrected within a range of -10°C to +10°C.

Automatic Button Lock

T-2.1 features an automatic button lock function. When activated, the buttons are automatically locked after several seconds of inactivity. The buttons can be unlocked by simultaneously pressing and holding the < and > buttons.

Set Temperature Limits

The thermostat allows the user to set minimum and maximum set temperature limits. This function defines the temperature range within which the user can adjust the set temperature.

Glass Panel and Wall Mounting

The thermostat features a glass panel and a housing designed for wall mounting. The device is available in two colour versions: white and black.

Technical Specifications

Application

TECH T-2.1 is designed to control a heating device and maintain the set room temperature. The thermostat can also operate in cooling mode. Thanks to the built-in temperature and humidity measurement, it allows the user to monitor the conditions in the room.

Does the TECH T-2.1 measure air humidity?

Yes. TECH T-2.1 features a built-in air humidity sensor and allows the current humidity level to be displayed on the thermostat screen. The humidity measurement range is 10–95% RH.
