Connecting the BiLux T26 thermostat (Imit Ta3). Turning on and off

Thermostats Italian company IMIT stamps TA3n And TA2n are used to regulate temperature in heating systems to maintain the most comfortable temperature indoors, as well as to save electrical energy used for heating at a time when there are no people in the room. For example, during working hours it is necessary to maintain a temperature of at least +20°C, and at night it is enough to maintain a temperature in the room of +7°C, which allows you to save half of the electrical energy, and therefore saves half of your heating money every day.

Brand thermostats TA3n are practical temperature control devices that are affordable for the consumer and provide high quality regulation.

Currently, TA2n thermostats (temperature regulators) have been discontinued and replaced with an improved model of the TA3n brand.
It inherited ease of use and reliability from the old model. The advanced control knob allows you to limit or fix the set temperature. The TA3n thermostats are available in four modifications to best suit the needs of the consumer: a version with a signal light, an ON/OFF switch or a WINTER/SUMMER switch, as well as without additional functions.

The operation of the TA3n thermostat is based on the expansion of saturated steam in a gas bellows.
Unlike similar devices, TA3n thermostats are highly reliable, because simple mechanical design is not subject to breakdowns.

Main functions.

The underfloor heating thermostat with a weekly program is controlled by a single-chip microcontroller.
High reliability. Saves energy and creates comfortable indoor conditions.
The device works with electric or water heating systems, starting electronic heating or activating the heating system. According to the set temperature, the thermostat automatically turns on and off the controlled object (valve, floor heater, wall heater, electric heaters, etc.).
Several time modes of operation: 5+2, 6+1, 7 days, allows you to set different temperatures for weekends and/or weekdays according to six time phases. In this operating mode, the user does not need to manually change the temperature depending on the phase of the day. This will happen automatically.
The stylish design of the thermostat will allow you to easily fit it into the design of the room. The smooth surface of the case will make the device easier to clean.
All settings are saved after the power is turned off, thanks to the built-in battery.
Keypad lock prevents children from accidentally changing device settings.

User manual

Turning on and off

By pressing a button you can turn the thermostat on or off.
The display looks like this when the thermostat is turned off.

Children Lock
Press the buttons and hold for about two seconds, after which the buttons will be locked. The lock icon will light up on the screen.
The lock is removed in the same way as it was placed, hold down the buttons for two seconds.

System time
To set the system time: Press and hold the button for 5 seconds to enter the time setting mode. Press and select the parameter you want to change (day of week / hours / minutes), press or to set the desired value of the selected parameter. To return to the previous time setting, press the button.
After setting the required minutes, press to exit the time setting mode.

Temperature Control Modes

The thermostat can operate in three different temperature control modes, enter advanced settings to set.
Built-in sensor(IN): Uses an internal sensor to measure temperature. This mode is suitable for controlling room temperature.
External sensor (OUT): An external sensor is used to measure temperature. This mode is suitable for controlling the floor temperature.
Both sensors (ALL): The thermostat uses both sensors to control temperature. This mode is suitable if you need to control the temperature in the room without overheating the floor

Temperature display in three modes

When the thermostat is in IN mode and ALL mode. The display shows the current air temperature in the room, as indicated by the active AIR icon.
When the thermostat is in OUT mode, FLOOR is lit. The display shows the current floor temperature measured by an external sensor.
When the thermostat is in ALL mode, press and to display the floor temperature or external sensor location and FLOOR will light up. After 5 seconds, the thermostat will automatically switch to the internal sensor readings and the word AIR will appear.

Automatic / manual mode

By pressing the button you can select the thermostat operating mode, automatic or manual.
Manual Mode: The thermostat automatically controls the manually set temperature until it is changed. The set temperature value is displayed below the current temperature reading and can be changed at any time using the and buttons accordingly.
Auto mode: The thermostat automatically controls the temperature at the level set by the program for the current time stage; when the time comes for the next stage, the system will maintain the temperature specified for it. When the thermostat operates in automatic mode, the indicator lights up. Inscriptions Week And Stage light up on the screen alternately with an interval of 5 seconds. When on screen WEEK, the number below indicates the number of the day of the week from 1 to 7. When on the screen Stage, the number below indicates the number of the active time step, from 1 to 6. Under the current temperature, the current time and the temperature set for the active time step are alternately displayed at 5-second intervals.

Setting time steps (thermostat programming)
Stage settings allow you to control the temperature over time automatically. Once you have configured the parameters, you will not need to do anything else; the thermostat will follow the program day after day, creating comfortable conditions for you. The thermostat automatically saves any changes you make and maintains them even after a power outage using a built-in battery.
The thermostat can operate according to three types of schedules (5+2 / 6+1 / 7) with 6 stages. With a cycle of one week.
The beginning of each stage is the time (hours, minutes) and the temperature value that are stored in the program. The end of the current stage is the beginning of the next one.
Press and hold for 5 seconds, you will enter the time stage setting interface. Numbers flashing below the inscription Week indicate which type of schedule is selected (5+2 or 6+1 or 7, by default the 5+2 mode is selected, so the numbers from 1 to 5 are blinking). To select the parameter (Stage start time: hours, minutes and temperature for this stage) that you want to change, use the button. Use or to change the value of the selected option.
Example: a schedule of type 5+2 (5 working days + two days off) is selected. The procedure for setting the period is:
Press and hold for 5 seconds, under the inscription Week, numbers from 1 to 5 will flash as in the figure on the right, set the parameters of the stages for working days P1: set hours>minutes>temperature-> P2: set hours>minutes>temperature -> P3: set hours>minutes>temperature ->...- > P6: set hours>minutes>temperature. Under the inscription Week The numbers 6 and 7 will flash.
let's set the parameters of the stages for weekends P1: set hours>minutes>temperature -> P2: set hours>minutes>temperature -> P3: set hours>minutes>temperature ->...-> P6: set hours>minutes>temperature. After setup last stage The thermostat will switch to automatic mode and begin executing the set program. Moving through the settings of time stages is carried out using the and forward and backward buttons, respectively. Setting the parameter value using the or button.
By default, the manufacturer has entered the following values for time stages:
