WARRANTY CARD
TECH company ensures to the Buyer proper operation of the device for the period of 24 months from the date of sale. The Guarantor
undertakes to repair the device free of charge if the defects occurred through the manufacturer’s fault. The device should be delivered to its manufacturer.
Principles of conduct in the case of a complaint are determined by the Act on speci c terms and conditions of consumer sale and amendments of the
Civil Code (Journal of Laws of 5 September 2002).
CAUTION! THE TEMPERATURE SENSOR CANNOT BE IMMERSED IN ANY LIQUID (OIL ETC). THIS MAY RESULT IN DAMAGING THE CONTROLLER AND LOSS
OF WARRANTY! THE ACCEPTABLE RELATIVE HUMIDITY OF THE CONTROLLER’S ENVIRONMENT IS 5÷85% REL.H. WITHOUT THE STEAM CONDENSATION
EFFECT.
THE DEVICE IS NOT INTENDED TO BE OPERATED BY CHILDREN.
Activities related to setting and regulation of the controller parameters described in the Instruction Manual and parts wearing out during normal
operation, such as fuses, are not covered by warranty repairs. The warranty does not cover damages arising as a result of improper operation or through
the user’s fault, mechanical damage or damage created as a result of  re,  ood, atmospheric discharges, overvoltage or short-circuit. The interference
of an unauthorized service, wilful repairs, modi cations and construction changes cause the loss of Warranty. TECH controllers have protective seals.

Controller advantages
• built-in temperature and humidity sensor
• wall-mountable housing
• front panel made of glass
Current temperature is displayed on the screen. Use the Menu button
(in the middle) to display current humidity. Press and hold the Menu
button to enter the menu.
DESCRIPTION
The EU-T-2.1 room regulator is intended for controlling the heating
device. Its main task is to maintain the pre-set room temperature by
sending a signal to the heating device when the room temperature has
been reached.
There are 2 color versions: white or black.

HOW TO INSTALL THE
REGULATOR
The regulator should be installed by a qualied person.
WARNING
• Risk of fatal electric shock from touching live connections.
Before working on the controller switch o the power supply
and prevent it from being accidentally switched on.
• Incorrect connection of wires may damage the regulator!
The diagrams below illustrate how the regulator should be mounted.
How to install particular elements:
HOW TO CHANGE THE PRE-SET

by means of buttons < >.
During inactivity, the screen displays current room temperature. Press <
or > to display the pre-set temperature value - the digits start ashing.
Use the buttons < > to adjust the value.
MENU FUNCTIONS
Press and hold the Menu button to enter the regulator menu. Use the
buttons < > to navigate through menu functions.

button. The screen displays the battery level.
3. Hysteresis
The His function enables the user to set the room temperature
hysteresis within the range of 0,2°C to 4°C. Room temperature
hysteresis denes the pre-set temperature tolerance in order to
prevent undesired oscillation in case of small temperature uctuation.
Example:
Pre-set temperature : 23°C
Hysteresis: 1°C
The room regulator reports that the temperature is too low when the
room temperature drops to 22 °C.
In order to dene the pre-set temperature hysteresis, use the buttons <
> and select a desired value. In order to conrm changes, wait for about
5 seconds or press the Menu button.
4. Calibration
The Cal function enables the user to calibrate the sensor within
the range of -10°C to +10°C. Select Cal and when the screen
