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 particular elements:
HOW TO CHANGE THE PRE-SET
TEMPERATURE
The pre-set temperature may be adjusted in the EU-T-2.1 room regulator
by means of buttons < >.
During inactivity, the screen displays current room temperature. Press <
or > to display the pre-set temperature value - the digits start flashing.
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.
1. Operation mode
The Out function enables the user to choose one of the regulator
operation modes: heating (HEA) or cooling (Coo). Select Out and
when the screen starts flashing, press the Menu button. The screen
shows available operation modes (Coo, HEA). Use the buttons < >

or press the Menu button.
2.
Battery
The Bat function enables the user to check the battery level (%).
Select Bat and when the screen starts flashing, press the Menu
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 defines the pre-set temperature tolerance in order to
prevent undesired oscillation in case of small temperature fluctuation.
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 define the pre-set temperature hysteresis, use the buttons <
> and select a desired value. In order to confirm 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
starts flashing, press the Menu button. The screen displays
current calibration value. Use the buttons < > to adjust the value.
5. Auto-lock
The Loc function enables the user to activate the key lock.
Select Loc and when the screen starts flashing, press the
Menu button. Next, the regulator asks if you want to activate
the key lock (yes/no). Select the answer using one of the
buttons < >. Wait 5 seconds to confirm. When the lock is active,
the keys are locked after a few seconds of inactivity. To unlock,
press and hold both buttons < >. If the screen displays Ulc, it
means that the keys have been unlocked.
6. Min/Max pre-set temperature
The Def function enables the user to restore factory
settings. Select this function and when the screen starts
flashing, press the Menu button. Next, the regulator asks
