After clicking on this icon you can change additional parameters.
Temperature Sensor
After clicking on this icon, you can see the panel which
allows the user to change the hysteresis settings and
calibration of the temperature sensor of the room regulator.
 Hysteresis
Hysteresis introduces tolerance for the set temperature
preventing
unwanted oscillations under minimal
temperature fluctuations (0 ÷ 10
⁰
C) with accuracy to 0.1°C.
Example: when the set temperature constitutes 23oC and
hysteresis is set to 1
⁰
C, the room regulator will begin to
indicate under heating in the room after the temperature
falls to 22
⁰
C
 Calibration
Calibration of the device is set during the installation. It can additionally be set after a longer period of
use of the regulator - if the room temperature measured by the internal sensor differs from the current
temperature. The regulation range is as follows: -10 to + 10
⁰
C with accuracy to 0,1
⁰

Main Controller Type
After clicking on this icon, the user selects the main controller type with which room regulator will
cooperate: standard, pellet or installation. After the selection is made, the Boiler control submenu will
be changed.
Software update
Insert the memory stick with the new software version in the USB port and click on the icon. The up-
date will happen automatically.
VI. Alarms
The EU-281 room temperature regulator will signal all
alarms generated by the main controller. When the alarm
activates, the room regulator will send sound signals and
the display will show the same message as the boiler
controller. In the case of internal sensor damage "room
temperature sensor fault" will appear.
