Tech Controllers EU-R-10z User Manual page 2

Description
EU-R-10z room regulators are installed in heating zones. They send
temperature information to EU-L-10 external controller, which uses the
information to control the thermostatic actuators (opening them when
the room temperature is too low and closing them when the pre-set
temperature has been reached).
Current temperature is displayed on the screen.
Controller assets:
• built-in temperature sensor
• wall-mountable cover

1. Light intensity sensor
2. Display - current zone temperature.
3. Control light (The light is flashing - the pre-set zone temperature has not
been reached. The light is on - the pre-set temperature has been reached.)
4. PLUS button
5. MINUS button
The regulator also has a built-in light intensity sensor, which is responsible
for the brightness of the display. When it is dark in the room, the screen
dims and when it is light, the screen brightens.
Change of pre-set temperature
The pre-set zone temperature may be changed directly in EU-R-10z
controller using PLUS and MINUS buttons.
During controller inactivity, the displays shows current zone temperature.
Press PLUS or MINUS to adjust the pre-set temperature - the digits will
start flashing.
After setting the desired temperature value, wait 3 seconds to save the
settings.
Hysteresis
Room temperature hysteresis is used to define tolerance of the pre-set
temperature in order to prevent undesired oscillation in case of small
temperature fluctuation. For example:
Pre-set temperature is 23°C
Hysteresis is 1°C
Room regulator temperature is considered too low when it drops to 22°C.
In order to set the hysteresis, press plus and minus buttons (+ -) at the
same time. Set the desired value and wait 3 seconds to save the settings.
EU Declaration of conformity
Hereby, we declare under our sole responsibility that EU-R-10z
manufactured by TECH, headquartered in Wieprz Biała Droga 31, 34-122
