NOTE
The user should enable the Internet module to connect with data servers listening on TCP/2000 port. Most computer
networks are protected by various software (firewalls, anti-virus software etc.) which may block data exchange with
the above mentioned port. If any problems arise, contact technical support or your computer network administrator.
Step 4. Activate the external sensor
NOTE
Deactivating the sensor in the controller menu only interrupts communication (the external temperature is no longer
displayed on the controller screen) but it does not disable the external temperature sensor. The sensor remains
active until the battery gets empty.
Step 5. Set current time and date
Set current time and date in the fitter’s menu.
Step 6. Configure the settings for wireless thermostatic actuators STT-868 /STT-869
If you also use wireless actuators STT-868 or STT-869, it is necessary to register each actuator in a zone.
NOTE
The maximum of 6 actuators may be registered in each zone.
Registration process:
1.
Install the thermostatic actuator on the radiator and wait until it calibrates.
2.
Go to the controller menu, select the number of zone in which the actuator is to be registered and select
Registration/Register valve.
3.
Press the registration button on the actuator within 120 seconds from selecting Register valve option. After this
time EU L-8 considers the registration attempt as unsuccessful.
4.
If the registration process has been completed successfully, the display shows an appropriate message and
informs about the number of valves registered. In the case of any errors, the display shows appropriate
message. There are 3 possible causes of errors in the registration process:
-
An attempt to register more than 6 actuators.
-
An attempt to register the actuator which has already been assigned to a different zone
- No signal from the valve actuator within the period of 120 seconds.
Communication
button
The external sensor should be registered by selecting
Registration (in the controller’s menu) and pressing
communication button on the external sensor.
Completing the registration procedure activates the
sensor automatically. It may be switched off at any time
by selecting OFF option.
