DESCRIPTION
The EU-F-8z room regulator is intended to be used with external
controllers. It should be installed in heating zones. The regulator sends
current temperature and humidity readings from a given zone to the
external controller. Based on the data, the external controller manages the
thermostatic valves (opening them when the temperature is too low and
closing them when the pre-set temperature has been reached).
Current temperature is displayed on the main screen. In order to display
current humidity value, press the Menu button (in the middle).
Controller equipment:
• built-in temperature sensor
• air humidity sensor
• intended to be mounted in a frame
• front panel made of glass
The regulator is intended to be mounted in a frame. It ts in the following
frames:
Ospel - Sonata
Berker - S.1, B.1, B.3, B.7
Jung - AS, A500, A PLUS, A CREATION
Gira- STANDARD 55, E2, EVENT, ESPRIT, PROFIL55, E22
Kopp - ALASKA
Elko - RS16, PLUS
HOW TO USE THE CONTROLLER
• REGULATOR DESCRIPTION
• DISPLAY DESCRIPTION
Current temperature is displayed on the screen. Use the Menu button (in
the middle) to display current humidity.
HOW TO INSTALL
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!

HOW TO REGISTER A REGULATOR
The room regulator must be registered in a zone.
In order to do it, go to the external controller menu and select Zones
and Registration. Next, in the menu of the room regulator select the rEg
function and press briey the registration button on the right side of the
regulator housing.
If the registration has been successful, the external controller display will
show a message to conrm and SCs will be displayed on the regulator
screen. Err displayed on the screen means that an error occurred during
the registration process.
NOTE
Only one room regulator may be assigned to each zone.
NOTE
In zone controllers, the room regulator may serve as a room
sensor or a oor sensor. In order to register the device as a oor
sensor, press the communication button on the regulator twice.
The following rules must be kept in mind:
- Once registered, the regulator cannot be unregistered, but only
disabled by selecting OFF in the submenu of a given zone in the external
controller.
- If the user attempts to assign a regulator to the zone to which another
regulator has already been assigned, the rst regulator becomes
unregistered and it is replaced by the other one.
- If the user attempts to assign a regulator which has already been
assigned to a dierent zone, the regulator is unregistered from the rst
zone and registered in the new one.
HOW TO CHANGE PRE-SET TEMPERATURE
The pre-set zone temperature may be adjusted directly from the EU-F-
8z room regulator using the buttons and .
During controller inactivity, the main screen displays current zone
temperature. After pressing one of the buttons or , the current
temperature is replaced with the pre-set temperature (the digits are
ashing). Using the buttons the user may adjust the pre-set
temperature value. About 3 seconds after setting the desired value, the
display will show a screen enabling the user to dene how long the new
setting should apply.
Time settings may be adjusted with the use of buttons:
- permanently – press until Con appears on the screen (the
pre-set value will apply all the time regardless of schedule settings);
- for a specied number of hours – press one of the buttons
- until the desired number of hours appears on the screen e.g. 01h (the
pre-set value will apply for the specied period of time; after that the
weekly schedule will apply);
- if the temperature value dened in the weekly schedule settings should
apply, press until the screen displays OFF.
When a sun icon appears next to the temperature value, it means that
the pre-set room temperature has been reached and heating has been
disabled. If the sun icon is ashing, the room is being heated and the
pre-set temperature hasn’t been reached yet.
