Description
How to use the regulator
The EU-R-8b Plus room regulator is designed to cooperate with TECH
external controllers.
It should be installed in heating zones. The regulator sends current room
temperature and humidity readings to the external controller, which
uses the data to control thermostatic valves (opening them when the
temperature is too low and closing them when the room temperature
has been reached).

How to register a room regulator in
a given zone
- Once registered, the sensor cannot be unregistered, but only disabled
by selecting OFF in the submenu of a given zone in the external controller.
Each room regulator should be registered in a zone. In order to register,
go to the external controller menu and select Sensor in the submenu of
a given zone (Zone / Registration / Sensor). After selecting Registration
icon, press the button on the back of the room regulator.
- If the user attempts to assign a sensor to the zone to which other
sensor has already been assigned, the first sensor becomes unregistered
and it is replaced by the other one.
- If the user attempts to assign a sensor which has already been assigned
to a different zone, the sensor is unregistered from the first zone and
registered in the new one.
If the registration process has been completed successfully, the external
controller screen will display a message to confirm whereas the room
sensor screen will display Scs. If the room sensor displays Err, an error
has occurred during the registration process.
It is possible to set individual pre-set temperature value and weekly
schedule for each room regulator assigned to a given zone. The settings
may be configured both in the external controller menu (Main menu/
temperature may also be adjusted directly from the room sensor using
the buttons < >.
