7. If wireless thermostatic actuators are used, they need to be registered in the
zones.
VI. How to use the controller
V.a) Principle of operation
L-6 controls the CH pump switching it on when the temperature in any of the six zones
or the built-in valve is too low. The controller receives temperature information from the
subordinate room regulators assigned to particular zones. If the temperature in any of
the zones is too low, the controller opens the valves in this particular zone.
L-6 receives temperature information from different zones via room regulators e.g. ST292v4, ST-290v4 or ST-286. Room regulators use wireless communication to send
information to the L-6 controller.
It is possible to connect a master room regulator (ST-285) which controls the operation
of the room regulators in all zones via wireless communication.
To each zone the user may assign wired valve actuators and the maximum of 9 wireless
actuators communicating with L-6 via radio signal (registration is required).

V.c.3) Channel
This function is used to select the channel for wireless
communication with the room regulators and the external
sensor. The user needs to select the same channel in all
devices communicating with the L-6 controller. The range
of channels is 0-20.
‘0’ is the default channel in the devices cooperating
with L-6. The channel must be changed only if there
is a conflict with other devices using radio
communication. In such a case the user must
remember to change the channel in all the devices
communicating with L-6.
V.c.4) Main valve
L-6 controller is equipped with a built-in module
controlling the mixing valve. There is a range of
parameters regulating the valve operation and allowing
the user to customize it to individual needs.
Valve status
In order to activate the valve select ON.
Pre-set valve temperature
This function is used to define the pre-set temperature of
the valve. It is measured by the valve sensor.
Opening time
This parameter defines the time needed for the valve to
open from 0% to 100%. The value should be adjusted to
the valve actuator used (information on the rating plate).
Valve type
This function is used to select the type of valve to be
controlled:
CH VALVE – this option is selected when the user
wants to control the CH circuit temperature
FLOOR VALVE - this option is selected when the
user wants to control the temperature in the
underfloor heating circuit. This function protects
the underfloor heating system against hazardous temperature. If CH valve type is
TECH
12
selected when the valve is connected to the underfloor heating system, the fragile
installation may be damaged.
Weather-based control
For the function of weather control to be active, the
external sensor mustn't be exposed to sunlight or
influenced by the weather conditions. After it is installed
in an appropriate place and wired up, weather control
function needs to be activated in the controller menu.
For the valve to operate correctly, the user defines the
pre-set temperature (behind the valve) for 4 intermediate
external temperatures:
-20ºC, -10ºC, 0ºC and 10ºC.
The user selects external temperature value using LEFT
and RIGHT arrows and defines a corresponding pre-set
temperature value using DOWN and UP arrows.
Subsequently, the display shows the heating curve.
Heating curve – it is a curve according to which the pre-
set controller temperature is determined, on the basis of
external temperature. In our controller, this curve is
constructed on the basis of four pre-set temperatures for
respective values of external temperatures.
The more points constructing the curve, the greater its
accuracy, which allows its flexible shaping. In our opinion,
four points seem a very good compromise ensuring decent
accuracy and easiness of setting the course of this curve.
NOTE
After weather-based control is switched on, pre-set valve temperature parameter is
not available. (Main menu-valve settings)
Factory settings
This function enables the user to restore the factory
settings for a particular valve. Restoring factory settings
does not change the selected valve type (CH or floor).
V.c.5) External sensor
The controller may be connected to a standard or wireless
external temperature sensor which enables weatherbased control of the built-in valve. Current external
temperature is displayed on the main screen. After the
external sensor is installed, the user needs to
define its type: standard or wireless.
!

WARNING
If a wireless external sensor is used, the user needs to check if the same communication
channel is selected in L-6 controller. ‘0’ is the default channel in the external sensor.
Channel change in the external sensor:
Press and hold the channel change button in order to change the communication channel.
When the control light flashes twice, the process of channel change has been initiated.
Hold the button and wait until the light starts flashing again. The number of flashes
corresponds to the channel number (1 flash – channel 1; 5 flashes – channel 5). After
the desired channel has been selected, release the button. In order to return to channel
0, repeat the procedure releasing the button after the first two flashes.
V.c.6) Pump
L-6 controls the pump operation switching it on when
necessary.
The pump is activated when the temperature in any of the
zones is too low or if the pre-set temperature of the builtin valve has not been reached (the built-in valve needs to
be active). If all room regulators report sufficient
temperature and the pre-set temperature of the built-in
valve has been reached (if the valve is active), the
controller switches off the pump.
Delay function allows the user to define the
time of pump activation delay after the
temperature in any of the zones is too low or
after the valve temperature drops below the
pre-set value.

V.c.11) Fitter’s menu
Fitter’s menu should be accessed by a qualified person.
It is intended mostly for adjusting additional functions of
the controller.
1) Registration
Wireless thermostatic actuators must be registered in
particular zones. The user may choose from 6 zones
(Valve 1-6). The maximum of 9 actuators may be
registered in one zone.
Registration procedure:
1. Install the thermostatic actuator on the radiator.
2. Go to Registration in the Fitter’s menu of L-6
controller.
3. Choose the zone number in which the actuator
will be registered and select Registration.
4. Press registration button on the controller. It
must be done within 30 seconds from selecting
Registration option in the menu – after this time
the registration process is considered unsuccessful.
5. If the registration process has been successfully completed,
the display shows the message confirming the registration
as well as the number of registered valves. If an error
occurs during the registration process, the display shows an
appropriate message. There are three possible causes of
errors:
o an attempt to register more than 9 actuators
o an attempt to register an actuator which has
already been registered
o no signal from the valve actuator within 30
seconds
2) Room regulator
L-6 controller may cooperate with a master room regulator
(ST-285) which enables the user to:
view the status of particular valves
change the pre-set temperature of a given zone – in
the case of using subordinate room regulators with
RS communication (ST-286)

view the status of an additional contact (ON/OFF)
Regulator TECH option needs to be selected in order for
the communication between L-6 and the room regulator
to be active.
3) Internet module
L-6 controller may cooperate with the Internet module
allowing the user to view and change some of the
parameters via the Internet. This type of control is
available only after purchasing and connecting an
additional controlling module ST-500 which is not included
in the standard controller set.
The Internet module may be connected to L-6 controller
with RS cable. Wireless communication is possible if an
additional module - ST-260 is used.
Internet module is a device enabling the user remote
control of the CH boiler via the Internet or local network.
The user controls the status of all valves on the home
computer screen.
If two-state room regulators are used, the user may check
if the temperature is sufficient/insufficient. Room
regulators with RS communication enable the user to view
the current room temperature as well as change its preset value.
After switching the module on and selecting DHCP option,
the controller automatically downloads such parameters
as IP address, IP mask, gateway address and DNS
address from the local network. If any problems arise
when downloading the network parameters, they may be
set manually. The procedure of obtaining these parameters is described in detail in the
instruction manual of the Internet module.
Module password reset function may be used when the user has changed the default
password on the login page. If the user's new password is lost, the default password may
be restored by resetting the module password.
4) Clock
This function is used to set current time and day of the
week.
TECH

VII. Protections and alarms
In order to ensure safe and failure-free operation, the regulator has been equipped with
a range of safeguards. In case of alarm, a sound signal is activated and the display shows
an appropriate message.
Automatic sensor control
If the valve temperature sensor or the external sensor is damaged, an alarm sound is
activated and the display message informs about the failure
e.g. 'Sensor damaged'. The pump is active regardless of the current
temperature.
The alarm is active until a new sensor is installed.
Fuse
The regulator has a WT 6,3A tube fuse-link (5x20mm) protecting the network.
CAUTION: Higher amperage fuse should not be used as it may damage the controller.
