1SAFETY INFORMATION
Requirements concerning safety are listed in
particular sections of this instruction. Apart
from them it in necessary to fulfill the following
requirements.
Controller can be assembled only by
qualified installer and in accordance with
currently valid standards and
regulations.
Prior to starting the assembly, repairs or
maintenance and during the execution
of any connection works, it is necessary
to switch off the mains supply and make
sure that no terminals no electrical
wires are energized.
After deactivating the controller with the
use of a keyboard, terminals of the
controller can be under a dangerous
level of voltage.
The controller can be utilized only in
accordance with its intended use.
Additional automatics should be used in
order to protect central heating and
HUW system against the results of
regulator failure or software errors.
Particularly control automatics which
reduce HUW temperature in order to
protect users against burns.
The controller cannot be used as the
only protection against frozen central
heating system.
Values of programmed parameters must
be set in accordance with a particular
building and hydraulic system.
The controller is not an intrinsically safe
device. It means that in case of failure it
can be a source of sparks or high
temperature which surrounded by ashes
or flammable gases can cause fire or
explosion.
Modification of the programmed
parameters should be made only by a
person who read this manual.
Use only in heat circulation system
made in accordance with currently valid
regulations.
Electrical system including the controller
should be 3-wired and protected with
fuse selected in accordance with used
loads.
The controller cannot be used with
damaged housing.
Never make any modifications in
controller structure.
The controller consists of two
components: control panel and output
module. Replaced component must be
compatible.
The controller is equipped with a
protection against Legionella bacteria.
The controller periodically heats the
HUW tank up to a temperature which
can cause scalding to operator. Installer
should provide information whether the
function is active and additional
automatics protecting against scalding is
installed.
Keep children away from the controller.

2Controller intended use
The controller is intended for controlling:
-central heating system,
-HUW tank,
-HUW circulation system,
-solar circulation system.
The controller can be connected to the
automatic boiler equipped with activating or
deactivating contact (ON/OFF switch).
The controller can control the pump and valve
switching additional heat sources, e.g. boiler
with water jacket.
Using the controller for other purposes than its
intended use is forbidden. Manufacturer does
not bear any responsibility for any loss caused
by such use.
3Information concerning
documentation
This instruction applies only to controllers with
software and hardware versions listed on the
first page. Program version can be verified in:
menu →information.
Manufacturer nor supplier of the controller
does not bear any responsibility for damages
due to non-compliance with this manual.
4Documentation storage
Please keep this operation and assembly
manual and other valid documentation in a
safe place for future reference. In case of
moving or selling the device, hand this
documentation over to a new user or owner.
5Used symbols
The following graphical symbols are used in the
manual:
- useful information and tips,
- useful information concerning property
damage, health or life threat for people
or pets.
Caution: important information were labeled
with the aforementioned symbols in order
make the manual easier to understand.
However it does not release the user nor
installer from responsibility of complying with
requirements which are not labeled with any
symbols!

CONTROLLER OPERATION MANUAL

FOR THE USER

7Controller description
7.1 Controller structure
The controller consists of a touch control
panel (1) and control module (3). Both
components are connected with a 4-signal
cable (2). An external temperature sensor
(4) connected with the module (3) with 2-
wire cable (5) is necessary for proper
operation of the system. Touch control panel
(1) can be placed in a house apartment, e.g.
in the living room or hall. Module (3) should
be placed in the boiler room close to
electrical devices included in the central
heating system. Cable (2) should meet the
requirements listed in installer’s manual.
Control panel is equipped with a room
temperature sensor and therefore it also acts
as a room thermostat. There is a possibility
of connecting many control panels measuring
room temperature for various heat
circulations.
7.2 Controller operation
Heat source
The controller controls the operation of heat
source, e.g. an automatic gas, oil or pellet
boiler, by activating or deactivating it
according to a heat demand of the central
heating system.
Hot utility water
The controller controls the operation of HUW
pump loading a hot water tank up to a user-
defined temperature. Preparation of HUW
can be programmed in time intervals. The
controller also controls a HUW circulating
pump. It enables quick transportation of
HUW to a bathroom or kitchen located far
away.
Heating circuits
The controller control the operation of one
direct heating circuit (radiator) and two
adjustable heating circuits (radiator or floor).
Water temperature in heating circuits is set
by weather, i.e. water temperature in the
heating circuit is calculated in accordance
with a temperature from the external sensor.
Due to this, despite of varying external
temperature, a room temperature in heated
compartments are kept on a set level.
Dependent and independent heating
circuits
- Dependent heating circuits –controller
touch panel can be a common room
thermostat for many heating circuits. For
example, room temperature readings on a
panel installed in the living room affect
operation of both radiator and floor circuit.
Both these circuits heat up a common
temperature sensor located on the screen by
supplying heat.
- Independent heating circuit –there is a
possibility of connecting many control panels
measuring room temperature independently
and affecting assigned heating circuits. It is
the way to obtain independency of heating
circuits, e.g. in case when one part of the
building is used for the whole year and the
second part is used periodically, e.g. for rent.
More details are include in pt.10.10.
Solar system
The controller controls a basic solar system
heating the HUW tank. Apart from
temperature sensors, no additional module is
necessary to operate the solar system.
