7 Controller description
Controller structure
The controller (1) has a single module
construction, which includes a control panel
and an main module. To operate the system,
an external temperature sensor (3) connected
to the controller module via a cable (2) is
necessary. The controller should be placed in
the boiler room close to electrical devices
included in the central heating system.
Controller operation
Heat source
The controller controls the operation of heat
source, equipped with an ON-OFF contact,
e.g. an automatic gas, oil or pellet boiler, by
activating or deactivating it according to a
heat demand of the central heating system. It
has a 0-10V control output, which is used to
modulate the heat source's power depending
on the heating system's heat demand.
Hot domestic water
The controller controls the operation of DHW
pump loading a hot water tank up to a userdefined temperature. Preparation of DHW can
be programmed in time intervals. The
controller also controls a DHW circulating
pump. It enables quick transportation of DHW
to a bathroom or kitchen located far away.
Heating circuits
The controller control the operation of one
direct heating circuit and two adjustable
heating circuits. 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 heating circuits
The temperature in individual heating circuits
can be asked in several ways:
- weather control – with consideration to
external temperature sensor readings,
- constant value – without external
temperature sensor,
- with using modes of work with time
schedules, without using additional room
thermostats,
- with using room thermostats or other
heating systems, which by means of contacts
(closed) affect individual heating circuits.
Solar system
The controller controls a basic solar system
heating the DHW tank. Apart from
temperature sensors, no additional module is
necessary to operate the solar system.

Environmental conditions
Due to fire risk it is forbidden to use the
controller in proximity of explosive gases or
dust. Moreover the controller cannot be used
in conditions of water steam condensation or
be exposed to effects of water.
Storage and transport
conditions
The controller cannot be exposed to
immediate effects of atmospheric conditions
i.e. rain or sunrays. Temperature of storage
and transport should be within scope
-15…+65°C.
Mounting requirements
Regulator should be installed by qualified and
authorized technician with observance of
applicable standards and regulations.
The manufacturer disclaims any liability for
damage caused by non-observance of
instructions specified in this manual.
Ambient temperature and temperature of
mounting base should be within the range of
0…50˚C.
Prior to installing the controller make sure that
it will properly cooperate with hydraulic and
electrical system.
Module installation
The regulator should be screwed on to the flat
horizontal or vertical surface (e.g. boiler
housing, room wall). To screw on the
regulator use mounting holes and proper
screws. Location and spacing of mounting
holes are shown in the picture below.
The regulator must not be used
as a free-standing device.
After installation make sure that the device is
properly mounted and it is impossible to
detach it from the mounting surface.
The regulator casing provides the IP20
protection rating. The casing on the
connectors cover side provides IP00 rating,
and because of that connectors must be
unconditionally covered with the cover.
If there is a need to gain an access to the
terminals side, it is a must to disconnect the
mains voltage and make sure there is no
dangerous voltage on regulator terminals.
Temperature sensors assembly
The controller cooperates solely with
temperature sensor type CT-10, CT6-P, CT6W. The use of other sensors is prohibited.
At least one heating circuit temperature
sensor and one external temperature sensor
(weather sensor) are necessary to activate
the controller.
Caution: the controller is equipped
with various types of temperature
sensors! Connecting an
inappropriate sensor will cause
incorrect operation of the controller!
Sensors for heating circuits
Direct heating circuit sensor should be
installed in a hydraulic coupling. If there is no
hydraulic coupling in the system, it can be
fixed to a supplying pipe coming out of the
heat source (from boiler).
Assemble the adjustable heating circuit
sensor on a pipe after the heating circuit
pump. Insulate sensors affixed to the
external surface of the pipe with the use of
thermal insulation covering the sensor
together with the pipe.
Mounting temperature sensor: 1 - pipe, 2 – clamps, 3 thermal insulation, 4 - temperature sensor.
Page 15

External temperature sensors
The controller cooperates only with a CT6-P
type weather sensor.
Sensor should be fixed to a coldest wall in the
building. Usually it is a north wall under the
roof. Sensor should not be subjected to direct
solar radiation nor rain. Sensor should be
fixed on a minimum height of 2m above the
ground and in a distance from windows,
chimneys and other heat sources which could
interrupt the temperature measurement (at
least 1,5m). Use a connecting cable with a
cross section of at least 0,5mm2 and length of
25m. Polarity of wires is not important. Fix the
sensor to the wall with the use of screws.
Holes containing fixing screws can be
accessed by unscrewing a sensor cover.
Connecting the CT6-P external temperature sensor.
Temperature sensors checking
Temperature sensors can be checked by
measuring their resistance in given
temperature. In case of big differences
between measured resistance value and
values in table below, the sensor should be
replaced with a new one.

Preparation of DHW can be optimized by
appropriate programming of time program for
DHW tank. Set DHW tank work mode to Auto.
Define time program for DHW tank in such
way to set insolation periods as “NIGHT”. Due
Page 17

to this the boiler will not heat up the DHW
tank. Similar effect can be obtained by setting
the work mode for DHW tank to Off manually.
Loading DHW tank can be also optimized by
setting a lowest possible preset temperature
of DHW tank. The lower preset temperature of
HUW tank, the less often boiler will become
active in order to load the tank and solar
energy gain will be higher.
Installer from a service level should set the
highest possible DHW tank maximum
temperature. This will generate the maximum
heat gain. On the other hand there is a risk of
scalding with hot water and exceeding
temperature limit for a particular DHW tank!
Risk of scalding with DHW!
In order to protect against
scalding, install an additional
protective automatics, e.g.
thermostatic mixing valve.
During periods of very high insolation, there
can be a situation in which the HUW tank is
not able to absorb big amount of heat. In such
case, a solar pump transporting heat from a
solar panel to HUW tank becomes off. Due to
a risk of damaging the pump, it is turned off
only when the solar panel temperature drops.
In practice, the solar system is turned on
again the next day after the sunrise. It
indicates a normal operation resulting from
the fact that there is no possibility of
absorbing the heat surplus.
Weather control
In order for the room temperature to be
stable, must be set the weather control. The
weather control must be activated separately
for each heating circuit. The weather control
is influenced by the setting of the heating
curve and the curve parallel shift.
The heating circuit water preset temperature
is calculated basing on the temperature
prevailing outside the building. The colder it is
outside, the higher water temperature in the
heating circuit is. This relation is shown in the
controller in the form of heating curve.
The heating curve can be changed in a graph
from the system menu, within the range for
the weather preset temperature. It is a
reflection of the thermal characteristics of the
building. If the building is less insulated then
the heating curve should be greater.
Setting the heating curve: Tp – temperature preset by
weather, Tz – exterlan temperature.
Heating curve should be selected
experimentally by changing it in a few day
intervals.
During trial and error selection of
appropriate heating curve, it is
necessary to exclude influence of
the thermostat on regulator
operation (regardless of whether
the thermostat is connected or
not), by setting the parameter
Thermostat = OFF for each heating
circuit.
After choosing the proper heating curve, the
circuit preset temperature is calculated
according to the outside temperature. As a
result if the heating curve is appropriate for
the building, the room temperature remains
constant regardless of the temperature
outside.
Guidelines for selecting a proper heating
curve:
- if at dropping external temperature, room
temperature increases, the selected heating
curve is too high,
- if at dropping external temperature, room
temperature also drops, the selected heating
curve is too low,
Poorly warmed buildings require setting
higher heating curves. Whereas for well
heating buildings, heating curve will have a
smaller value.
The range of the heating curve is limited by
the minimum and maximum preset water
temperature.
Thermostat settings
In order for the room temperature to be
stable, the thermostat should be activated.
The thermostat complements the weather
Page 18
18
control and corrects the water temperature in
the heating circuit if the room temperature is
still inadequate.
A thermostat must be activated for each
heating circuit. To do this, set the Thermostat
= ON.

12 Electrical system
The controller is designed to be supplied with 230V~, 50Hz voltage.
System features:
• three-wire (with protective wire PE),
• made in acc. with currently valid regulations.
Caution: Risk of electric shock caused by current from a heat source. Disconnect the
controller and heat source electrical supply and make sure there is no dangerous voltage
on terminals. Protect yourself against incidental generation of supply voltage!
Connection cables should not be in contact with surfaces of temperature exceeding their nominal
work temperature. Terminals 1-25 are purposed for connecting devices with mains supply of
230V~. Terminals 26–55 are purposed for cooperation with low-voltage devices (under 12V).
Connecting mains supply 230V~ to terminals 26-55 will damage the controller and may
cause electric shock!
Tips of the connected wires, especially power leads, must be secured against splitting by means of
insulated clamps. The terminals of the protective strip must be tightened even if there is no wire
connected to the terminal.
Securing wire tips: a) – right, b) – wrong, c) - the requirement to tighten the screws of the protection strip, where: 1 –
connector, 2 – protection strip.
Should be tighten all screws of the protective strip clamp and make sure that no wire
core strand inserted into the terminals has an electrical contact with a metal protective
strip.
All peripherals may be connected only by qualified person in accordance with applicable
regulations. Safety precautions to prevent electrocution shall be observed. Regulator
shall be equipped with a set of pins connected to 230V AC mains.
Metal mounting surface on which the controller is mounted and protection lead of the power supply
cable and protection leads of connected devices should be connected to the grounding strip placed
inside the casing of the regulator marked with .
Before making any connections remove the cover from the casing of the regulator as shown below.

Connecting wires to the controller terminals: 1 – connector, 2- protective strip, 3 - holdfasts placing (should be broken out
for the casing), 4 - cable outlets, 5 - improper cable connection, 6 - holdfast of the cable.
Electrical cables should be isolated from hot parts of the boiler, especially from flues.
When the cables connection is done the cover of the connectors has to be put in place.
The connectors cover should be always screwed on to the casing of the regulator. Apart
from providing safety for the user, the connectors cover also protects the interior of
the regulator from hazardous environmental conditions providing a proper level of the

Minimum preset temperature of water in the DHW tank.
DHW maximum
temperature
25…92
55°C
Maximum preset temperature of water in the tank. This parameter
determines the maximum temperature to which the DHW tank will
be heated while discharging exceeding boiler heat from a boiler
or solar collector. Setting too high value can lead to the risk of
scalding with DHW. Too low parameter value will eliminate a
possibility of discharging heat excess to the DHW tank when the
boiler is overheated. In installations including a solar system, too
low value will reduce heat contacts because the solar pump loads
the DHW tank to a DHW maximum temperature. DHW system
developer should consider a possibility of the controller failure.
Such failure can cause heating the water inside DHW tank up to
a hazardous temperature causing a risk of scalding for users.
Therefore, thermostatic valves should be used as an additional
protection.

If Minimum pump rotations > 0, solar pump revolutions modulation
function is enabled. Function enables to increase reception of
heat energy from the solar panel at low insolation. Solar pump
decreases its revolutions when difference between temperatures
between a solar collector sensor and DHW tank lower
temperature drops.
Frost protection
mode - solar
-15…-35
0°C
Solar panel temperature at which frost protection mode is
activated. This value should be higher than freezing temperature
of the agent inside a solar circuit, e.g. glycol. Solar pump is
activated when solar panel temperature drops below Frost
protection mode - solar parameter value. It causes heat reception
from DHW tank and heating the solar panel. Caution: enabling this
function can cause considerable heat energy losses. When Frost
protection mode – solar = OFF, frost protection mode of the solar
is disabled.
DHW maximum
temperature
25…90
55°C
Maximum preset temperature of water in the tank. This parameter
defines what temperature the DHW tank will be heated up to
during the solar collector is loaded. It is a very important
parameter because if it is too high, there could be a risk of burning
with utility water. In case of installations with solar system, too low
value will limit heat gains because solar pump loads the DHW tank
to DHW maximum temperature. During designing a DHW system,
a possibility of regulator fault should be taken into consideration.
As a result of such failure, water inside the DHW tank can be
heated up to a temperature which is dangerous for users.
Therefore, additional protection should be used in a form of
thermostatic valves.
Night cooling
The controller activates night cooling from 0:00 a.m. to 5:00 a.m.
During this time the regulator will start the collector pump in order
to discharge the DHW tank to the set temperature. Regardless of
the conditions, the controller will exit the cooling mode at 5:00 a.m.
and will go to normal control. Setting Night cooling = OFF disables
the function.
