Detailed description of the output S included in point 12.6.

17
Connecting electrical system
Regulator is designed to be fed with 230V~,
50Hz voltage. Supply is connected to
terminals L, N, PE.
The electrical system should be:
three core (with protective wire PE),
z in accordance with applicable
regulations.
Supply wires must be lead so as their contact
with sensor and other low-voltage cabling is
prevented, additionally, all cables may not
contact surfaces with temperatures that
exceed the cables operating temperature
limits.
The controller has no PE protective connector,
because the controller itself does not require
grounding. PE terminals of the pump, mixer
actuator shall be connected with PE of supply
network, according to periphery instructions
and regulation concerning electric systems.
Connecting mains supply 230V~
to terminals for sensors will
damage the regulator and creates
risk of an electric shock!.
Tips of the connected wires, especially power
leads, must be secured against splitting by
means of insulated clamps, in accordance with
the drawing below:
Securing wire tips: a) - right, b) - wrong.
Fixing the external wires
Electric cables external circuits are predicted
for the installation of surface-mounted. A
concealed external cable outlet should be
provided, as well as protection against the
wire being pulled out, loosened or strained,
using electric cable tray. It is not allowed to
leave any cable leads loose, to roll the excess
wire or to bend the wires into acute angles.
It is not allowed to roll the excess wire or to
leave disconnected cables inside the regulator
housing, as it may lead to damage to the
controller.
Example how to install the cables using
electric cable trays is shown in the figure
below.
Insulated clamp sleeve of 6 mm length

18
Connection of temperature sensors
Use only following sensor types: CT10, CT6-P.
The use of other sensors is prohibited.
Sensors cables could be extended by a cable
with cross-sectional area min. 0,5mm2, a total
cable length max. 15m.
Boiler temperature sensor should be installed
in thermostatic pipe installed in boiler. Mixer
temperature sensor should be installed in
sleeve located in stream of running water in
pipe, but also it can be installed on the pipe,
on condition that it is thermo isolated from the
environment.
Mounting temperature sensor: 1 - pipe, 2 –clamps,
3 - thermal insulation, 4 - temperature sensor.
Sensor must be protected from
getting loose from the surfaces to
which they are connected.
Good thermo contact should be maintained
between sensors and measured surface. To
this purpose thermoleading paste should be
used. It is not acceptable to lubricate sensors
with water or oil. Wires of sensors should be
separated from network electrical wires. In
such a case wrong readings of temperature
may be shown. Minimum length between
those wires should be 100mm. It is not
acceptable to allow for contact betweens wires
of the sensors and hot parts of the boiler and
heating installation. Wires of the sensors are
resistant to temperature not exceeding
100ºC.
From the regulator can also be formed to
correct an error reading from temperature
sensors: circuit heating, external, return and
boiler to the nearest 0,1°C.
The value correction set in:
Service settings →Temperature
correction
Connecting weather sensor
(external)
The regulator cooperates only with a weather
sensor of the CT6-P type. The sensor should
be installed on the coldest wall of the building,
usually this is the northern wall, under a roof.
The sensor should not be exposed to direct
sunlight and rain. The sensor should be fitted
at least 2m above the ground, far from
windows, chimneys and other heat sources
which could disturb the temperature
measurement (at least 1,5m).
Connect the sensor using cable of 0,5mm2
cross-section, up to 25m long. Polarity of the
leads is insignificant. Connect the other end of
the cable to the regulator.
Attach the sensor to the wall using tackbolts.
To access the tackbolts holes, unscrew the
sensor lid.

19
Temperature sensor checking
Temperature sensors CT10, CT6-P 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.

Connecting a room thermostat
Room thermostat (NO-NC) connected to the
control affects the heating circuit.
The thermostat after contact opening reduces
the preset temperature heating circuit about
the service value Decrease of thermostat or
can turn off the pump in the parameter Off by
thermostat. The values of the parameters
must be chosen so that when of working the
room thermostat (contact opening) the
temperature in the room dropped.
Connecting a heat source
COM-NO terminals are used to connect the
contact heat source (no voltage) that turns on
and off the heat source. The heat source can
be automatic boiler gas or oil, which has a
contact ON-OFF. Terminals COM-NO does not
have galvanic isolation of 230V ~ and can
therefore only serve to disconnect circuit
voltage of 230V ~. Use separate relay in the
event of having to disconnect circuits at low
voltage.
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 to heat source (gas or oil boiler)
should be done by a qualified installer,
according to technical data of this boiler.
