Technical Information
This product complies with the essential requirements and other relevant provisions of the following
EU Directives: EMC 2014/30/EU, Low Voltage Directive LVD 2014/35/EU, RoHS directive 2011/65/EU.
The heating circuit module makes it possible to operate two independent heat zones to which
temperature controllers and circulation pumps are connected. It is used in typical single-family
housing, where there are divisions into 2 heating circuits (e.g. 1 rst oor circuit and 2 oor circuit).
Then the signal coming from any of the heating circuits activates the outputs to the main circulation
pump and the heat source in the controller.The integrator can also be used for small (e.g. two-zone)
oor heating systems.
Use in accordance with national and EU regulations. Device is intended for indoor use only
in dry conditions. Product for indoor use only. Installation must be carried out by a qualied
person in accordance to national and EU regulations.
Before attempting to setup and install, make sure that
ECB02M230
is not connected to any
power source. Installation must be carried out by a qualied person. Incorrect installation
may cause damage to the wiring centre. The
ECB02M230
should not be installed in areas
where it may be exposed to water or damp conditions.
PLEASE NOTE:
For the entire installation, there may be additional protection requirements, which the
installer is responsible for maintaining.

The MAIN PUMP and BOILER outputs are used to control the main circulating pump and
the heat source in the heating system.The outputs are turned on when a heating signal
is received from any room controller connected to the integrator.The outputs are turned
o when none of the controllers sends a signal for heating.

If the temperature is exceeded,
the thermal protection will turn o the
circulation pump in the circuit in question
If the integrator was used for underoor heating, additional thermal protection can be used
(e.g., a bimetallic touch thermostat).

Power supply
Power supply for wiring centre is 230V ~ 50Hz.
Installation features:
• three-wire,
• made in accordance with applicable regulations.
The red LED
indicates that the wiring centre is connected to the power supply.
Fuse
Please note: Replacement of the fuse to be carried out only when the control
box is disconnected from power supply (230V ~)..
Main fuse is located under the housing cover next to power supply terminals and
secures the control box and the devices connected to it. Use ceramic tube slow blow
250 V ROHS fuses (5x20 mm) with nominal max current 6,3A. To replace fuse remove
the fuse holder with a at screwdriver and pull out the fuse.
