- Power Supply: 230 V AC 50 Hz 6(1)A
- Dimensions: 150 x 90 x 35 mm
Product Description
The ECB02M230 Control Box is designed for managing heating
circuits in a heating system. It features two circuits for
controlling the main pump and boiler, ensuring efficient heating
control.
Installation
- Ensure the control box is disconnected from the power supply
before any installation or maintenance. - Connect the power supply (230 V AC) ensuring correct
polarity. - Connect the main pump and boiler outputs to their respective
devices following the provided instructions.
Operation
The control box activates the main pump and boiler outputs based
on signals received from room controllers. The green LED indicates
when the outputs are activated. Ensure proper functioning as per
the boiler’s manual.
Connection Contacts
The control box allows for various thermostat connections,
including battery thermostats, 230V thermostats, and wireless
thermostat receivers. Follow the provided circuit connection
contacts for each type of thermostat.
Fuse Replacement
Replace the fuse with a ceramic tube slow blow 250V ROHS fuse
(5×20 mm) only when the control box is disconnected from the power
supply. Locate the main fuse under the housing cover next to the
power supply terminals.
Safety Information
For additional protection requirements during installation, the
installer must ensure compliance with safety standards and
regulations.
Power Supply
The red LED indicates a successful connection to the power
supply. Verify proper installation and connection for safe
operation.
FAQ
Q: What should I do if the green LED does not light up?
A: Check the connections of the main pump and boiler outputs.
Ensure the signals from room controllers are reaching the control
box.
Q: Can I use this control box for underfloor heating
systems?
A: Yes, additional thermal protection can be used for underfloor
heating. Follow the instructions provided for proper
integration.

Introduction
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 first floor circuit and 2 floor 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) floor heating systems.
Product compliance
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.
Safety information
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 qualified 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 qualified 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.

Fuse
Please note: Replacement of the fuse to be carried out only when the control box is disconnected from power supply (230 V ~).. 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 (5×20 mm) with nominal max current 6,3A. To replace fuse remove the fuse holder with a flat screwdriver and pull out the fuse.

Boiler and main pump outputs
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 off when none of the controllers sends a signal for heating.

If the integrator was used for underfloor heating, additional thermal protection can be used (e.g., a bimetallic touch thermostat).
If the temperature is exceeded, the thermal protection will turn off the circulation pump in the circuit in question
If thermal protection is not used, a short circuit should be used in its place
