Introduction

ECB08M230 control box is the main element of the underfloor heating control system. It has a built-in modules that controls the heat sources (by volt-free relay) and pump (230V AC). The control box allows to control 8 different zones. It is equipped with 230V AC voltage outputs actuators. Pluggable terminal blocks provide quick and convenient wiring connections. The control box is designed to work with NC (normally-closed) type actuators.

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 ECB08M230 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 ECB08M230 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.

Technical Information

Terminals for actuators (230V AC)

Dimensions [mm]| 327 x 110 x 37

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.

Power supply

Power supply for wiring centre is 230 V ~ 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.

Boiler control output (volt free)

The boiler control output is supported by a relay with voltage-free contacts (NO / COM / NC output). The boiler must be connected to the COM-NO or COM-NC contacts. It is a typical two-state relay. In most cases, the NC terminal is not used. If the thermostats connected to the wiring centre send a signal for heating, the BOILER output contacts activate the relay with a 3-minute delay, allowing the boiler to be turned on. The boiler is turned off immediately, when none of the zones sends a signal for heating.

Thermostats input connections

• a – 230V thermostat connection (with COM / NO voltage-free contacts), e.g. E10W230WIFI / E10B230WIFI
• b – Connecting a battery ON / OFF thermostat (with voltage-free COM / NO contacts), e.g. E901
• c – 230V thermostat connection (with SL – 230V voltage output)

Actuators output connections (AC 230V)

Actuators wires should be plugged into the pluggable terminal blocks of the respective zones. Maximum current load for each zone is designed to handle up to 6 actuators with a power of 2W each. With more actuators in one zone, an additional relay should be used to make sure that actuators output will be not overloaded.

INSTALLATION

1. Remove the top cover of the control box.

2. Remove the appropriate piece of insulation from the wires

3. Connect the wires in accordance with the connection description.
   Refer to the sticker under the top cover.

4. After making sure all wires are properly connected, mount the top cover and turn the wiring centre to the 230 V power supply – the red “Power” diode will light up.
