Introduction
ECB08M230 control box is the main element of the underoor 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 dierent 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.

Thisproductcomplies with the essential requirementsand other relevantprovisionsof the following
EU Directives: EMC 2014/30/EU, LowVoltage Directive LVD 2014/35/EU, RoHS directive 2011/65/EU.
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
ECB08M230
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

Control Box description
1. Cartridge fuse 5 x 20 mm T6,3A
2. Power supply (AC 230V)
3. Pump control output (AC 230V)
7. LED diodes indicators for the operation status of the pump,
boiler and control box power supply connection
8. LEDs 1 to 8 informing about the operation of zones 1-8
4.
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 o immediately, when none of the zones
sends a signal for heating.
2. 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.
1. 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.

The PUMP OUTPUT is used to power the circulation pump in the heating system.
It is a 230V AC voltage output with a maximum load capacity of 3A. The pump is
connected directly to the contacts. The output is turned on (the pump starts) always
after 3 minutes from the moment of receiving a heating signal from any thermostat
connected to the wiring centre. The output is turned o (the pump stops) as soon as
the last thermostat stops reporting heat demand.
3. Pump control output (AC 230V)
When the Pump/Valve control output is
activated, the pump status LED shows a
constant green light.
When the BOILER control output is
activated, the boiler status LED shows a
constant green light.
PLEASE NOTE: Before starting the installation, disconnect the 230V power
supply!
