Room thermostat (RP entry)
– when the voltage free contact gets opened the boiler
will stop heating. The entry is responsible for boiler control depending on the room
temperature. (room thermostat connection details – page 4, sub clause 7).
WE-019/01 Cylinder water temperature sensor (Tzas entry-refers to EKCO.LN2 and
EKCO.L2 model) – for connection details please, refer to the gure.
If it is necessary,
you can extend the wires, however, please remember that the shorter the wires
the better. If the wire is too long there may occur disturbances and it may not work
properly. The wires should not run close to mains cables, they must not go around
other electric wires.
Important. To activate the sensor and DHW cylinder heating, please follow the in-
structions in section „ADVANCED SETTINGS”. Set up the temperature of heating
medium (50 - 85°C) and select „ti” as a way of temperature measurement in cylinder.

DHW Cylinder thermostat (Tzas entry- refers to EKCO.LN2 and EKCO.L2 model) –
Kospel suggests to use the VCZMH6000E valve with the VC6013ZZ00 servo-motor. The
three-way valve control is performed by applying 230V on the brown wire or the black
wire (blue is the neutral wire). Voltage on the valve through the brown wire will switch the
valve to a position, where the pass between the „AB” inlet and the „B” outlet gets opened.
Shall voltage be passed to the black wire, the valve will get switched to the position in
which the channel between the „AB” inlet and the „A” outlet will be opened. The „AB”
inlet and the „A” and „B” outlets are marked on the valve An entry „B’’ is to supply the
central heating system and the entry „A’’ is to supply the cylinder. Important. To activate
the cylinder heating please follow the instructions in the „ADVANCED SETTINGS” sec-
tion. Set up the temperature of heating medium (50 - 85°C).
Master appliance (NA entry) – you can limit the power used, i.e. the boiler can be
switched off while another appliance consumes electricity. To do it, an electrician should
install in line an extra open contact to the NA entry (voltage free entry), so that when a
master appliance gets on, the contact will be opened the boiler switched off. When the
NA contact gets opened, heating will get off and the pump stopped. The EKCO.LN2
and EKCO.L2 model may also work as second boiler. If it is so, the master boiler by
opening the NA entry will stop heating of EKCO. However, the mode of the three-way
valve control stays on so a DHW cylinder is charged by the heat from the master boiler.

Special start-up procedure (when the system is lled with an antifreeze solution)
A ow rate reading error may occur if you start-up the unit at low ambient temperature.
This error may occur because the physical properties of antifreeze solution. If the H
indicator ickers and the cut-off valves are opened you have to close NA and RP contacts
which will automatically start the special start-up procedure. As a result, the medium will
be warmed up to temperature that enable you to read the ow rate correctly. The duration
of procedure depends on both the installation capacity and the temperature inside the
installation. When a control panel display shows selected parameters alternately and
marks („-”, „--”) it means that the procedure is started. The procedure will close auto-
matically and the unit will start normal operation once the minimal ow rate is reached.

1. Disconnect the NA contacts or detach
temperature regulator from the boiler.
2. Check if the appropriate system
installation pressure is reached (see
the „TECHNICAL DATA” section).
By using or buttons whilst
the control panel is off, the pressure
value will be displayed. When the
installation pressure is too low The
„A’’ indicator ickers (see „Operating’’
section). This doesn’t concern open
vented system installations.
3. Set the pump control to manual
mode, see the „Advanced settings”
section.
4. Switch the boiler on (press but-
ton).
5. Check the pump is set to the correct
mode (see table below). To do this,
press button for no more than 2
seconds. The LED’s should signal an
operating mode at the place pointed
by arrow.
6. If the LEDs are signaling a different
operating mode than recommended
in the table below, set the appropri-
ate mode according to the following
instructions: press button for
longer than 2 seconds, but less than
10 seconds (LED’s will start to ash),
the pump then switches to the set-
tings mode. LEDs glows to indicate
the current settings. To change the
settings of the pump in accordance
with the table below, you can set the
right combination of glowing LEDs by pressing the button. Once LED combi-
nation is set correct, by not pressing the button for 10 seconds the pump will
remember this setting and will exit from setting mode back to performance view.
Note: holding button for more than 10 seconds will enter the pump into
key lock mode. this prevents the user from altering the pump settings. To
remove the key lock the pump settings and allow the pump settings to be
changed, hold button again for more than 10 seconds.
7. Ensure adequate ow through the boiler is reached (the „H” indicator is on with
a constant light). The pump should self vent after a short period of running. if
