a qualied professional installer in accordance with the manufacturer’s instructions..
9. All installation work must be performed when the power and water supply is turned
off.
10. Electric installation should be equipped with residual current protective devices

Installation notes
EKCO.LN3 boilers are equipped with an expansion vessel (capacity: 5l, pressure: 1.5bar).
The expansion vessel is sufcient for following capacities of the heating system at given
temperatures of the medium and central heating system pressure.
Shall the capacity of the wet central heating installation be larger, an extra expansion
vessel should be installed on it as applicable in accordance with binding norm.

Tcyl – DHW cylinder temperature sensor
The connection cable of the temperature sensor should be as short as possible, it should
not be route it in close proximity to the power cords and do not twist around other cords. The
DHW cylinder temperature sensor can be optionally replaced thermostat, to do this switch
the input type Tcyl [CONFIGURATION> DHW TEMPERATURE> REGULATION> OUTSIDE]
and connect the NO contacts of the thermostat to the Tcyl terminals.
MA - Master appliance (entry MA)
In order to limit the power used, i.e. the boiler can cooperate with other appliances such
as an electric water heater. In order to do so, an electrician should install in line an extra
open contact to the MA entry (voltage free entry), so that when a master appliance gets
on, the contact opens, and the boiler switches off- it results in heating blockage and
pump’s standstill.
RT - room temperature regulator
Optional controlling the boiler operation depending on the room temperature. RT entry should
be activated [CONFIGURATION> ROOM TEMP.> TEMP. SENSOR> RT] - then opening
the voltage free contact will result in the switch off heating up the CH.
Three-way valve control (TWV entry)
Switching the boiler operation to central heating or heating water in the coil of DHW
cylinder is carried out using a three-way dividing valve with an actuator. Depending on
the model used, the device should be connected as shown on the diagrams, page no.
8and the manual of valve and servomotor. Note: In case of activation DHW cylinder you
should follow Service / Conguration - cylinder. Valves can be purchased in KOSPEL.

* Changes in the conguration menu are possible after entering an access code. When prompted
for an access code, turn the navigation dial to the required code and conrm the code by pressing
the dial. If you want to retract from the code request screen, hold the navigation dial or wait until
automatic return to main function screen.

● CENTRAL HEATING:
- MAX BOILER TEMP.: maximum CH temperature
Attention: adjustment of too high temperature parameters not compatible
with the type of building, central heating installation and building’s insulation
may lead to high exploitation costs.
- MAN the temperature of charging: set point of temperature ow CH.
- BOILER PROTECTION:
Yes - if the temp of inside’s sensor of boiler drops below 5, the circulation pipe
will be turned-on
No - protection turned-off. The need of conguration in case of central heating
installation lled in with non-freezing liquid.
● DHW CYLINDER:
- HW COIL TEMPERATURE: the setting of coil’s power.
- REGULATION: DHW cylinder temperature control - INSIDE> according to Tcyl
sensor/ OUTSIDE> according to external thermostat (not available when OUTSIDE
there are items in the menu: DHW CYLINDER TEMPERATURE, DHW CYLINDER
PROGRAM, DISINFECTION and MANUAL mode).
- CANCEL: turning off the function of DHW.
* If function DHW is turned-off, there will be only a possibility to turn-on.
● CIRCULATION:
switching the circulation "YES" or "NO",
● PUMP:
- PUMP OVER RUN: time when the pump is switched on for a short period of time
with a long standstill (blocking protection),
- AUTOMATIC MODE:
Yes - works depending on the demand,
No - continuous work.
- TYPE: pump's type,
- REGULATION:
CONST P. - constant pressure,

16
VARIABLE P. - variable pressure.
In the regulation mode (CONST P.)the pressure difference produced by the pump
is maintained at the constant set level in terms of performance to pump’s maximum
characteristics. This type of regulation is recommended for oor heating circula-
tions or older heating systems with pipes of larger diameters, as well as for all
applications with constant characteristics. In regulation mode (VARIABLE P.) the
pressure’s difference produced by the pump is maintained at the level of settings
changing linearly between 1/2H and H. Setting pressure differences decreases or
increases depending on the ow. This regulation type is recommended for heating
systems with heaters, thanks to which ow noise in thermostatic valves is reduced.
- VENTING: TURN ON / CANCEL
During venting procedure (10 min) the pump works alternately with a maximal and
minimal rotation speed. Thanks to this air bubbles are concentrated and easier to
remove from the installation.
- H MAX- pump’s raising height
● MAX RATED POWER: the setting of boiler’s rated power.
● PRESSURE SENSOR:
No - switching the control off- pressure control should be switched off only when
boiler works in the open installation.
Exit any menu item by pressing „END” or by pressing and holding the navigation dial.
When not operated by the user, main function screen will appear after about 3 min.
