Installation notes
EKCO.MN3 boilers are equipped with an expansion vessel (capacity: 5l, pressure:
1,5 bar). 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.

Temperature sensors
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.
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.
External adjustment of selected room temperature (inlet FN)
Closing FN contact shifts boiler’s work to the mode of maintaining the temperature
previously set in the conguration menu [CONFIGURATION> ENTRY FN].
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. 8
and 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.

circulations or older heating systems with pipes of larger diameters, as well as
for all applications with constant characteristics.
In the regulation mode (VARIABLE P. the pressure difference produced by the
pump is maintained at the level of settings changing linearly between 1/2H and

This regulation type is recommended for heating systems with heaters, thanks
to which ow noise in thermostatic valves is reduced.

TURBO function
If the facility is cold and if it is necessary to heat it up quickly, there is a possibility to
turn on the TURBO function. This function, when conditions to turn on the heating are
fullled, starts central heating installation with maximum parameters and continues until
required temperature is reached in a room. This function can start automatically when
room’s temperature falls down by the set room temperature hysteresis.
Automatic work is set in menu CONFIGURATION > AUT. TURBO MODE. Selection of
„Hot water tank- NO” will result in switching off hot water heating priority for the time of
using Turbo function. In menu PARTY/ HOLIDAY/ MANUAL it is possible to turn on this
function manually (without hot water heating up priority), in condition that the room’s
temperature is lower than the programmed one. Sensor Tr is required to turn on Turbo
function
Frost protection
Frost protection is activated automatically during stand- by and HOLIDAY mode
(power mode only on cylinder). It can be activated in the time frames for installations of
CH and DHW or during the HOLIDAY mode. The installation protection will be activated
if the outside temperature falls below 2°C or the room temperature drops below 7°C.
In this case, the CH circulation will be activated.
The temperature will be set according to the heating curve estimations or manually set
according to the regulation. Tr sensor is required to activate this function.
The function is disabled when the boiler is controlled by an external room controller or
other external sensor connected to the RT input. In this case, the frost protection mode
must be enabled on the external controller, the boiler will maintain temperature set
manually or based on heating curves.
If there are no dened time frames, then after
selecting „new” the time frame 00:00am to
23:59pm will be set , which should be edited in
accordance with user’s needs.
The daily program will be saved to the boiler’s
settings by pressing the command „END”.
