Room thermostat (RT entry) –
when the voltage free contact gets opened the boiler
will stop heating. The entry is responsible for boiler's control depending on the room
temperature (room thermostat connection details – section 'Installation ', sub clause 7).
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 different heat source.
WE-019/01 cylinder water temperature sensor (Thw entry) -
for connection details
please, refer to the figure. If there is need to extend the wire- it is necessary to make
it as short as possible. 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 and they must not
go around other electric wires.
Note! To activate sensor and DHW cylinder heating function, please follow the
instructions in section „Advanced settings”.
Three way divert valve (TWV entry) -
the valve has to be connected in accordance
with the diagram on page 18-19 depending on the model. Note: in order to activate
DHW function one must follow the instructions in the section 'Advanced settings'.
WE-027 outside temperature sensor (Text entry) -
for connection details please, refer to
the figure. If there is need to extend the wire- it is necessary to make it as short as possible.
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 and they must not go around other
electric wires. It is recommended to mount the sensor on the northern or north-west
facade of the building away from windows and exhaust fans.
Note! If outside temperature sensor hasn't been connected then it is necessary
to switch off weather compesation (heating curve coefficient, weather
compensation switch off > C=0 )
