All lines that are displayed in the intermittent form in the diagram of external connections are
the conductors which should be installed by the technician when connecting the external
devices onto the automation system of the boiler. All the connections of the additional devices
are performed by the technician through connectors located at the rear of the boiler. One three-
pole connector serves for the connection of the room thermostat as shown on the label the
connector itself.
Seven-pole connector is connected to the power cable, while through another three-pole
connector (next to seven-pole) the circulation pump is connected.
For the room thermostats it is important to be battery-powered on, i.e. they should
not have any supply of the voltage of 220 V. On the thermostat for the connection NC
is used (normally closed contact)
