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)
.
