Attachment of regulation and control elements
The boiler is delivered to a consumer equipped with basic regulation and control elements.
Attachment of these elements is indicated on the chart of connection. We recommend to extend
the regulation of boiler with other regulation elements which enable more comfortable and
economic operation. Each pump in the system must be controlled by an individual thermostat so
as the boiler was not undercooled on the inlet of return water under 65°C. Attachment of these
elements can be suggested by a designer due to specific conditions of the heating system.
Electric installation together with the additional equipment of the boiler must be done by a
specialist according to valid standards.
Connecting the boiler to the mains
The boiler is connected to the net of 230 V, 50 Hz by a supply cord and plug. The voltage is of M
type and when replaced, the same type must be used by a service organization. The appliance
must be located in such a way that the plug is within the reach of the attendance.
(according to STN EN 60 335-1 + A11:1997). Connection of a socket must suit to STN 33 2000-
4-46, the socket equipped with centre contact pin connected to the conductor. Any multicontact
plugs or extension cables are not allowed. After connection to the net, the power supply must be
approachable because of safety.
