Application example 1 Vitolig 300 with DHW cylinder and one or two heating circuit(s) with mixer
The heating circuits with mixer and the
DHW cylinder are controlled by the
heating circuit controller of Vitolig 300.
Vitolig 300 will only be started if there is a
demand from the DHW cylinder or from
the heating circuit. The timer program for
heating operation and heating up the
DHW cylinder is set at the remote control
unit of the heating circuit controller. The
heating circuit pump is switched via the
heating circuit pump logic, provided there
is a heat demand.
Upon demand, the boiler is operated with
the required boiler water set temperature
or the minimum temperature of 60
º
C. A
DHW demand which is given priority
causes the heating circuit pump to be
switched off and the mixer to be closed.
When the DHW cylinder reaches its set
temperature, the system changes over to
the heating circuit.
Any demand is transferred to Vitolig 300.
The boiler has automatic ignition. The
DHW circulation pump or the heating
circuit pump will only be switched on,
and the mixer set into control mode,
when the minimum temperature of 50
º
C
is exceeded.
The boiler is switched off, if neither DHW
cylinder nor heating circuit make any
more demands.
The pellet feed control unit enables the
filling of the pellet container for each day.
