For Home Owners
General
Indicator lamp for operation
When the green light comes on, the flue gas thermostat’s
set temperature has been reached.
Flue gas thermostat
This thermostat starts and stops fans and any charge
pumps during lighting and extinguishing phases. The
thermostat is delivered connected for charge control by
thermal valve. i.e. the flue gas thermostat only starts and
stops the flue gas fan. To prevent stationary losses via
VEDEX 3300, reconnection to charge control without
thermal valve is recommended. The flue gas thermostat,
together with the boiler thermostat, then starts and stops
the charge pump.
Max. thermostat
This thermostat stops the fan when the boiler temperature
exceeds the set value.
Charge thermostat
Thisthermostat starts and stops the charge pump at the
set value.

Boiler temperature gauge
The operating temperature of the boiler is indicated on the
gauge which is graduated 0–120°C. It shows the tempera-
ture of the boiler water level with the flow line connection.
Boiler pressure gauge
The boiler’s pressure is displayed here. The gauge is gradu-
ated 0 - 4 bar with a red mark at 1.5 bar.
Max. permitted pressure is 1.5 bar at 100°C.
For a closed system, the operating pressure varies during
operation depending on the installation’s varying tempera-
ture.
