4.2.1

Gas/air regulation

The boiler is equipped with a casing that also serves as an air box. The
fan draws in the combustion air. The gas is injected into the venturi and
mixed with the combustion air. The fan speed is controlled on the basis of
the settings, the heat demand and the prevailing temperatures measured
by the temperature sensors. The gas/air ratio control ensures an accurate
mixture of the required amounts of gas and air. This provides optimum
combustion over the entire heat input range. The gas/air mixture goes to
the burner, where it is ignited by the ignition electrode.
4.2.2

Control

On/off control
The heat input varies between the minimum and the maximum values
on the basis of the flow temperature set on the boiler. It is possible to
connect a 2-wire on/off thermostat or a power stealing thermostat to the
boiler.
Modulating control
The heat input varies between the minimum and the maximum values
on the basis of the flow temperature determined by the modulating con­
troller. The boiler output can be modulated with an appropriate modulat­
ing controller.
Analogue control (0 - 10 V)
The heat input varies between the minimum and the maximum values
on the basis of the voltage present at the analogue input.
4.2.3

Circulation pump

The boiler does not have a built-in pump, but does have a built-in pump
switch. A circulating pump can be installed on the connector of the stand­
ard control PCB. This can be an on/off pump or a modulating pump (with 0
- 10 V control).
The pump settings can be changed.
