Igniting
When the fan has reached the start rpm, the burner relay will be ignited by means of
electrical sparks. During the ignition, code
not ignite, a new attempt will be made after approximately 15 seconds. If after 4 ignition
attempts, the boiler controller has still not been ignited, the controller will go into down-
time.

CH operation
An on/off thermostat, an OpenTherm thermostat, an outdoor sensor or a combination
thereof can be connected to the controller (see par. 10.3)
When there is a heat request from a thermostat, after the fan has started running (code
3 ), the ignition will take place (code
During CH operation, the rpm of the fan and therefore the power of the unit can be
adjusted so the temperature of the CH water to the required CH supply temperature can
be controlled. If an on/off thermostat has been connected, this will be the CH supply
temperature set on the display. In case of an OpenTherm thermostat, the required CH
supply temperature is determined by the thermostat. In case of an outdoor sensor, the
required CH supply temperature is determined by the fuel line programmed in the boiler
controller. For the last two situations, the temperature set on the display is the
maximum.
During CH operation, the requested CH supply temperature will be displayed on the
operating panel.
The CH supply temperature can be set between 30 and 90°C (see par. 7.1). Caution:
for a low temperature system, a lower maximum setting may be required than the
standard setting of 80°C.
You can press the service button during CH operation to read the actual CH supply
temperature.
If the tap comfort function is switched on (see code
of less than 40 degrees will be generated.
