Start up process
During heat demand the pump is activated by the controller. After zero-check of the air pressure switch
the fan speeds up to airflow-check fan speed. Once the air pressure switch is closed the fan goes to igni-
tion fan speed.
After 5 seconds pre-purge on ignition fan speed, the water pressure sensor, gas pressure switch and si-
phon pressure switch are checked. When all pressure switches are closed and the water pressure is OK,
the ignition is released.
The temperature control and safeguarding is done with the use of NTC’s. Data coming from these NTC’s is
processed by the controller (Maxsys) that takes care of control and safe-guarding of the boiler.
“Slow start” principle
Standard setting of the boiler involves the “slow start” principle in order to avoid the boiler and installa-
tion to heat up too quickly.
After “zero check” APS and closure APS with pre purge, ignition starts. After a stabilizations time the boiler
modulates down to low capacity and stays there for 1 minute. Subsequently the boiler speeds up at a
rate of 4 °C/min till set capacity or set temperature has been reached. Once heat demand has finished the
boiler will stop after its set pre-purge period.
