Function
Start with the boiler cold.
Set the main switch, 2
0, to the ON-position – the green area must be
visible.
Set the thermostat, “FAN STOP”, 21, to 120°C. The thermostat
detects the flue gas temperature.
Press “FAN START”, 22, the time relay, 24, is activated and the fan
starts.
When the time set for the time relay, 30 minutes, is reache
d, the
contact changes, which means that the fan and the charging pump
for the accumulator system are controlled by the thermostat, 21.
When the firewood is burnt out and the flue gas temperature falls
below the value set for the thermostat, 21, the fan and charging pump
stop running.
If the boiler temperature exceeds 105°C, the overheating protection is
triggered. The fan stops running and the charging pump continues to
operate. If the overheating protection, 25, is triggered, the “ALARM”
indicator, 26, is lit.
An thermostat limits the boiler’s working temperature.
