The Standard AIREX panel board
operates automatically the shut off of
the fan and the recirculation pump, if
the boiler temperature (after 30 minutes
from the closing of the loading door, for
the boiler ignition purposes) does not
reache 65 °C (minimum temperature).
The panel board (and the cycle) can
be reset only after opening the loa-
ding door for a new ignition, or by the
switching off and on of the main switch
pos. 11.
The same logic of the panel board will
stop the fan and the recirculation pump
at the end of the loaded wood.
The pump system will operate only after
passing the minimum temperature in the
boiler of 65 ° C.
If the temperature decreases below the
threshold of 65 °C, the pump system will
be shut down.
TheD.H.W. storage tank loading pump
will work with priority on the C.H. pump.
Water production for heating circuit with temperature controlled on the system by mixing valve with manually control.
Production of hot water boiler with a coil type heat exchanger or plate heat exchanger with separate installation and
dedicated loading pump.
