In the table above, the first column represents example display indications, in
the next columns there are: parameter description, minimum and maximum
values allowed to set, step of the parameter during the setup. The last column
shows factory defaults to which you can return by choosing [Prod] option.
(1) Fan work parameters
Fan power [ Π 100] - this value defines power of the fan. When " Π r" parameter is
set to "0-10" this is the maximum power of the fan which can be achieved
during automatic fan control.
Automatic fan speed control [
Π r 1] - it is on, when this parameter is set to "0-10"
and causes automatic fan speed decrease when temperature of water in the
boiler reaches desired temperature. If this parameter is set to "-", the fan
automatic smooth speed control is disabled and the fan can work with power set
by "
Π " parameter. Setting parameter value in range from 0 to 10 means time in
minutes of the smooth fan speed increase from 40% to value of " Π " - for smooth
boiler start.
