4.1. Pressure fan work parameters.
Fan power [Π100] – this value defines power of the fan. When „Πr”parameter is set to
„0-10” this is the maximum power of the fanwhich can be achieved during automatic
fan control.
Minimum fan power [n 40] – lowest fan power which can be used when automatic
fan speed control is on and when fan speed is gradually increased during boiler start.
Fan speed decrease coefficient [Πh 2] – this parameter influences the way fan
speed is reduced when boiler tremperature is approaching its desired value. E.g.
setting this parameter to 2 means that when the controller is in WORK mode and
