Page 18: Operating Mode
Chapter 5 – Data Programming DIN NANO FSC OPERATING MODE 5.12 The condenser fans are controlled via a 0-10V analogue output and sideband-type adjustment. The LED icon (11) turns on to identify the fan condenser control. The regulation probe (terminal 23 /24) can be of two types: Flow pressure probe 4-20mA (parameter Pt = 0). -
Page 19: Energy Saving Mode
Chapter. 6 – Options DIN NANO FSC Adjustment probe value DECREASING (Graph nr.2): With adjustment probe values equal or higher than point (D), you will have a (iHv) analogue output. Between points (D) and (E), the analogue output will have a value proportional to the value of the adjustment probe starting from the maximum value of (iHv) up to the minimum value of the (iLv) parameter. -
