York 152, YLCC 42/62/82/102/112, YLCC-h, 122 manual Alarms and messages

(a)Units with single-phase axial or centrifugal fans with speed control. Phase cut-off modules by triac are used.The val- ues indicated do not match the real voltage applied, but rather a variable internal voltage of the controller.

Units with three-phase centrifugal fans without speed con- trol. Set parameter F3 = 0 and close jumpers P1 and P6 of the base and expansion plates.

(b)Units with single-phase axial or centrifugal fans with speed control. Phase cut-off modules by triac are used.The val- ues indicated do not match the real voltage applied, but rather a variable internal voltage of the controller.

Units with three-phase centrifugal fans without speed con- trol. Set parameter F4 = 166 and close jumpers P1 and P6 of the base and expansion plates.
