Dynamic Setpoint Condenser - Emerson XC1008D Installing And Operating Instructions

1. with AUX temper. < O3
2. with AUX temper. > O4
3. with O3 < AUX temper < O4 ==> SEtC1 < "Real SEtC1" < O2

O5 Dynamic compressor set point function enabled - circuit 2
no = standard regulation
yES = the SETC2 varies according to the setting of O6, O7, O8.
WARNING the dynamic set point requires a dedicated probe, so it's necessary one of the aux probes
is set for this function in other words AI17 or AI20 or AI23 or AI27 has to be set as otA2.
NOTE: if more than one probe is used for the optimization of the suction set point, only the higher
temperature is considered.
O6 Maximum compressor set point - circuit 2
compressor set point used in the dynamic set point function. The measurement unit depends on C45
parameter.
O7 External temperature for maximum set point O6 - circuit 1
the temperature detected by the external AUX probe, at which the maximum set point is reached.
O8 External temperature for standard set point– circuit 2 (O7÷150°C O7÷302°F)
1. with AUX temper. < O7
2. with AUX temper. > O8
3. with O7 < AUX temper < O8 ==> SEtC2 < "Real SEtC2" < O6

O10 Minimum condenser set point - circuit 1 (F2÷SETF1)
O11 Differential for condenser dynamic set point –circuit 1 (-50.0÷50.0°C; -90÷90°F). The way of
working of this algorithm is explained in the following exemplum.
