Carrier 09DK054-094 - Manual (Page 33)

The fan cycling pressure switch controls the fans as fol­
lows; Fans 3 and 4 are on above 260 ± 15 psig (1793 ±
103 kPa) and off below 160 ± 10 psig (1103 ± 69 kPa). If
pressure is rising between 160 psig (1103 kPa) and 260 psig
(1793 kPa), fans 3 and 4 are off. If pressure is falling from
260 psig (1793 kPa) to 160 psig (1103 kPa) fans 3 and 4
are on.
The air temperature switch controls the fans as follows;
On the 074-094 condensers, below 70 ± 3F(21.1 ± 1.7 C)
outdoor ambient, fans 5 and 6 are off; above 80 ± 3 F
(26.7 ± 1.7 C) fans 5 and 6 are on. Between 70 F (21.1 C)
and 80 F (26.7 C), whether fans 5 and 6 are on or off de­
pends on whether temperature is rising or falling. If the tem­
perature is rising from 70 F (21.1 C) to 80 F (26.7 C), fans
5 and 6 are off. If the temperature is falling from 80 F
(26.7 C) to 70 F (21.1 C), fans 5 and 6 are on.
