1: Cooler pump control. This item can be forced On or Off if the unit is in CCN mode and if the CHIL_S_S is
disabled. If the unit is not in CCN mode the forced value shall be unused and the regular calculation shall be
used. Forced value and force code shall appear in the OPTIONS Points Display table only if the unit is under CCN
control and if CHIL_S_S is disabled.
If PUMP#1 is forced, no force shall be allowed on PUMP_2 and vice versa.
2: Condensing Setpoint. This item can be forced. If the unit is in CCN mode, the forced value shall be used instead
of the real control point calculation. If the unit is not in CCN mode the forced value shall be unused and the
regular calculation shall be used. Forced value and force code shall appear in the OPTIONS Points Display table
only if the unit is under CCN control.
3: Condenser pumpcontrol. This item can be forced On but not Off. If the unit is in CCN mode, the forced value shall
be used instead of regular pump control point. If the unit is not in CCN mode the forced value shall be unused and
the regular calculation shall be used. Forced value and force code shall appear in the OPTIONS Points Display
table only if the unit is under CCN control.
4: Electrical box Thermostat. This item indicates the electrical box thermostat and network power reverse phase
detection status (wired internally in series 16a and 16b on PD4-BASIC BOARD). These contacts, when opened
will prevent the unit from starting.
5: This output is energized when a contact failure is reported by any SCPM board
