For the Navigator™ display, the status of the operating
modes can be found in the MODE submenu under the OPER-
ATING MODES menu. The 6 top priority operating modes are
displayed in MD01 through MD06. To view the modes with
the Navigator™ display:
See Table 37 for a list of operating modes.
STARTUP DELAY IN EFFECT — This mode is checked
for when the unit is started. This mode is active when the Min-
utes Off Time (Unit Off to On Delay, DELY) timer is active.
The unit will not start until the timer has expired. The mode
will terminate when the timer expires.
SECOND SETPOINT IN USE — This mode is checked for
when the unit is ON. The mode is active when Cooling Set-
point 2 (Cooling Setpoint 2, CSP.2) or Ice Setpoint (Cooling
Ice Setpoint, CSP.3) is in use. While in this mode, the Active
Setpoint (Current Setpoint, SETP) will show the CSP.2 or
CSP.3 value.
While in this mode, the unit will operate to the Cooling Set-
point 2 (CSP.2) or Ice Setpoint (CSP.3). The mode will termi-
nate when the Cooling Setpoint 2 (CSP.2) or Ice Setpoint
(CSP.3) is no longer in use.
RESET IN EFFECT — This mode is checked for when the
unit is ON. The mode will be active when Temperature Reset
(Cooling Reset Select, CRST) is enabled either by CRST=1
(Outside Air Temperature), CRST=2 (Return Water), CRST=3
(4-20 mA Input), or CRST=4 (Space Temperature) and reset is
active.
While in this mode, the Active Setpoint (Current Setpoint,
SETP) will be modified according to the programmed infor-
mation and will be displayed as the Control Point (Control
Point, CTPT). The mode will terminate when the Temperature
Reset is not modifying the active leaving water set point, caus-
ing SETP to be the same as CTPT.
DEMAND LIMIT ACTIVE — This mode is checked for
when the unit is ON. The mode is active when Demand Limit
(Demand Limit Type Select, DMDC) is enabled either by
DMDC=1 (Switch), DMDC=2 (4-20 mA Input), or the Night
Time Low Sound Capacity Limit (
Capacity Limit, LS.LT).
The Active Demand Limit Value (Active Demand Limit
Val, LIM) will display the current demand limit according to
the programmed information and the unit’s capacity will be re-
duced to the amount shown or lower. The mode will terminate
when the Demand Limit command has been removed.
RAMP LOADING ACTIVE — This mode is checked for
when the unit is ON. The mode is active when Ramp Loading
(Ramp Loading Select, RL.S) is enabled and the following
conditions are met:
1. The leaving water temperature is more than 4° F (2.2° C)
from the Control Point (Control Point, CTPT), and
2. The rate of change of the leaving water temperature is
greater than the Cool Ramp Loading (Cooling Ramp
Loading, CRMP).
The control will limit the percent capacity increase until one
of the two conditions above are no longer met, then the mode
will terminate.
COOLER PUMPS ROTATION — This mode is checked for
whether the unit is ON or OFF. The mode is active when the
Cooler Pump Sequence (Cooler Pump Run Status,
PUMP=2) (2 Pumps Automatic Changeover) and the Pump
Rotation Delta Timer (Pump Auto Rotation Delay, ROT.P)
have expired.
The control will switch the operation of the pumps. The
lead pump will operate normally. The lag pump will be started,
becoming the lead, and then the original lead pump will be shut
down. This mode will terminate when the pump operation has
been completed.
