38 AK2-SC 255 Reference Manual RS.8D.M1.22
Min sat. cond temp (0.0 to 200.0) The target minimum saturated condens-
ing temperature that the controller will strive to main-
tain. Target is calculated by adding outside temperature
and the condenser’s design temperature differential.
Max sat. cond temp (0.0 to 200.0) The target maximum saturated condens-
ing temperature that the controller will strive to main-
tain. Target is calaculated by adding outside tempera-
ture and the condenser’s design temperature differen-
tial.
Condenser Delta T (0.0 to 25.0) The condenser delta-T furnished by the
condenser manufacturer.
Target (0.0 to 500.0 for pressure sensors; 0.0 to 200.0 for
temperature sensors) The value that the control
algorithm will seek to maintain with the selected
strategy.
The next page has settings for high pressure bypass and for inverter control, if used.
The page is reached by using PG DN.
The screen looks like this:
The field information is as follows:
High pressure bypass (0.0 to 500.0) The pressure at and above which all
fans will be run, and at full speed if variable speed
motor control is used. (When high pressure bypass
occurs, a service technician is required to clear the
bypass by using the appropriate button in the status
screen.)
Monitor inlet temp (List box: Yes, No) Whether the condenser inlet
temperature is to be monitored.
Fan inverter control [Please see notes on Neutral Zone selection in the
section on the first condenser configuration screen.]
(List box:)
None: No variable speed drive is controlled.
