(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.
(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.
(0.0 to 25.0) The condenser delta-T furnished by the
condenser manufacturer.
(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.
(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.)
(List box: Yes, No) Whether the condenser inlet
temperature is to be monitored.
[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.
