YK CENTRIFUGAL LIQUID CHILLER OptiView ... - Johnson Controls

Cycling Offset - Shutdown
Defines the leaving chilled liquid temperature at which
the unit will shutdown on a 'LEAVING CHILLED LIQUID
- LOW TEMPERATURE'. The 'OFFSET' (below
'SETPOINT') can be programmed between 0.56°C
(1°F) and 35.6°C (64°F) to a minimum cut-out of 2.2°C
(36°F) for water cooling applications (1.1°C (34°F) with
Smart Freeze enabled) or -14.4°C (6°F) for brine/glycol
applications.
When the programmed leaving chilled liquid
temperature 'SETPOINT' is changed, the shutdown is
fixed at of 2.2°C (36°F) for water cooling applications
(1.1°C (34°F) with Smart Freeze enabled) or -14.4°C
(6°F) for brine/glycol applications for the next ten
minutes.
The shutdown will then revert to the 'SETPOINT' plus
the 'OFFSET' after ten minutes has elapsed.
Cycling Offset - Restart
160-54-OI-GB0 7
Defines the leaving chilled liquid temperature at which
the unit will restart after a 'LEAVING CHILLED LIQUID -
LOW TEMPERATURE ' shutdown. The 'OFFSET'
(above 'SETPOINT') can be programmed between 0°C
(0°F) and 21.1°C (70°F) to a maximum restart of 26.7°C
(80°F). This 'OFFSET' can be used to reduce unit
cycling by delaying the restart until the cooling load has
increased dramatically.
