1.
This decision is only used for the water cooled chillers.
w
0 - no control
w
1 - condenser pump is based on the unit on/off status.
w
2 - condenser pump is ON when unit is ON (compressors are ON )
2.
This decision is only used for the water cooled chillers.
w
1 = water, 2 = medium brine, 3 = low brine
w
If condenser fluid type is brine, condenser pump will not be turned on for condenser freeze protection
function
3.
This decision allows to limit the setpoint of the customer (control point shall be higher than this value). It is
mostly used for brine application, as freezing condition depends on ratio on glycol and water.
4.
Used for cooler heater operation, this item is applied to outside temperature to determine the freeze
conditions (see cooler heater operation section).
5.
This item allows to use capabilities and functions based on CCN and clock..
6.
If enable, when chiller looses communication with the System Manager, it shall force the its CHIL_S_S
variable to «enable» and auto all other variables. Chiller restarts in stand alone mode with default setpoint .
7.
This decision allows to enter the entering temperature dead band for reclaim operation mode. See reclaim
operation description.
8.
This decision allows to enter the delay between two air cooled to reclaim injection sessions. See reclaim
operation description.
