Chilled Water Reset (CWR)
How many Degrees of Reset will there be?
Degrees of Reset = Reset Ratio*(Start Reset - (TWE-TWL))
Degrees of Reset = .5*(-6.67-(18.3-7.22))
Degrees of Reset = -8.875
If:
Reset Ratio = 70%
Start Reset = -6.67°C
TWE = 15.55°C
TWL = 11.67°C
Maximum Reset = -10°C
How many Degrees of Reset will there be?
Degrees of Reset = Reset Ratio*(Start Reset - (TWE-TWL))
Degrees of Reset = .7*(-6.67-(15.55-11.67))
Degrees of Reset = -18.12

Note: This graph assumes a Design Delta Temp of -12.2°C.
Diagnostic
If any sensor measurement needed to perform the currently selected chilled water reset type is invalid due to loss of
communication or sensor failure, the desired CWR will be set to 0. The actual CWR is subject to maximum rate limits
described earlier.
