Chilled Water Reset (CWR)
Functional Description
The UC800 shall reset the chilled water temperature setpoint based on return water temperature or outdoor air
temperature. The Return Reset and Outdoor Reset functions are standard.
The chilled water reset settings are as follows:
1. Reset Type – The following options are selectable: No Chilled Water Reset, Outdoor Air Temperature Reset, Return
Water Temperature Reset, or Constant Return Water Temperature Reset.
2. Reset Ratio – For Outdoor Air Temperature Reset, both positive and negative reset ratios will be allowed.
3. Start Reset
4. Maximum Reset – The maximum resets shall be with respect to the chilled water setpoint.
All parameters shall be factory set to a pre determined set of values. Field adjustment of two, three and four above
is expected to be very infrequent. Pre determined factory settings shall be set for all Reset Types.
Variable definitions:
CWS – Arbitrated chilled water setpoint, before any reset has occurred
CWS’ – Active chilled water setpoint, includes the effect of chilled water reset
CWR – Amount of chilled water reset (also called Degrees of Reset).
The above quantities are related by the equation:
CWS’ = CWS + CWR
or
CWR = CWS’ – CWS
With the chiller running and any type of chilled water reset enabled, CWR is allowed to change at a maximum rate of
-17.2°C every 5 minutes until the actual CWR equals the desired CWR. When the chiller is not running, actual CWR
shall be set equal to the desired CWR within one minute (no maximum rate is in effect).
If Chilled Water Reset is disabled, desired CWR is 0.
Additional variable definitions:
RESET RATIO – User adjustable gain
START RESET – User adjustable reference
TOD – Outdoor air temperature
TWE – Evaporator entering water temperature
TWL – Evaporator leaving water temperature
MAXIMUM RESET – User adjustable limit providing the maximum amount of reset.
The equations for each type of reset:
Outdoor Air Temperature Reset
CWR = RESET RATIO * (START RESET – TOD)
With limits:
CWR > 0
CWR < Maximum Reset
Return Water Temperature Reset
CWR = RESET RATIO * (START RESET – (TWE – TWL))
With limits:
CWR > 0
CWR < Maximum Reset
Constant Return Water Temperature Reset
CWR = 100% * (Design Delta Temperature – (TWE – TWL))
With limits:
CWR > 0
CWR < Design Delta Temperature
