Cooler Pump Control - It is required for all chillers that the cooler pump control be utilized unless the chilled water pump runs continuously or the chilled water system contains a suitable concentration of antifreeze solution. When the Cooler Pumps Sequence is configured, the cooler pump output will be energized when the chiller enters an ON mode. The cooler pump output is also energized when certain alarms are generat- ed. The cooler pump output should be used as an override to the external pump control if cooler pump control is not utilized. The cooler pump output is energized if a P.01 Water Exchanger Freeze Protection alarm is generated, which provides addition- al freeze protection if the system is not protected with a suitable antifreeze solution
To configure this option with the Navigator display
Circuit/Compressor Staging and Loading
The dual chiller control algorithm has the ability to delay the start of the lag chiller in two ways. The Lead Pulldown Time parameter Lead Pulldown Type, LPUL is a one-time time delay initiated after starting the lead chiller, before checking whether to start an additional chiller. This time delay gives the lead chiller a chance to remove the heat that the chilled water loop picked up while being inactive during an un- occupied period. The second time delay, Lead/Lag Delay Lag Start Timer, LLDY is a time delay imposed between the last stage of the lead chiller and the start of the lag chiller. This pre- vents enabling the lag chiller until the lead/lag delay timer has expired

SPACE TEMPERATURE RESET - The control system is also capable of temperature reset based on space temperature SPT. An accessory sensor must be used for SPT reset 33ZCT55SPT. The Energy Management Module EMM is also required for temperature reset using space temperature

Switch Controlled Current Based - If using 2-step de- mand limit control, an energy management module must be installed. One-step demand limit control does not require the energy management module. Four parameters for 1-step switch control must be configured. For 2-step control, five parameters must be configured. The parameters are the type of Demand Limit Selection Demand Limit Type Select, DMDC, the setting for Switch Limit Set Point 1 Switch Limit Setpoint 1, DLS1, the setting for Switch Limit Set Point 2 Switch Limit Setpoint 2, DLS2, the Current Limit Select Current Limit Select, CUR.S, and the Compressor Current limit at 100% signal, Current Limit at 100%, CUR.F

Criteria for Trip - The criterion is tested when the circuit is ON. If the circuit operates and if more than 8 successive circuit capacity decreases stop the compressor have occurred because of low suction temperature protection overrides, the circuit alarm will be tripped. If no override has occurred for more than 30 minutes, the override counter will be reset to zero
