37Table 34 — Dual Slave Chiller Control Parameters for Series Applications with Touch Pilot DisplayNOTE: If pump control is configured to OFF, then LAG UNIT PUMPSELECT = 1. If pump control is set to any other value, then LAGUNIT PUMP SELECT = 0. This configuration must be set consis-tently for both master and slave chillers.Table 35 — Dual Slave Chiller Control Parameters for Series Applications with Navigator DisplayNOTE: If pump control is configured to OFF, then LAG UNIT PUMPSELECT = 1. If pump control is set to any other value, then LAGUNIT PUMP SELECT = 0. This configuration must be set consis-tently for both master and slave chillers.DUAL CHILLER PUMP CONTROL FOR SERIESCHILLER APPLICATIONS — Pump control for series chill-er applications is controlled by the master chiller only. Thecontrol of the slave chiller is directed through commands emit-ted by the master chiller. The slave chiller has no action inmaster/slave operations. The slave chiller only verifies thatCCN communication with the master chiller is present. See theDual Chiller Sequence of Operation section on page 68.Night Time/Low Noise Operation — The Com-fortLink™ controls have the ability to lower the sound level ofthe machine by reducing the number of fans that are running,provided that the conditions are acceptable. Reducing the num-ber of running fans also limits the capacity. Three parametersmust be configured for this operation. A start and end time forthe mode of operation is required and an optional capacity limitset point must also be configured.DISPLAY NAME PATH LINE NO.
