Optional FeaturesControls/Instrumentation<strong>Water</strong> Flow SwitchA field-installed and wired flow switch in the chilled water, or both chilled water and condenserwater, piping to help prevent evaporator freeze-up under low- or no-flow conditions. Terminalsare provided in the unit control center for field hookup of the water flow switch(s). Installationof a chilled water flow switch is mandatory.<strong>Water</strong> Flow Switch (Factory-Installed, Solid State)A solid state flow switch located in the evaporator outlet nozzle is factory installed and wired. Inaddition to the electronic output signal, the switch has an LED display to visually indicate thepresence of flow. It eliminates the need for a field-installed switch.The 24 Vac powered flow sensor is a solid state alternative to mechanical switches for sensingthe acceptable flow rate of water. These compact units are constructed of corrosion-resistantmaterials and 316 stainless steel parts and installed directly through a ¼ inch NPT into the flow.The flow sensors operate on the calorimetric principle. The sensors use the cooling effect of aflowing fluid to provide reliable flow rate detection of liquids over a very wide flow range. Theamount of thermal energy that is removed from the tip determines the local flow rate and whenit exceeds a setpoint it changes the output-state.BAS InterfaceDaikin McQuay’s Open Choices feature consists of a factory-installed communicationmodule for LONMARK, Modbus, or BACnet with RS-485 port and Ethernet, standardprotocols.Remote Communication ModuleA remote interface panel, field wired from the chiller controller to the remote pane to provideremote viewing of unit operation, clearing of alarms and changing of setpoints. See page 9 fordetailsElectricalPower Connection OptionsThe standard connection is multi-point power connections (two) to power blocks with nodisconnect switches or circuit breakers. A compressor isolation circuit breaker for each circuit isnot available on multi-point arrangements and is included on all single point arrangements.There are seven options as shown below and summarized in Table 35 on page 52. Interruptratings are summarized in Table 36.Disconnect Switches, Multi-PointA non-fused disconnect switch for each circuit (two), with through-the-door handle. Thedisconnect switches are properly sized for model and voltage required. No compressor isolationcircuit breakers are included.High Interrupt Disconnect Switches, Multi-PointA high interrupt current rating, non-fused disconnect switch for each circuit (two), with throughthe-doorhandle. The disconnect switches are properly sized for model and voltage required. Nocompressor isolation circuit breakers are included.Catalog WGS-1 WGS 130A – 190A 51
