Operation: Options for Fluid-Cooled Modules
Valve Types
Path: Main > Setup > System # > System Config > Valve Types
Set the type of valves installed in your piping system. Each valve can be either
Flow Switch. Set the location of the optional flow switch in this System. The flow switch detects whether there is adequate liquid coolant (water) flow to maintain coil operation.
The Flow Switch setting indicates where the flow switch is installed:
•DX, for the liquid line entering the heat exchanger (to maintain head pressure in DX Systems)
•Multi, for the chilled water input to the MultiCool coil or chilled water coil (Systems using chilled water only)
•None, for
Cndsr Vlv. The condenser fluid valve controls the flow of coolant into the heat exchanger or to the Economizer coil in direct expansion. Set the condenser fluid valve as either a two- or
Coil Fluid. The coil fluid valve controls the flow of coolant to the MultiCool, Chilled Water, or Economizer coil. Set the coil fluid valve as either a two- or
Actuator Types
Path: Main > Setup > System # > System Config > Actuator Types
Cndsr Vlv. Set the type of condenser valve actuator as Floating or None. The condenser valve is not present in
•Floating Control maintains the position of the valve when the power is off.
•None indicates that no condenser valve is installed.
Coil Fluid. Set the Coil Fluid valve actuator to Floating, Spr Anlg, or None.
•Floating Control maintains the position of the valve when the power is off.
•Spring (Return) Analog closes the valve when the power is off.
•None indicates that the Module does not have a MultiCool, Chilled Water, or Economizer coil.
