Description Default Range PW Comments
Dual to Single Target -30 -5 to -100 T
Hysteresis for staging compressors up or down based on the efciency curves
Single to Dual Target 30 5 to 100 T
Dual to Single Factor 1.0 0.7 to 1.3 T Scaling factor when transitioning from dual to single compressor operation
Single to Dual Factor 1.0 0.7 to 1.3 T Scaling factor when transitioning from single to dual compressor operation
Stage Transition Target 1.0 .8 to 1.2 T Scaling factor for transitioning compressors based on efciency curves
Nameplate RLA
(VFD Load Side)
Factory set Model dependent T
Sets the Rated Load Amps (RLA) per compressor phase as given on the chiller
nameplate - Load Side Phase Data.
Maximum Amps 100% 70 to 100% O Inhibits capacity increase above %RLA. Unloading forced at 5% above value.
Demand Limit Enable OFF ON, OFF O
ON: Limits % RLA to a value set by the Demand Limit analog input,
where: 4 mA = 100% RLA
20 mA = Minimum Demand Limit Setpoint
OFF: The Demand Limit input is ignored.
Harmonic Filter Amp Rating Factory set Model dependent T Based on model of harmonic lter
CAUTION
Chiller Nameplate RLA MUST match chiller dataplate per compressor.
