Don't use a WaterUse:Equipment for this (this is something to model (typically hot) water usage at a faucet, all water used is replaced by mains water), but use a LoadProfile:Plant instead.
As far as on/off chillers, there aren't any specific objects to do this, in particular for "modular" type chillers that have several compressors. You could however use a Chiller:Electric:EIR and force the Minimum Part Load Ratio to something close to 1 to force your chiller to operate at rated capacity (haven't tested myself).
If your chiller is of modular type, say with 3 identical compressors, you'd model three identical chillers corresponding to each compressor.

myself). Make sure you set the Minimum Unloading Ratio to the same value as the Min PLR.
