Figure 36: RNE 120 - 140 Ton Unit Four Compressor WSHP Module Wiring
Water Source Heat Pump Module
RNE Units with DX Cooling will have either a Half VFD/Half Fixed
compressor confi guration or a Full VFD compressor confi guration. The
RNE 120 - 140 Ton units have four compressors and will have either
two VFD and two Fixed Compressors or will have four VFD Compres-
sors. The operation of these compressors is described in the Sequence
of Operation section of this manual.
For Water Source Heat Pump (WSHP) units, the outputs to the compres-
sors will always be wired from the Water Source Heat Pump Modules.
For RNE 120 - 140 Ton units, two WSHP-X2 Modules will always be
used. Each compressor will need to have a relay confi gured and wired
from these modules, and the VFD outputs will be wired from these
modules. The Suction Pressure Transducer for each compressor and the
Proof of Flow switch for each water circuit will also be wired into these
modules. See Figure 36 below and on page 45 for the wiring diagram.
On units confi gured for Half VFD/Half Fixed operation, the two VFD
Compressors will be driven from AOUT #1 & 3 on the 1st WSHP-X2
Module, although the individual compressor relays will be enabled
separately as needed. On units confi gured for Full VFD operation,
the 1st two VFD Compressors will be driven from AOUT #1 & #2 on
the 1st WSHP-X2 Module and the 2nd two VFD Compressors will be
driven from AOUT #1 & #3 on the 2nd WSHP-X2 Module. All four
compressor relays will be enabled separately as needed.
