Figure 36, cont.: RNE 120 - 140 Ton Unit Four Compressor WSHP Module Wiring
The WSHP-X2 Module monitors conditions on the unit and can dis-
able compressors based on Low Suction Pressure, Low Leaving Water
Temperature, or a loss of Water Proof of Flow. It also utilizes a Delay
Timer to prevent the compressors from turning on at the same time.
The WSHP Modules connect together and then connect back to the RNE
Controller or the Two Condenser Head Pressure Modules with HSSC
cables. This allows setpoints, status values, and alarms to be communi-
cated between the RNE Controller and the WSHP Module. This module
requires a 24 VAC power connection with an appropriate VA rating.
NOTE: The Compressor Relays on the WSHP Module are used
rather than the relay outputs on the RNE Controller.
NOTE: For more information, see the WSHP-X2 Module Field
Technical Guide.
