WSHP-X Module

Overview

The OE334-26-WSHPX-A Water Source Heat Pump X (WSHP-X)

Module monitors the compressors on an AAON

Water Source Heat

Pump unit and can disable the compressors based on low Suction Pres-

sure, Leaving Water Temperature, and Water Proof of Flow inputs. It

also utilizes a Delay Timer to prevent the compressors from turning on

at the same time.

The WSHP-X Module’s water circuit conﬁ guration can be either single

or dual. There are eight R410-A glycol conﬁ gurations for the WSHP-X

Module—0%-40% in increments of 5%. There are two refrigerant selec-

tions—R410-A refrigerant and R-22 refrigerant. If R-22 refrigerant is

selected, the glycol will automatically default to 0%.

The WSHP-X Module can be used stand-alone. It can also be connected

to the VCM-X WSHP Controller or the SA Controller using the E-BUS

Distribution Module or the module can be directly connected to the

VCM-X WSHP E-BUS Controller or SA E-BUS Controller, allowing

the Module to receive setpoints from the Controllers. See chart on page

2 for part numbers. Please note: The SA series of controllers only work

with the R410-A dual water circuit conﬁ gurations.

The WSHP-X Module requires a 24 VAC power connection with an

appropriate VA rating.

NOTE: The WSHP-X Module is factory set for R410-A and 0%

glycol.

Features

The WSHP-X Module provides the following:

 Can be operated stand-alone or connected to a

VCM-X WSHP Controller or SA Controller using

the E-BUS

Distribution Module to E-BUS interface

 Can be directly connected to a VCM-X WSHP E-BUS

Controller or SA E-BUS Controller

 Capable of controlling digital compressors when

connected to a VCM-X WSHP Series Controller or

SA Series Controller

 Monitors suction pressure, leaving water

temperature, and water proof of ﬂ ow

 Provides Delay Timer to prevent compressors

from turning on at the same time

 Contains a 2x8 LCD character display and 4 buttons

that allow for status display, setpoint changes, and

conﬁ guration changes

NOTE: The WSHP-X Module contains no user-serviceable parts.

Contact qualiﬁ ed technical personnel if your Module is

not operating correctly.
