ASM No. ASM08017
WSHP-454
The WSHP-454 Module monitors the compressors on an AAON® Water Source Heat Pump unit and can disable the compressors based on low Suction Pressure, 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-454 Module’s water circuit configuration can be either single or dual. There are nine glycol configurations for the WSHP-454 Module—0%-40% in increments of 5%. The glycol will automatically default to 0%.
The WSHP-454 Module can be used stand-alone. The WSHP-454 Module requires a 24 VAC power connection with an appropriate VA rating.
