ENVISION 2 COMPACT - 50 HZ INSTALLATION MANUAL
1. Energy Monitoring (Standard Sensor Kit on
‘Advanced’ models) - The Energy Monitoring Kit
includes two current transducers (blower and electric
heat) added to the existing two compressor sensors so
that the complete power usage of the heat pump can
be measured. The BACview Tool provides configuration
detail for the type of blower motor and a line voltage
calibration procedure to improve the accuracy. This
real time power usage information can be displayed on
the AID Tool and is available thru network points when
using BACnet or N2 Open.
• Compressor Current 1
• Compressor Current 2
• Fan Current
• Aux Heat Current
• Pump Selection
• Voltage
• Compressor Watts
• Fan Watts
• Aux Heat Watts
• Pump Watts (VS Only)
2. Refrigerant Monitoring (optional sensor kit) - The
optional Refrigerant Monitoring Kit includes two
pressure transducers, and three temperature sensors,
heating liquid line, suction temperature and existing
cooling liquid line (FP1). These sensors allow the
measurement of discharge and suction pressures,
suction and liquid line temperatures as well as
superheat and subcooling. This information can be
displayed on the BACview Tool, or the network when
using BACnet and N2.
• Htg Liquid Line
• Clg Liquid Line
• Discharge pressure
• Suction Pressure
• Discharge Saturated Temp
• Suction Saturated Temperature
• Superheat
• SubCooling
3. Performance Monitoring (optional sensor kit) - The
optional Performance Monitoring Kit includes: three
temperature sensors, entering and leaving water,
leaving air temperature and a water flow rate sensor.
With this kit, heat of extraction and rejection will
be calculated. This requires configuration using the
BACview Tool for selection of water or antifreeze.
• Leaving Air Temperature (supply)
• Alt Leaving Air Temperature (Supply)
• Entering Water Temperature
• Leaving Water Temperature
• Water Flow Meter
• Entering Air Temperature (from zone sensor)
• Brine Selection (water/antifreeze)
• Heat of Extraction/Rejection
