COMPACT 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.

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.

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.
