Configuring the Sensor kits
The Aurora Advanced Control allows Refrigeration, Energy,
and Performance Monitoring sensor kits. These kits can be
factory or field installed. The following description is for
field activation of a factory installation of the sensor kits.
Energy Monitoring
(Standard Sensor Kit Variable Speed Models)
The Energy Monitoring Kit includes two current transducers
(fan and electric heat) added to the existing two
compressor sensors so that the complete power usage of
the heat pump can be measured. The AID Tool provides
configuration detail for the type of blower motor and a line
voltage calibration procedure to improve the accuracy. This
information can be displayed on the AID Tool or selected
communicating thermostats. The TPCM32U04 will display
instantaneous energy use while the color touchscreen
TPCC32U01 will in addition display a 13 month history
in graph form. Ensure the Energy Kit has been enabled
by accessing the ‘Sensor Kit Setup’ in the AID Tool and
complete the following:
a. Select ‘Blower Energy’ – PSC or ECM/5-Speed ECM
b. Activate ‘Energy Option’ to activate the sensors on
for compressor (2), blower and aux heat current sensor.
c. Select ‘Pump’ option of FC1, FC2, VS Pump, VS +
26-99, or open loop. This selects the pump watts
used in the calculation. Pump watts are not
measured but estimated.
d. Line Voltage Calibration – Voltmeter required to
calibrate line voltage during heating or cooling.
i. Turn on Unit in Heating or Cooling .
ii. Use multimeter at L1 and L2 to measure
line voltage
iii. In the Sensor Kit Setup screen adjust the
‘Base Voltage’ to the nearest value to that
is measured
iv. Then use the ‘Fine Adjust’ to select the
exact voltage being measured at L1 and L2.
v. Exit ‘Sensor Setup’ Screen
e. Energy monitoring can be read on any of the
following components:
i. AID Tool – instantaneous information only
ii. TPCM32U04 Communicating
Thermostat (B/W) - instantaneous
information only
iii. TPCC32U01 Color Touchscreen
Thermostat – Both Instantaneously and
historical (13 months)
iv. WaterFurnace Web Portal via AWL
device hooked to Aurora (future release)
Refrigerant Monitoring
(Standard on Variable Speed Models)
The Refrigerant Monitoring Kit includes two pressure
transducers, and three temperature sensors, heating liquid
Unit Startup cont.
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 will
only be displayed on the AID Tool. Ensure the Refrigerant
Monitoring has been setup by accessing the ‘Sensor Kit
Setup’ in the AID Tool and complete the following:
Once sensors are installed for discharge pressure, suction
pressure, suction, liquid line cooling, liquid line heating, and
leaving air temperature no further setup is required.
a. Turn on unit in Heating or Cooling.
b. Use the AID Tool to view the refrigerant
performance in the ‘Refrigerant Monitor’ screen.
c. Refrigerant monitoring can be read on any of the
following components:
i. AID Tool – instantaneous information only
ii. WF Web Portal via AWL device hooked
to Aurora (future release)
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 AID Tool for selection of water or
antifreeze. Ensure the Performance Kit has been enabled
by accessing the ‘Sensor Kit Setup’ in the AID Tool and
complete the following:
a. Select ‘Brine’ – and then choose Water or
Antifreeze for the proper factor
b. Activate ‘Flowmeter’ to activate the flow sensor
select the appropriate 19.1mm, 25.4mm, or none
(25.4mm is standard on variable speed units).
c. Exit ‘Sensor Kit Setup’ screen.
d. Turn on unit in Heating or Cooling.
e. Use the AID Tool to view the performance in the
‘Performance Monitor’ screen.
f. Performance monitoring can be read on any of the
following components:
i. AID Tool – instantaneous information only
ii. WaterFurnace Web Portal via AWL
device hooked to Aurora (future release)
Startup Steps
NOTE: Complete the Equipment Startup/Commissioning
Check Sheet during this procedure. Refer to thermostat
operating instructions and complete the startup procedure.
Verify that the compressor shipping bolt has been removed.
1. Initiate a control signal to energize the blower motor.
Check blower operation through the AID Tool.
2. Initiate a control signal to place the unit in the
cooling mode. Cooling setpoint must be set below
room temperature.
3. First stage cooling will energize after a time delay.
