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. Power Adjustment: Refer to the Dual Capacity
Power Adjustment tables in the Aurora ‘Advanced’
Control section of the literature
i. On the Main Menu screen select Setup
ii. Once in the Setup menu select the Power
Adjustment Factor
iii. Power Adjustment - allows you to enter
the unit’s compressor power setting for
high and low speed operation.
Refer to the tables and use the voltage
that is closest to the unit’s line
voltage and set the power adjustment
accordingly.
f. Energy monitoring can be read on any of the
following components:
i. AID Tool – instantaneous information only
ii. TPCM32U03A/04A 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 connected to Aurora
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 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. Symphony Portal via AWL device
connected to Aurora
Unit Startup cont.
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 Energy 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 3/4 in. (026 models),
1 in. (038-072 models), or none.
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. Symphony Web Portal via AWL device
connected to Aurora.
Startup Steps
NOTE: Complete the Equipment Start-Up/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.
4. Be sure that the compressor and water control valve or
loop pump(s) are activated.
5. Verify that the water flow rate is correct by measuring the
pressure drop through the heat exchanger using the P/T
plugs and comparing to unit performance data in catalog.
6. Check the temperature of both the supply and discharge
water (see the Unit Operating Parameters tables).
7. Check for an air temperature drop of 15°F to 25°F across
the air coil, depending on the fan speed and entering water
temperature.
8. Decrease the cooling set point several degrees and verify
high-speed blower operation.
9. Adjust the cooling setpoint above the room temperature
and verify that the compressor and water valve or loop
pumps deactivate.
10. Initiate a control signal to place the unit in the
heating mode. Heating set point must be set above room
temperature.
11. First stage heating will energize after a time delay.
12. Check the temperature of both the supply and discharge
water (see the Unit Operating Parameters tables).
13. Check for an air temperature rise of 12°F to 35°F across the
air coil, depending on the fan speed and entering water
temperature.
