iii. In the Sensor Kit Setup screen adjust the

‘Base Voltage’ to the nearest value to that

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.

TPCM32U03*/04*

Communicating

Thermostat (B/W) - instantaneous

information

only

iii. TPCC32U01* Color Touchscreen

Thermostat – Both Instantaneously and

historical (13 months)

iv. Web Portal via AWL

device connected to Aurora (if available)

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 (if available)

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. (if available)

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
