AFFINITY SINGLE STAGE HYDRONIC INSTALLATION MANUAL
Unit Startup
Before Powering Unit, Check the Following:
NOTE: Remove and discard the compressor hold down
shipping bolt located at the front of the compressor
mounting bracket.
• High voltage wiring is correct and matches the
nameplate.
• Fuses, breakers and wire size are correct.
• Piping is completed and water system has been cleaned
and flushed.
• Air is purged from the closed loop system.
• Isolation valves are open and loop water control valves or
loop pumps are wired.
• Service/access panels are in place.
Powering The Controls
Initial Configuration of the Unit
Before operating the unit, apply power and complete
the following Aurora Startup procedure for the controls
configuration. An AID Tool is recommended for setup,
configuration and troubleshooting, especially with an
Aurora 'Advanced' Control. AID Tool version 2.05 or
greater is preferred.
1. Configure Aurora Screen
a. In advanced controls - Confirm AXB is added
and communicating.
b. If HydroStat is installed, add 'TST' and ensure
communication is present.
2. Aurora Setup Screen
a. AXB Setup
i. DHW Enable – Ensure air is purged from
HW system before enabling
ii. DHW Setpoint – 130 °F is the default
but can be changed from 100 to 140 °F
b. Sensor Kit Setup
i. Brine Selection – for HE/HR
capacity calculation
ii. Flow Meter – activates the flow meter
iii. Activate energy option
Load pump and Aux heat current
sensor activation
iv. Line Voltage calibration – Voltmeter
required to calibrate line voltage during
heating or cooling. Refer to Line Voltage
Calibration in this manual for more details.
e. Smart Grid Setup – Select Action option for utility
received on-peak signal
f. Home Automation 1 & 2 Setup – Select type of
sensor for two home automation inputs.
Configuring the Sensor Kits
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 on most
'Advanced' models)
The Energy Monitoring Kit includes two current transducers
(load pump 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 a
line voltage calibration procedure to improve accuracy. This
information can be displayed on the AID Tool. Ensure the
Energy Kit has been enabled by accessing the 'Sensor Kit
Setup" in the AID Tool and complete the following:
a. Activate 'Energy Option' to activate the sensors
for compressor (2), load pump and aux heat current.
b. Select 'Pump' option of FC1, FC2, or open loop.
Select 'Open Loop' if this heat pump is linked to a
flow center through another heat pump.
This selects the pump watts used in the calculation.
Source pump watts are not measured but
estimated.
c. Line Voltage Calibration – Voltmeter required to
calibrate line voltage during heating or cooling.
Refer to Line Voltage Calibration in this manual for
more details.
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. Power Adjustment: Refer to the Single Speed
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.
