Aurora ‘Advanced’ Control Features

The Aurora ‘Advanced’

Control system expands on

the capability of the Aurora

‘Base’ Control (ABC)

by adding the Aurora

Expansion Board (AXB).

All of the preceding

features of the Aurora

‘Base’ Control are included.

The following control

description is of the

additional features and

capability of the Aurora

advanced control.

It is highly recommended the

installing/servicing contractor obtain

an Aurora Interface and Diagnostic

Tool (AID) and specialized training

before attempting to install or service

an Aurora ‘Advanced’ control system.

The additional AXB features include the following:

AXB DIP Switch

DIP 1 - ID

: This is the AXB ModBus ID and should always

read On.

DIP 2 & 3 - Future Use

DIP 4 & 5 - Accessory Relay2

: A second, DIP configurable,

accessory relay is provided that can be cycled with the

compressor 1 or 2 , blower, or the Dehumidifier (DH)

input. This is to complement the Accessory 1 Relay on

the ABC board.

Advanced Hot Water Generator Control
(Domestic Hot Water Option)

In lieu of the ‘Base Hot Water Generator Control’, the

Advanced features an AID Tool selectable temperature limit

and microprocessor control of the process. This will maximize

hot water generation and prevent undesirable energy use. An

alert will occur when the hot water input temperature is at

or above setpoint (100°F - 140°F) for 30 continuous seconds

(130°F is the default setting). This alert will appear as an E15

on the AID Tool and the hot water pump de-energizes. Hot

water pump operations resume on the next compressor cycle

or after 15 minutes of continuous compressor operation during

the current thermostat demand cycle. Since compressor hot

gas temperature is dependent on loop temperature in cooling

mode, loop temperatures may be too low to allow proper

heating of water. The control will monitor water and refrigerant

temperatures to determine if conditions are satisfactory for

heating water. LED1 (red LED) will flash code 15 when the

DHW limit is reached and when conditions are not favorable

for water heating. Error code 15 will also be displayed on the

AID Tool in the fault screen. This flash code is a noncritical

alert and does not necessarily indicate a problem.

Compressor Monitoring

The AXB includes two current transducers to monitor the

compressor current and starting characteristics. Open

circuits or welded contactor faults will be detected. A fault

will produce an E10 code.

Loop Pump Linking

This input and output are provided so that two units can be

linked together with a common flow center. When either unit

has a call for loop pump, both unit’s loop pump relays and

variable speed pumps are energized. The flow center then can

simply be wired to either unit. The output from one unit should

be routed to the input of the other. If daisy chained up to 16

heat pumps can be wired and linked together in this fashion.

Advanced Communication Ports

Communication ports P6 and P8 will provide future

expansion via dedicated protocols. These are for future use.
