The Aurora ‘Base’ Control System cont.
Home Automation 1 and 2 Inputs
The Home automation inputs are simple closed contact
inputs that will trigger an AID Tool and thermostat alert
for the homeowner. These would require optional sensors
and or equipment for connection to the AXB board. With
two inputs two different sensors can be selected. The
selected text will then be displayed on the AID Tool and
communicating thermostats. These events will NOT alter
functionality or operation of the heat pump/accessories
and is for homeowner/service notification only.
Home Automation 1 - E23 HA1
With a closed dry contact signal, this input will cause an
alarm and Alert Code 23 to indicate on the stat or flash
on ABC. The AID Tool will allow configuration of this input
between the following selections:
• No Action
• Home Automation Fault [no lockout info only]
- Output from home automation system
• Security Alarm [no lockout info only]
- Output from home security
• Sump Alarm Fault [no lockout info only]
- Switch output from sump sensor
• Smoke/CO Alarm Fault [no lockout info only]
- Switch output from Smoke/CO sensor
• Dirty Filter Alarm [no lockout info only]
- Output from dirty filter sensor
Home Automation 2 – E24 HA2
With a closed dry contact signal, this input will cause an
alarm and Alert Code 24 to indicate on the stat or flash
on ABC. The AID Tool will allow configuration of this input
between the following selections:
• No Action
• Home Automation Fault [no lockout info only]
- Output from home automation system
• Security Alarm [no lockout info only]
- Output from home security
• Sump Alarm Fault [no lockout info only]
- Switch output from sump sensor
• Smoke/CO Alarm Fault [no lockout info only]
- Switch output from Smoke/CO sensor
• Dirty Filter Alarm [no lockout info only]
- Output from dirty filter sensor
Monitoring Sensor Kits
Energy monitoring
(Standard Sensor Kit)
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 the accuracy,
and a power adjustment setting that allows the compressor
power to be adjusted to match the units line voltage using
the provided tables. This information can be dispayed on
the AID Tool.
Performance and Refrigeration Monitoring (optional
sensor kit)
The optional Performance and Refrigeration Monitoring
Kits includes a pressure sensor, temperature sensors, and
a source side water flow rate sensor. The temperature
sensors monitor entering and leaving source, leaving load
water, heating liquid line and existing cooling liquid line
(FP1). The pressure sensor monitors the system's discharge
pressure. With this kit, heat of extraction and rejection will
be calculated. This requires configuration using the AID
Tool for selection of water or antifreeze. These sensors
also allow for the subcooling to be displayed on the AID
Tool. NOTE: Superheat displayed on the AID Tool is not
true superheat, it is the superheat of the vapor injection
circuit.
