Table 1. Home Screen and System Status Icons
Icon Screen Text Purpose
Emergency Heat
All heat pumps operating in northern climates below 35°F
(1.6°C) normally need a supplemental heating source.
Usually it is in the form of electric heating provided by the
indoor unit. Other sources could be gas, oil, or hot-water
back-up systems as well. The supplemental heat is also
referred to as “second-stage” or “back-up” heating, with
“rst-stage” being the heat pump only. Emergency heat
is when you use your supplemental heat (2nd stage) by
itself, without the use of your heat pump (1st stage heat).
Not available for non-heat pump systems.
Auxiliary Heat
Is only available with heat pump system. If outdoor
temperature is above the high balance point, only the
heat pump will operate - default 50°F (10°C) high. If
outdoor temperature is below the low balance point, only
auxiliary heating will operate - default 25°F (-4.0°C) low.
If outdoor temperature is in-between the high and low
balance point, both the heat pump and auxiliary heat
sources can operate.
Will start soon
A ve minute safety delay prevents the compressor from
operating too soon after shut-down to allow internal
pressures to equalize.
Ambient lockout
This indicates that either the outdoor temperature is above
or below the balance point temperature settings. The low
balance point setting prevents heat pump heating below
the set point and back up heat will be used. Typically the
default is 25°F (-4.0°C), but that setting can be adjusted
by your dealer. At 25°F (-4.0°C) or below for example,
only auxiliary heating (electric or gas) is used. If the high
balance point is set to 50°F ( 10°C ) for example, which
is also adjustable by your dealer, then auxiliary heat will
not be allowed. Only heat pump heating will be used.
Anytime the outdoor temperature is below or above the
balance point temperature settings, the ambient lockout
notice will appear on the home screen.

Troubleshooting Wi-Fi Connection
The following terminology is used in this troubleshooting section:
• Received Signal Strength Indication (RSSI). This is an indication of the
signal strength of the Wi-Fi router being received by the scanning device
(i.e., smart phone). Therefore, the higher the RSSI number (or less negative
in some devices), the stronger the signal.
• Wireless Bands 802.11a, g and n Supported. These are wireless
networking standards that extends bandwidth throughput up to 130mbps
using the 2.4GHz band.
• Internet Protocol Address (IP address). This is an address assigned by
your home router for each network device (e.g., computer, printer, thermostat).
Electromagnetic Interference Causing Poor Connectivity: Locate the
thermostat and router away from other devices that could possibility interfere
with wireless communications (especially those operating on 2.4GHz
frequency). Some examples of other devices that may interfere are:
• Microwave ovens
• Wireless cameras
• Portable phones and bases
• Baby monitors
• Wireless speakers
• Bluetooth devices
• Garage door openers
• Neighbor’s wireless devices
To eliminate a possible source of interference, temporally disable any devices
and see if Wi-Fi performance has improved.
Received Signal Strength Indication (RSSI)
The ideal signal strength range for the thermostat is -1 to 69 RSSI. The signal
strength can be viewed from the thermostat interface.
1. Press NETWORK SETTINGS. This screen shows a graphical view of
buttons representing OPEN and SECURE wireless networks, along with
button for adding a network.
2. Select the access point that has already been established and connected.
When selecting the info icon, a screen will appear which will display an
option to forget the network and IP address assigned to the thermostat
by your router, sub-net mask, router, DNS and RSSI. If the RSSI signal
strength is anywhere between -9 to -69, then the signal strength is
sufcient. If outside this range, then either relocate the router closer to the
thermostat, add a repeater, or move the Smart Hub. Adjusting antennas on
router and/or Smart Hub may resolve any connectivity issues.

Away Sync
Away Sync is a feature that can be enabled once you have created and
registered your account. Both Home Info and Account options must be
completed before this option can be enabled.
The Away Sync feature depends on:
• Comfort Sync A3 Thermostat App running on your mobile device (smart
phone or tablet) and being logged in to your account.
• Requires Wi-Fi and location settings to be enabled on your mobile device.
Android devices must also have the location mode set to “high accuracy.”
Consult your mobile device user guide for instructions.
NOTE: Starting with Android version 10, when allowing the mobile app access
to device location, you must select “Allow all the time” for the Away
Sync feature to work correctly.
Away Sync can also be enabled from your mobile device once you have
installed the Allied Comfort Sync A3 App and logged in. Go to the menu >
settings > away and turn ON Away Sync. To allow the mobile device you are
on to use this feature, turn ON participate. The away fence option will appear
and by default, the setting is two miles (3 km). The range for this setting is 2 to
6 miles (3.00 to 9.50 km).
Inner and Outer Away Fences
The inner away fence is set by the user anywhere between 2 to 6 miles (3.00 to
9.50 km) on the mobile app. This setting can be different for each participating
mobile device. When any of the participating mobile devices are located inside
of its inner away fence, the system will not be in Away Sync; the system will
use the temperature set points dened by the schedule or what was manually
set. Once the inner away fence is set, the outer fence for each participating
mobile device will be automatically calculated by the Away Sync algorithm.
Transition Set Points
When the closest participating mobile device is between the inner and outer
away fences, the thermostat will show the Away Sync indicator. The system will
use transition set points to heat or cool the home. The transition temperature
set points are automatically calculated by the Away Sync algorithm using a
combination of the home and away set points.
Away Set Points
Once all participating mobile devices have moved outside the transition range,
the thermostat will continue to show the Away Sync indicator, and the user-set
away set points will be used to control the system.
Example: Away set points are 65ºF (18.5ºC) for heating and 85ºF (29.5ºC) for
cooling. When the away fence is set to two miles for all participating mobile
devices, and the closest participating mobile device is within the 0-2 mile (0
to 3.22 km) range of the home, the system is considered home; the system
will use the set points from the schedule or what was manually set. If the
closest participating mobile device moves into the 2.1 to 8 miles (3.40 to 13.04
km) range, the system is considered in transition, and the system will start to
either increase or reduce the heating or cooling set point. Once all participating
mobile devices have moved beyond the 8.1 mile (9.50 km) range from the
house, the system sets the set points to the away set points (65ºF for heating
and 85ºF for cooling).
Multiple Devices
It is possible to have more than one mobile device participating in Away Sync
for this system. The away fence can be set to the same value or different
values for each mobile device. The thermostat will not show the Away Sync
indication until all devices have moved past their inner away fence, and the
system will not reach the user-set away set points until all devices have moved
past their outer fence.
NOTE: Away Sync will be canceled when the system is enrolled in energy
savings with a utility provider and a energy saving event is active.

congured by your installer. Either ERV or HRV could be congured as single
or two-stage if applicable.
Menu Selection
When selecting this menu option, selections will be either:
• Timed or ASHRAE (either Timed or ASHRAE is set by your installer during
setup of your thermostat).
• On (always)
• Off (always).
Factory default is ASHRAE. Your installer will need to change it to Timed if that
mode is desired.
You can also select “ventilate now” to start a ventilation function immediately.
Those menu options are 10, 20, 30, 40 and 50 minutes, 1 hour, 1-1/2 hours, 2
hours, 2-1/2 hours, 3 hours, 3-1/2 hours and 4 hours and custom. Custom will
allow to set a specic time to run too.
NOTE: On two-speed ventilators, when ventilate now is selected, the
ventilator will come on at high speed.
NOTE: Once ventilation is started, a notication appears on the right-side of
the home screen indicating a time when that specic cycle will end and
the option to cancel the demand.

acceptable indoor air quality in typical residences. It was developed and is
maintained by the American Society of Heating and Air-Conditioning Engineers
(ASHRAE). One of the standard three main components is Whole House
Ventilation which is exhausting stale indoor air and replacing it with fresh
outdoor air.
