Wiring
IMPORTANT: The EcoNet™ control system requires
continuous 18 AWG thermostat wire. Do not use
phone cord to connect indoor and outdoor units. This
will damage the controls.
The EcoNet™ control system requires four (4) control
wires for unit operation:
• R 24 VAC
• C 24 VAC common
• Data wire E1 Communications
• Data wire E2 Communications
The EcoNet™ enabled air handler or furnace is
equipped with a 24-volt, 40 or 50 VA transformer for
proper system operation. See Figure 23 below for low
voltage wiring connections.
Figure 23: Low Voltage EcoNet
TM
Wiring
These wires need to be connected to each device
(Control Center, indoor air handler or furnace, and
outdoor unit).
Once all devices are connected, apply the line
voltage to the indoor and outdoor units.
When all devices are powered, the EcoNet™ Control
Center should detect the indoor and outdoor units
within 45 seconds.
Once the system is powered and all components are
communicating with each other, the airflow settings
will be automatically configured in the air-handler or
furnace.
All adjustments for indoor airflow are made at the
EcoNet™ Control Center from this point. Items
that can be changed are airflow trim adjustment,
on-demand dehumidification, cooling and heating
airflow and electric heat airflow. The Control Center
also has a wide range of fault and history information.
To access any of the control center menus press
the settings, status, or service icons at the bottom of
the touch screen. Refer to the air handler or furnace
installation manual and the EcoNet™ Control Center
installation manual for further details on setting up the
system and available adjustment options.
4.9.4 Conventional 24VAC
Thermostat Control Wiring
Connections
The (-)A18AZ/(-)P18AZ series of heat pumps allow
the installer to use conventional 24 VAC control
wiring and a conventional thermostat for limited unit
operation. The system will operate as a single stage
system at nominal capacity.
IMPORTANT: The preferred method of unit
installation and operation is by the EcoNet™
Communicating System which allows access to the
fault history of the system. This diagnostic information
is not available at the thermostat when the (-)A18AZ/
(-)P18AZ unit is using a conventional thermostat.
Thermostat control wiring requires a minimum of five
(5) wires for proper unit operation:
R – 24 VAC
C – 24 VAC common
Y1 – Nominal capacity operation
B – Heat pump operation
W – Supplemental Heat During Defrost Cycle
The following figures show the typical control wiring
diagrams with (-)A18AZ/(-)P18AZ heat pumps using a
conventional 24VAC thermostat. Adjust indoor airflow
using the Bluetooth Contractor's App (Dipswitches
are not available).
