EcoNetTM Control Installation Instructions
The EcoNetTM System consists of several intelligent, communicating components. Commands, operating conditions, and other data are passed continuously between components. All system components are controlled through the wall mounted EcoNet Control Center, which replaces the conventional thermostat and provides the homeowner with a single wall control for all features of the system.NOTE: Read the entire instruction manual before starting the installation.

- Air Handler Settings
- AC/HP Settings
Failure to read and follow all instructions carefully before installing or operating this control and system could cause personal injury and/or property damage.NOTE: All wiring must comply with national, local, and state codes. WARNING: Disconnect power to the outdoor and indoor units before beginning installation.
EcoNetTM Control Center Location
The EcoNet Control Center is the command center for the EcoNet System as well as the control for the heating and cooling equipment.It should be located where it is easily accessible and visible to the homeowner or end user. For accurate zone temperature and humidity measurement, the following guidelines should be followed:
- The EcoNet Control Center should be mounted:
- Approximately 5 feet (1.5 m) from the floor.
- Close to or in a frequently used room, preferably on an inside wall.
The EcoNet Control Center should NOT be mounted:
- Close to a window, on an outside wall, or next to a door leading to the outside.
- Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature-radiating objects which could cause a false reading.
- Close to or in direct airflow from supply registers or returns.
- In areas with poor air circulation, such as behind a door or in an alcove.
- On a section of wall with pipes or ductwork.
Ordinary thermostat wire is recommended. Use 18 AWG or larger for normal wiring applications.NOTE: Wiring only requires a fourwire, or in some cases, a three or two-wire connection; however, it is good practice to run thermostat cable having more than four wires in the event of a damaged or broken wire during installation.
The units should be wired in a “daisy chain” and not in a “star” configuration. To “daisy chain” the units on the network, each unit should have a set of wires coming into it and one set going out of it except the two communicating devices that are at the ends of the network. The devices on the ends should have only one set of wires to it. The order of the devices in the network is not specified except the EcoNet Control Center should be at one end of the network.
Wiring length should not exceed 125 feet between communicating controls. The maximum wire length from end to end is 500 feet. The EcoNet Control Center has a four-terminal connector labeled R, C, E1, E2.
Example of Control Center connection with HVAC unit. Please note this is an example only and the ordering network can change as long as it is daisy chained.
Example of Control Center connection with HVAC and Water Heater unit. Please note this is an example only and the ordering network can change as long as it is daisy chained.
Shielded Wire (Optional) If the thermostat wiring will be located near or in parallel with high voltage wiring, cable TV, Ethernet wiring, or radio frequency equipment, then shielded thermostat wire can be used to reduce or eliminate potential interference. The shield wire should be connected to the C terminal, or ground, at the indoor unit only. The shield wire from all of the thermostat runs should be attached together and only grounded at the indoor unit. The shield wire should NOT be connected to any terminal at the Control Center. Connecting the shield to ground at more than one location can cause current loops in the shield, reducing shield effectiveness.
Mounting EcoNet Control Center
A backplate is supplied (see Fig. 1). Attach backplate using only a small hole in the wall allowing a four wire connection to pass through. A large backplate trim ring is available as an accessory to help cover gaps with paint color or wallpaper.
WARNING: Mercury is a hazardous waste, if existing control contains any mercury, it MUST be disposed of properly. The EcoNet Control Center does not contain mercury.
|Turn off all power to equipment (i.e. furnace or air handler and outdoor unit).||Push any excess wire back into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.|
|If an existing thermostat or control is being replaced:
a. Remove existing control from wall.
b. Disconnect wires from existing control.
c. Discard or recycle old control.
|Attach EcoNet Control Center to the mounting plastic by lining up the holes on the back of the control with the plastic guides on the backplate and push on.|
|Route wires through hole in backplate plastic. Level backplate plastic against wall (for aesthetic value only – Control Center does not need to be level to operate properly) and mark wall through two mounting holes.||Perform installation of all other system equipment.|
|Secure backplate plastic to wall using screws and anchors provided.||Turn on power to equipment.|
|Match and connect thermostat wires to proper terminals on backplate. Note the wire color used for each terminal, as it is good practice to use the same wire color on identical termination points on the indoor and outdoor units.|
Use of Humidifier
It is recommended to not install a traditional humidistat in this communicating system. If a humidifier is installed, let the EcoNet Control Center control humidification. See furnace or air handler instructions for humidifier connection.
To adjust equipment settings, press the Settings icon and select Installer on the lower right side of the screen. Press Furnace or AC/HP to select the desired equipment to change. The Command Center automatically recognizes communicating products on the system.NOTE: If a non-communicating outdoor unit is attached, enter the Settings > Installer > AC/HP menu and edit the outdoor unit’s settings to match the attached equipment (Type, Stages, Size).
If an EcoNet outdoor unit is installed, it will be automatically recognized and used with the appropriate settings.
