Ac/Hp Settings - EcoNet RETST700SYS Guide D'utilisation

How do I connect a ventilator (HRV or ERV) to an EcoNet HVAC system?
One must use the ventilator's wall control in the traditional manner, except only wire the ventilator control to
the G terminal of the furnace (do not wire to the Y or W terminals). In the EcoNet furnace setup menu, change
the G Input Fan Control to a fan speed that is desirable to run with the ventilator. The EcoNet system monitors
the furnace G terminal, and will turn on the fan when requested by the G terminal signal (when it is not heating
or cooling).

Outside Unit Selection – Chooses outdoor unit type:
(locked)
• Non-communicating – Allows you to manually enter settings for your outdoor
unit. If "non-communicating" outdoor unit is selected, change
the type (AC or HP), number of stages (1 or 2) and size (Tons) to match the
Outdoor Unit information.
• EcoNet (locked) – Displays "EcoNet" if a communicating EcoNet Enabled
outdoor unit is discovered. The selection cannot be changed (locked).
• None – Lets the system know that there is no outdoor unit present.
Note: Outside Unit Selection is only applicable for furnace installations.
Var-Speed RPM Clamp – Allows reduction of the maximum compressor
speed. Can be used to reduce outdoor unit operating noise or indoor blower
airflow. This will also reduce the operating capacity.
Cool/Heat Airflow Adjust – Controls airflow adjustment in cooling and heat
pump heating, None (default), High (+10%), Low (-10%).
Utility Input Enabled? – If the system is using a "load shedding" device
provided by the utility company set to 'Yes'. The device must be connected
to terminal U2 & U on the VSODU. Once the dry contacts are connected
(non-powered) between U2 and U, change the setting to 'Yes'. When set to
'Yes' the system will not start the condenser when the connection from U2 to
U is open.
Heat Source – Allows selection of using just the furnace, or heat pump, as the
sole heat source in a dual-fuel installation. If "Both" is selected, the system will
stage up and down normally using the heat pump for initial heat stages, and
then the furnace as auxiliary heat.
Furnace Locked Out Above – Select the outside temperature above which
the furnace or supplemental electric heat will not run when matched with
a heat pump. The default is disabled and the temperature can be adjusted
between 0-55°F.
