UNITS
Outside Unit Selection – Chooses outdoor unit type:
!
• Non-communicating – Allows you to manually enter settings for your
outdoor unit. If "non-communicating" outdoor unit is selected, change
44% 44%
the type (AC or HP), number of stages (1 or 2) and size (Tons) to match
the Outdoor Unit information.
UNITS
• 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.
Heat Pump Locked Out Below – Selects the outside temperature below
which the Heat Pump will not operate and your system will rely exclusively on
the furnace or auxiliary heat source. This should be determined by evaluating
the regions Heat Pump Balance point. If a non-communicating outdoor unit
is paired with a Econet enabled furnace an OAT sensor (RXGY-J02) or the
Econet internet sensor option must be used to lock out the heat pump when
only furnace operation is desired.
Note: A difference of two degrees will be enforced between the furnace and heat pump. Lockout
temperatures will be based off the outdoor temperature sensor connected to the outdoor unit and
NOT off the temperature provided under weather. In some instances internet connections may be
intermittent and an OAT sensor would be the most valid option.
