Ventilation Inlets
The Static Pressure setting sets the parameters necessary to operate the vents.
(1) Vent Anticipation -
When vent
anticipation is turned ON, the vents will
start opening before a negative
ventilation stage turns on and continue to
open until the vent opening necessary for
the desired target pressure is achieved.
(2) Learn Times –
When learn times “Yes” is
selected, the controller will automatically
adjust the time (seconds) before and after
the fans turn ON depending on the static
pressure. NOTE: This feature is disabled
in Optimum Mode.
(3) Time before fan starts –
The number of seconds before a negative ventilation stage turns ON that the vents
will start opening.
(4) Time after fan starts –
The number of seconds after a negative ventilation stage turns ON that the vents will
continue to open allowing the fans to increase to full speed.
(5) Reaction Delay –
The amount of time delay before the vent machine operates.
(6) Pressure Differential -
Number from target to start opening and closing vents.
Example: With Target 0.07 and Differential 0.02, the vents open when the pressure is above 0.08; The
vents will close when the pressure is below 0.06.
(7) Attic Inlets Installed –
Select Yes or No; If Attic Inlets are installed, select Yes. Refer to
Application
Note # 4809-0011
for complete application details regarding the Inlet Operation with Attic Vents.
(8) Pressure Ramping –
Select On or Off to enable or disable pressure ramping.
(9 & 10) Target Press. @ High Temp -
The target pressure when the outside temperature is at the high
temperature limit. Set both pressure and temperature limit.
(11 & 12) Target Press. @ Low Temp -
The target pressure when the outside temperature is at the low
temperature limit. Set both pressure & temperature limit.
(13 & 14) Attic Pressure –
When the Attic Inlets Installed = “Yes”, the target pressure will be the selected
pressure when the outside temperature is at the selected temperature. Set both pressure & temperature.
The Attic Inlets become active when either the Outside Temperature is at or below the selected Attic
Temperature OR any Heat Stage is activated. The Attic Inlets will remain active until the averaged house
temperature reach the selected Tunnel Off-Point Temperature. After the Tunnel Off-Point Temperature is
reached, the Attic Inlets will be disabled and remain disabled until any Heat Stage is activated.
