Purge Opening Size
The ridge vent can be used as a purge opening for purge fans. This menu item appears only if you have entered purge
settings in the Purge Settings menu. Input zero to disable the ridge vent during the purge function. The purge opening
size must be large enough to allow at least three seconds of movement.
RIDGE VENT GROUP #1 SETTING Z1-S01
Purge Opening Size (Inches): 4”
Interlock Curtain Groups
Ridge Vent Settings - continued
If you have set the Ridge to Curtains Interlock (refer to the Temperature Control Settings section) you can specify the
curtain groups here. Interlocking ridge vents to curtains enhances air quality in a building while maintaining good
temperature control. When ridge vents are interlocked, their open and close settings are ignored. The interlocked
ridge vent attempts to open the same number of inches as the curtain with the largest opening size. For example,
a curtain has a maximum opening size of 48 inches, and the ridge vent’s maximum opening size is 10 inches. As the
curtain opens, the ridge vent will also open the same amount as the curtain. When the curtain is open 10 inches, the
ridge vent will be fully open at 10 inches.
RIDGE VENT GROUP #1 SETTING Z1-S01
Interlock Curtain Grps: 1, 2, 3, 0, 0, 0
Input up to six curtain groups.
The Ridge Vents readjust themselves automatically with the controller when they open or close completely. When
the device is within 1”, or within three seconds of travel time, of fully open or closed, the channel is left on, allowing
the limit switch of the device to stop the moving of the device. This allows both the Ridge Vent and controller to
synchronize their positions.
However, you can have the device perform this re-synchronization manually once a day if needed. Set “Perform
Re-Sync at” to the time of day to perform the re-synchronization. If the device is less than 50% open at the specified
time, the controller will turn on the Close relay for the full amount of the Close Travel time of the device. If the device
is more than 50% open, the Open relay will turn on for the full Open Travel time. This will make sure the device’s
actual opening size matches the controller’s calculated opening size. Set the value to 0:00 to disable this feature. Set
it to 24:00 to have it run at midnight.
Perform Re-Sync
RIDGE VENT GROUP #1 SETTING Z1-S01
Perform Re-Sync at : 0:00
• If the device is moving when Re-sync is supposed to happen, the Re-sync operation will wait
until the device has stopped moving before it will turn the relay on for the full travel time.
• The Re-sync should be done at a time of day that will have the least effect on the environment
of the barn, such as early morning when it is less likely a lot of fans will be running.
• If the device seems to be out of sync often, check to make sure the manual winch has been
properly adjusted and the travel times of the device are accurate. Also check to make sure the
device settings allow the device to fully close or open at some point.
