6.5.1.3 Resetting the Actuator's Position
The controller needs to reset the actuator's posi-
tion at regular intervals to make sure the vent door
(inlet) position is always accurate. This reset is per-
formed automatically according to one of these two
methods:
•
Reset the minimum position only
(Close mode)
Each time a reset is performed, the vent door
(inlet) totally closes. Once the actuator's po-
sition is reset, the vent door (inlet) returns
to its previous position. The "Close" pilot light
of the vent door (inlet) flashes while the ac-
tuator is closing.
•
Reset toward the nearest position
(Open/Close mode)
If the current inlet position is higher than
50% at the reset time, the controller fully
opens the vent door (inlet) to reset the
actuator's position; if the current vent door
(inlet) position is lower than 50%, the con-
troller closes the actuator to perform the
reset. This way, the vent door (inlet) never
closes when the room temperature already
asks for a wide opening. The "Open" or "Close"
pilot light of the vent door (inlet) output
flashes while the actuator opens or closes.
Make sure limit switches are
located at both ends of the
actuators when using this re-
set method.

The following parameters are
common to all programs and to all
timer-based vent doors (inlets).
Vent / Inlet reset mode
Select the desired reset mode: "Op/Cl" to
reset the actuator toward its nearest posi-
tion; select "Close" to reset the actuator
toward its closed position only or select
"Off" to disable the automatic reset.
Vent / Inlet reset now? Select "Yes" to re-
set the actuator's position now.
Day time: Set the time of day at which re-
sets are performed.
Period: Set the frequency of inlet resets. A
reset can be performed once every 1-7 days.
Reset delay
During a reset, the controller opens or closes
the actuator during the Reset Delay or up
until a limit switch is reached. The Reset De-
lay should be set to the same time value or
higher than the total opening time of the ac-
tuator (as defined in section 6.5.2).
