Inlet reset mode —
Select the desired reset
mode:
“Op/Cl”
to reset the actuator toward
its nearest position; select
“Close”
to reset the
actuator toward its closed position only or
select
“Off”
to disable the automatic reset.
Inlet reset now? —
Select
“Yes”
to reset the
actuator’s position now.
Day time —
Set the time at which resets are
performed.
Period —
Enter the frequency of inlet re-
sets. A reset can be performed once every
1-7 days.
Reset delay —
During a reset, the controller
opens or closes the inlet during this delay, or
up until a limit switch is reached. The reset
delay should be set to the same time value or
higher than the total opening time (as defined
in section 6.5.2).
Do Not Reset Inlets if Out.T° is Below —
To
prevent inlets from closing against ice, the
controller can stop all inlet resets when it is
too cold outside. Set the outside temperature
below which inlet resets are forbidden (this
includes manual resets). *
This parameter is ac-
cessible if an outside temperature sensor is enabled
(see section 4.7.1).
6.5.4. Inlet Calibration
[For potentiometer-based inlets only]
If inlet 1 uses a potentiometer, the actuator of
the inlet must be calibrated. This calibration
tells the controller what are the minimum and
maximum positions of the actuator:
Minimum calibrated position = opening of 0%
Max. calibrated position = opening of 100%

Inlet Calibration

Save minimum position? —
2.
To calibrate
the minimum position, use the
“Close”
switch
to close the inlet to its minimum position.
Once the inlet is closed, set the manual con-
trol switch to
“Off”
to stop the actuator.
Now that the actuator is closed, answer
“Yes”
to the “Save minimum position?” question on
screen. Once the
“Yes”
answer is posted, the
controller switches the answer back to
“No”
;
the minimum position is now saved.
Save maximum posi-

tion? —
To calibrate the
maximum position, use
the
“Open”
manual control
switch to fully open the inlet. Once the maxi-
mum inlet opening is reached, set the manual
control switch to
“Off”
to stop the actuator.
Now that the actuator is opened, answer
“Yes”
to the “Save maximum position?” question on
screen. Once the
“Yes”
answer is posted, the
controller switches the answer back to
“No”
;
the maximum position is now saved.
Once the calibration is

completed, set the manual
control switch back to the
“Auto” position to enable
the automatic control of
the inlet.
For best results, make sure at least
12 inches (30 cm) separates the minimum
actuator’s position from its maximum
position.
6.6. 0-10V Air Inlets
The controller has two 0-10V outputs that
can either be used to control heat lamps, heat
mats, inlets or fans. To operate these outputs,
the controller refers to the average tempera-
ture reading of their assigned temperature
probes (see sec. 4.7.3). This section shows
how a 0-10V inlet output works.
A 0-10V air inlet works exactly the same as a
potentiometer-based air inlet except that this
kind of inlet does not need to be calibrated.
0-10V Mode: Automatic / Manual: You can
manually control the opening of a 0-10V
output by using the manual control mode.
While this mode is used, the controller stops
controlling the output and lets you choose
the inlet opening.
