Lo/Hi Stat. Pressure — Set the static pressure
level below/above which the tunnel inlet must
close/open. * This parameter is accessible if the
tunnel inlet operates according to static pressure
level (see section 4.4).
Wind Delay — When the pressure level
exceeds the high or low static pressure set
limit, the tunnel inlet waits for the end of the
“Wind Delay” before moving. The high or low
pressure condition must be maintained during
the whole delay for the tunnel inlet to start
moving. This way, the tunnel inlet does not
move if a wind draft causes fleeting changes
in the pressure level. Set the
“Wind Delay”
to
the desired value. *
Note that this parameter is
common to all pressure-based air inlets (sidewall,
attic and tunnel inlet).

To modify use
Set the following parameters: 2.
Pre-opening — Specify how much time is
required to pre-open the tunnel inlet at the
startup of tunnel ventilation (if no transition is
made) or at the startup of the transition from
lateral to tunnel ventilation. The controller will
pre-open the tunnel inlet before activating the
fans at the startup of the tunnel fan that is
labeled
“Start Tunnel”
or
“St.Tun,Clo side”
(refer
to section 6.5.3). *
This parameter is accessible if
the tunnel inlet operates according to static pressure
level (see section 4.4).
Pre-opening 2 — Specify how much time is
required to pre-open the tunnel inlet at the
startup of tunnel ventilation (when the transi-
tion from sidewall to tunnel ventilation is over).
The controller will pre-open the tunnel inlet
before activating the fans at the startup of the
tunnel fan that is labeled
“Close sidewall”
(refer
to section 6.5.3). If no transition is made, this
delay is simply added to the initial pre-opening
delay. *
* This parameter is accessible if the tun-
nel inlet operates according to static pressure level
(see section 4.4).

6.6. Cooling Outputs
The controller has 6 cooling outputs that can
be used to activate various types of cooling
devices. A cooling output starts operating in
timer mode when the average temperature
reaches its
“ON Temperature” . The “ON Time”
portion of the timer then increases as the tem-
perature rises, up until it reaches the
“Cycle
Time” (i.e., the cooling output is always on).
This happens when the average temperature
reaches the
“Max Run T°” parameter value. The
graph below sums up this situation.
