Define:
o
Tunnel Hysteresis: This is a differential. When the temperature reaches the tunnel
temperature minus this differential, ventilation goes down to Extra Ventilation (if enabled)
or Minimum Ventilation.
o
Outside Temp Exit Limit: This is a differential. When the outside temperature reaches the
tunnel temperature plus this differential, ventilation will remain in Tunnel Mode.
o
Tunnel Exit Delay (min.): When TRIO calculates that ventilation should exit Tunnel Mode,
there is a delay (of this amount of time) before actually exiting. This parameter prevents
TRIO from entering and exiting Tunnel Mode too rapidly.

OORS
In Tunnel Ventilation, TRIO enables control over the tunnel doors using control by level or control by
static pressure. Control of these doors is the same as control over inlets. Refer to these sections for details.
