Define:
o
Ventilation Tuning: This parameter determines how aggressively the Trio
responds to differences between the measured temperature and the target
temperature.
CAUTION Munters recommends leaving this paramter at Normal.
o
Total Cycle Time: When the tunnel is working in cycle mode, the total
cycle is defined here.
o
Tunnel Exit 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, regardless of the inside temperature.
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.
