o Tunnel Exit – Out T Diff from Tunnel: This parameter sets amount below the tunnel entry
temperature at which to exit tunnel ventilation. Tunnel temperatures are determined by the
sensors specified in Temperature Definition. Entry and exit is also controlled by these
sensors. The controller can not exit tunnel until the tunnel temperature is this much less
than the tunnel entry temperature. It must be a positive number. Default: 2.0
o Tunnel Exit Delay (min): Delay time after satisfying tunnel exit conditions. Default: 5
(minutes)
o Inc Delay Time: This is the standard minimum delay before increasing ventilation levels.
Default: 120 (sec)
o Decrease Level Delay Time: This is the standard minimum delay before decreasing
ventilation levels.
o First Tunnel Level: Switching into and out of tunnel ventilation is a major change in
ventilation. For tunnel ventilation, enter the first tunnel level here. If set on 0 there is no
tunnel level. Default: 0
The following table is an example of a proper ventilation setting. Note that tunnel is not noticeable on the
current table and is set according to the system parameter- 1
