7.7 Tunnel Ventilation
The Tunnel Setup screen sets the parameters necessary to operate in the Tunnel mode.
(1) Target – Displays the target temperature
of the building.
(2) Tunnel Enabled – Select either
Yes or No to enable or
disable going into the Tunnel
mode.
(3) Sensors – The user is given the
choice as to what sensors will
be used to enter and exit
Tunnel Mode; select any or all
of the available sensors. To
use the outside sensor when
entering tunnel set the sensors
to display the word “outside”
by turning all the sensors off.
(4) Tunnel ‘On Sensors’ – Selectable for 1-8 sensors. Select the sensors used for entering Tunnel Mode.
(5) Tunnel ‘On Temperature’ – The temperature at which the controller will go into tunnel mode.
(6) Tunnel ‘Off Sensors’ – Selectable for 1-8 sensors. Select the sensors used for exiting Tunnel Mode.
(7) Tunnel ‘Off Temperature’ - The temperature at which the controller will go out of tunnel mode.
(8) Use Tunnel Target Pressure – Yes or No. This will allow a different Target Pressure to be used in the
Tunnel mode.
(9) Natural Unit #2 is Tunnel Inlet – Yes or No. This indicates that PowerTrak Number 2 of the Natural
Set is a Tunnel inlet and will open during Tunnel.
(10) Enable Low Pressure Alarm in Tunnel – Yes or No. Set to Yes if it is desired to use a low pressure
alarm while in the tunnel mode.
(11) Increase High Temperature Limit +##° in Tunnel –While in the tunnel mode the Evolution 3000
can adjust the High Temperature Limit. Enter the number of degrees that the limit is to be
increased while in the tunnel mode. This increase will only be used while in tunnel.
(12) Tunnel Timeout – This feature prevents the controller from flip-flopping in and out of tunnel and
also provides a means for the controller to retry tunnel ventilation after a tunnel error. The Tunnel
Timeout counter forces the controller to wait at least 30 minutes between tunnel initiation. For
example, if the controller is in tunnel and an error occurs, the controller will reload the tunnel
timeout, exit tunnel ventilation, and sound the alarm. After the tunnel timeout expires, the
controller will reset the tunnel error, turn off the alarm, and if the conditions allow, retry tunnel
ventilation. The tunnel timeout will be reset during a power-on reset or if the Tunnel Enable is
toggled from off to on. As long as “30:00” is displayed, tunnel ventilation is allowed. If it is in
process of counting, then it is not allowing tunnel ventilation at this time due to a previous error or
because it has recently made an attempt.
