The Platinum Plus has a separate tunnel entry temperature curve, as we will see further
below. It is this tunnel entry temperature that determines when the Platinum Plus enters tunnel
ventilation. This is the reason there is no differential on the first tunnel level.
Several of the set parameters (press Help then choose the Set option) are important.
You should set both the first tunnel level and the maximum number of levels according to
your program. You should also set the tunnel exit temperature to a reasonable value in the
Help | Set parameters.
Precision Ventilation Example
The next table illustrates one possibility for a fairly typical broiler house. This
example uses two 36” sidewall fans and twelve 48” tunnel fans.
Levels 1 through 5 are for extremely cold weather with young birds and very clean
litter. The cycle timers are on a ten minute basis.
Levels 6 through 15 are for half house brooding under normal litter conditions. The
fan cycle time is five minutes. Note the rotation of the tunnel fans at level 15. A different fan
runs the timer cycle each time. In houses with no sidewall fans at all, you can use this
technique to spread the minimum ventilation work load on several or even all your tunnel
fans.
Levels 16 through 30 are for full house use, with level 25 being the first tunnel level.
Stepping a cycle fan helped this grower know the ventilation level visually from outside the
house.
Note the differential temperatures for the transitional ventilation region at levels 23
and 24. The differentials from levels 26 and up are relative to the tunnel temperature set in
Control | Temperature Curve. They account for the additional wind chill as more fans come
on in higher tunnel levels.
