Precision Ventilation - A Quick Look
R O TEM’s
Precision Ventilation works by giving the Platinum many finely spaced levels of
ventilation to choose from. This allows it to find the right ventilation for the conditions. A
typical change in ventilation from one level to the next in Precision Mode is 20%, compared
to as much 1,000% in Standard Mode (for example, when the Minimum Ventilation Timer
setting is 30 Seconds On, 270 Seconds Off).
Consider the following simplified Ventilation Levels example:

7 0 90 210 1 and 2
1½ Minutes out of 5, 20% more
than Level 6
… … … … … … Higher Levels
The Platinum is currently at Level 6, which in this example means two cycle or timer fans
run 1¼ minutes out of 5. If required, the Platinum will move to Level 5 or Level 7 to
maintain the Target Temperature.
Note the
Diff ºF
column, in this example, the Differential Temperature for each level is
Zero . This means that all these levels occur at the same temperature! In Precision Mode,
the Platinum finds that level of ventilation which precisely maintains the target temperature.
How does it do this? Very well, thank you. You will need to read deeper into this volume to
get the details!
Besides maintaining more accurate and precise temperatures, Precision Mode has other
benefits. A few examples:
1. Increased Reliability - it can ‘rotate’ minimum ventilation timer fans so that all of
your fans get a turn.
2. Save Fuel while Ventilating Better - it can automatically decrease ventilation as
fuel use increases, and increase ventilation whenever outside temperatures allow
economical use of free air. See the ‘Soft Min Vent’ section.
3. Recapture Free Heat - it has features to bring otherwise lost heat back to the birds
where it benefits them. See the ‘Stir Fans’ sections.
This volume describes the features and benefits of Precision Mode in the following pages.
