Note: Don’t confuse Set Temperature in Standard Mode with Target Temperature in Precision Mode.
The Set Temperature is generally between heat and fan on/off temperatures. However, it can be
higher or lower since it is only a reference.
The Precision Mode Target Temperature is an actual goal the Platinum Plus tries to achieve. It is not
simply a reference temperature.
Standard mode works reliably, but is not optimum for the whole growth
cycle. Precision ventilation mode provides more optimum control under various
bird age and weather conditions, but, it takes greater effort and care to program.
Precision Ventilation Mode
The Precision Ventilation provides more optimal control for the entire
growth cycle. Instead of just one curve for target temperature, it provides two
additional curves, a separate one for heating and another for tunnel entry or
cooling.
This way you can increase the difference in set point of the heaters with
bird age, so they come on at relatively lower temperatures as the birds put on
feathers. You can reduce the difference for tunnel entry, so tunnel occurs at
relatively lower temperatures for 6-week birds than for 3-week birds. This
adjusts for the greater wind chill effect of tunnel air speed on small birds
compared to large birds.
