as I tried to do it in the demo room "speed controller behaviour" i'd like to do the following control (simplified):

- under a co2 level, the speed control of fans are set @10 for exhaust and 5% for intake. fixed values

- otherwise the fan toolbox control the fans speed between 50% and 100% depending on temp and humidity as the fan toolbox allows it.

----------

my goal is to have the complex following sequence (most of it is designed except this problem of fan speed)

- under a co2 level begin to fill up with co2

- when co2 reached the value or latest after 2min switch co2 off for security reason

- during the 2 last steps, and during 15min more the fans must work at 10%/5% (exhaust/intake). fixed values

- after these 17min, the fan toolbox must control the fans speed with parameters from inside toolbox during 43min max.

- then back to the first step.

i tried several idea with tools given for e.g. the speed compare. but the I/O input of the speed control toolbox act as 10/5% when input on and as 0/0% when input is off. so no way to do it like that.

when speed compare is set to lower. the fans speed is 10/5 or 0/0 but never take the fan control parameters

when speed compare is set to higher, the fans speed is always control by the fan toolbox and never at forced 10/5%...
