Hello

I have an application where i want to control humidity using s7 1214c dcdcdc under tia v17 

The humidifier is controled with on/off valve and the desuhumidification with on / off valve of the  cooling system.

I want to use a pid which has a one input and two outputs .

I tried the pid temp but it did not work .

Please could you have any guidence ?
