MPO-IQ VS Ultra

Member Posts: 1
I'm updating my boiler and considering the MPO-IQ and the Ultra by Weil-McClain. I'd like to set it up with outdoor reset as well. I see the MPO-IQ offers plug and play cards, but I don't see an automatic differential feature. The Advanced Features Module from Weil-McClain does offer it. Is it important to have the auto differential? I'm an electrician, not a plumber. Looking for suggestions...... Thanks Dan
