Staefa Control Sys Service & Repair Forum
We are replacing a SM2VAV-8633 with our controller. The existing system is showing a fiber optic cable connecting this board with a speed control board SM2-FSP277/5. I was wondering if the SM2-FSP277/5 has a option other than fiber optic for fan control. Can it take a 0/10 volt signal. I thought I seen a manual on this but I can't find it now. It looked like a 0/10 signal was going to terminals 2 & 5 on the speed control board. Can I wire my 0/10 Volt signal to these terminals for fan control?
