Did a Phoenix air valve bacnet integration into a Jace the other day and my writable points do not have any effect on the system. Points on my end reflect the updated value but valve operation doesn't change. If I put valves to unoccupied the effective set point does not go to unoccupied set point. If I change the Occupied set point the effective set point doesn't change. Adjusting set point slide on wall sensors does cause change in eff. temp set point. Have Phoenix coming back out Monday but thought I'd throw it out there to see if anyone has ran into this before. Phoenix MacroServer via Bacnet IP
