I have 2 sites where we are using the comm4 driver. Everything works fine at times but I get a lot of stale data issues which keep the devices from going into occupancy and such. I have tried everything to no avail. Infocon has remoted in and made changes several times, it works for a little while and then goes out again. I think the issue might be poor communications wiring but just looking for some ideas. It seems some of you have good working systems could you just send me a list of the driver parameters you are using so I can see if that fixes things?
dllhvac, can you tell me what the range and output is of the Trane Velocity/Static pressure sensor is? I realize the sensor can output either velocity or static pressure based on a 90 degree rotation. I just can't find the voltage and velocity or static range. I tried searching around with no results.
the sensor has the output rating right on it i cannot recall offhand but the bypass damper cannot be controlled by the jace you must replace this controller with another the ccp panel previously controlled the bypass the new touch screen tracker has a comm4 communicating bypass damper that can be discovered and set
