We are working on a hot deck cold deck system with pnumatic zone dampers. The cold deck damper is closed with no air preasure and the hot deck is open. The rooms have Johnson T-4002 201 single purpose high velocity stats. The problem we are having is that there are two actuators on one stat and the calibration is not going too well. We can't get the dampers to
modulate properly. I have tried to find info on the stats and all I found is how to calibrate them. Does anyone know if they can work a mixing box properly with two actuators? And would changing the spring preasure in one actuator help in any way?
Thanx in advance for any advice
