The measuringpoints in the room and reference room must be freefrom turbulence (no influence from room flow, no dynamiccomponent p d ).NOTE:If groups of rooms are arranged such that each successiveroom is at a different pressure level, then all transmittersshould function with a common reference pressure, e.g.atmospheric pressure.ReferenceroomRoomRoom pressure controlPrecondition for a room pressure control is that the room possessesthe required air tightness so that the desired roompressure can be obtained from the given flow volume differencebetween supply air and exhaust air. The level of roompressure that results from changes in disturbance variables aswell as the required correction time are dependent on, amongother things, the duct pressures in the supply and exhaust airsystems, the air tightness of the room and theair change rate (flow volume/volume).Room pressure settingThe desired room pressure is set using the ∆p knob.The setting range is from -20 to +20 Pa and -50 to +50 Parespectively.14
