Description
The Static Pressure Switch is an economical control for a modulating damper to control by-pass air. Preset at 0.2″WC and 0.3″WC, the SPS truly modulates the RDM/ZDM dampers to maintain the system static below 0.3″WC. Above 0.3″WC the SPS will Open the by-pass damper and below 0.2″WC will close the damper.
