Applications

• changes the output of a controller from direct to reverse acting, or vice versa
• with an amplified output flow, the relay can operate additional controlled devices
• converts Constant Air Volume (CAV) to VAV installations when using the RD-2000 Series Retrofit Dampers. In this application, the R-3030 automatically changes from direct to reverse acting when the input pressure signal increases above the factory set, field adjustable, input/output point.
• can be applied to sequencing applications on dual duct VAV installations
