Internal Timer With Constant Speeds / Prv Macro - ABB Johnson Controls AYK550-UH User Manual

A 550-UH User's Manual

Internal Timer with Constant Speeds / PRV macro

This macro configures for applications such as a timed powered roof ventilator
(PRV) which alternates between two constant speeds (constant speed 1 and 2)
based on a built-in timer.
Momentarily activating digital input 3 (DI3) provides a boost function which operates
the motor. See group 36, Timer Functions, for more information on setting up timers.
