Application macros 91
 Internal timer with constant speeds / PRV
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: Timed functions for more information on setting up timers.
For more information see Default values with different macros on page 279.
