Off - Verasys - LIT-12012370 - Building automation software - Verasys System

Shut down the system in the following two ways:

• Instant Shutdown: The application performs an Instant Shutdown on heating, cooling, and the fan when the input is set to Shutdown. Minimum On timers are ignored in this mode.
• Control Mode: The application performs a shutdown on heating, cooling, and the fan when the Control Mode input is Off. Minimum On timers are observed in this mode. Table 1 provides minimum on and off times for each stage of staged heating and cooling.
  Note: The SMART Equipment board can have additional Minimum On timers for the compressors that must expire before the equipment shuts down. These Minimum On times exist on the VEC controller. This instance applies even if instant shutdown or control mode was used to shut off the unit.

  RTU Stage	Minimum On Time	Minimum Off Time
