Forcing a Value
You force a value when you want to override a value, such as a value from a device.
When you force a value, all input from the system is overridden. For example, a schedule is set to start a fan at 09:00 but you want it to start at 08:00. In this case, you can force the fan to start at 08:00.
You can manually release a forced value at any time or you can automate the release, using a Timed Force utility object to specify the duration or end time of the force. Mer information finns i Timed Force Objects .
When you release a forced value, the value returns to its normal status.
In WorkStation, you can view the unforced value, which is the real value from the system, at any time. Mer information finns i Viewing an Unforced Value .
