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. Więcej informacji zawiera Timed Force Objects .
When you release a forced value, the value returns to its normal status.
