Option menus
Zones Autobalance
The Zone Automatic Balance sub-menu memorizes the zones balance values once the installer has installed the balance resistors on the sensor lines. When using this system, a
resistor (
Figure 6
) without a predetermined value can be used to balance the line. Of course, if a line balance control is not used, this resistor can be omitted. Once all the resistors are installed, press the 1 key to store the all the balance resistor values in the CU.
Once the Zones Autobalance feature is enabled, any variation of the resistance triggers an alarm condition and is processed by the CU.
