To view the currently programmed ODR curve, press <Show Line> on the ODR configuration
screen.

Additional parameters are available for Time of Day setpoint and boost; see Lead Lag Operation
reference manual for a full description.

8- STARTUP

To start the lead lag system:

1. Turn all boiler demand switches to LOCAL.
2. On the Master host boiler home page press VIEW LEAD LAG>Lead Lag Master to access the

Lead Lag Operation screen. Turn the <Lead Lag Operation> screen switch ON.

The system should now start when a demand is present.
