4.5.2 Combining loads using "full mode"
To combine two loads using " full mode" :
1. Go to
> Advanced Setup > Load Combining .
The "Basic Mode" box is checked by default. .
2. Uncheck the "
Basic Mode " box. More parameters appear on the screen (may need to
scroll down): Initial Delay, Off Delay, Retry Delay, and Maximum Throttle.
Initial
Delay
Amount of time (minutes) between when the primary load is being serviced
and the secondary load is brought on to be serviced. For example, 5 equals 5
minutes.
Off Delay Sets a delay between loads to prevent loads from coming off-on. Default is 5
minutes.
Retry
Delay The system was unable to bring on a load because of a conflict with set
rules. Indicates the amount of time (default is 10 minutes) before the system
will attempt to service the secondary load.
Maximum
Throttle% If say the throttle is set at 75% (default) and the boiler is already running over
75% of it full fire the secondary load will not be allowed to be serviced at the
same time. Once the boiler is running below 75% of its capacity, the
secondary load will be serviced.

operation (while load combining is active), in our example Load 1- DHW> OK .
