Cascading multiple boilers
You can cascade up to eight NeoTherm boilers together. One boiler becomes the Master and
the other boilers become the Slaves.
Note: The system sensor and outdoor sensor will need to be wired to the Master boiler only.
The input from these sensors is used by the Master control to control the modulation rate of all
of the operating boilers it is connected to. If the Outdoor sensor is not used, the alarm light on
the SOLA control will be on, and the alarm contacts will close.
