The CH or DHW Boilers setting specifies how many boilers in a Split Cascade System will respond to a domestic hot water call.
CH / DHW Boilers
The CH or DHW Boilers always include the Master boiler. The remaining boilers will only respond to central heating calls. This allows the Cascade
0
System to satisfy both central heating and domestic hot water calls at the same time. At the completion of a domestic hot water call, the CH or
0 6
DHW Boilers will again be available to respond to central heating calls.
Press the LEFT or RIGHT buttons to adjust the CH or DHW Boilers setting then press the OK button to store the setting
The maximum number of boilers in a cascade is 4. Therefore, do not select a higher number than 3 in this menu as one should
never adjust to the same number as he has appliances in the cascade. This would override the Split of the system. Failure to
comply may result in faults in the cascade operation.
Through the Auto Rotation function, the number of burning hours is equalized over all appliances.
Auto Rotation
When the function is Enabled, the appliances will all run an equal amount of time. This helps balancing wear over the appliances.
Enabled
When the function is Disabled, there is no levelling of burning hours and the first appliances in the sequence will run more than the last one in
Disabled
the sequence.
Press the UP or DOWN buttons to enable or disable the function, then on OK to validate your selection.

Stable cascade operation requires that all boilers in a cascade System be the same size.
Mixing boiler sizes in a cascade System could lead to temperature fluctuations and erratic
cascade operation.
