1. In presence of cascade controller ODSP039 (optional), if
DHW production is managed by the controller itself, param-
eter P01 must be set to value 0. Parameters P15, P21, P25 will
be inhibited as they are managed directly by the controller.
2. By setting a value of parameter P01 other than 5 (heating on-
ly), the parameters relating to DHW production, i.e. P09, P10,
P11, P15, P21, P25, P30 and the DHW antifreeze functions,
DHW probe error and diverter valve anti-locking are enabled.
3. Parameters P26, P27, P28 relating to Modbus settings must
be configured only in the presence of the cascade controller
ODSP039 (optional), following the instructions provided in
the manual supplied with the controller itself.
