Water flow control enable during start-up
It allows the verification, at each switch on, of the correct operation of the circulator.

1. If the setting is changed, the change must be made on both
the master and the slave module.
2. To activate the DHW service, parameter P01 must be set to
the value 0 and parameter P32 must be set to the appropri-
ate value according to the DHW request device used (DHW
buffer tank probe OSND011, DHW buffer tank thermostat
or cascade controller ODSP039). Setting parameter P01 to
the value 0 enables the parameters related to DHW produc-
tion, i.e. P09, P10, P11, P15, P17, P21, P32 and the DHW anti-
freeze functions, the DHW probe error and the diverter valve
anti-locking function.
3. 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 and parameter P32 to value
2. Parameters P15, P17, P21 will be disabled as they are man-
aged directly by the controller.
4. Parameters P26, P33 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.
