11.2.3. Programming the master unit.
Menu Parameter Value
Control parameters COMBO ON to activate.
Control parameters Address 00
Control parameters Alternance ON to activate / OFF to deactivate.
Control parameters Alternance period Establishes the number of hours of continuous operation after which the pumps in the
unit are forced to alternate. The value 0 means 5 minutes.
Control parameters Start delay AUX We recommend setting 0 s.
IN/OUT parameters Min start irradiation In COMBO Solar operating mode with solar meter connected, it specifies the addition-
al irradiation value to the irradiation specified by the parameter Min stop irradiation
necessary to start another pump in sequence. It is advisable to set this parameter
equal to the irradiation value necessary for the operation of a pump in the group at
maximum power increased by 10%.
11.2.4. Programming of slave units.
Menu Parameter Value
Control parameters COMBO ON to activate.
Control parameters Address from 01 to 07.
Control parameters Alternance ON to activate / OFF to deactivate. It is possible to determine which devices are
included in the alternation and which are not. Devices excluded from the alternation
will receive a starting priority based on their address.
NOTE
To start or stop a unit in COMBO mode, simply press the START or STOP button on the master unit
only.
NOTE
To change the operating parameters of a COMBO unit, operate on the unit's master.
When the Master Menu is exited, the remote programming of the connected slave units is required.
In this manner, all parameters set in the master are also copied to the slaves with the exception of
parameter Address.
