Configuration through micro switches
S1 - Hydro unit type selection
S3 - Modbus slave address and baudrate
* Default value
S4 - Degrees/Decidegrees (x10), temperature magnitude (ºC) and RS-485 termination resistor
* Only in the interfaces conected at both ends of the bus must be activated the termination resistor, not in the rest. The RS-485 bus can be biased through internal
jumpers JP2 and JP3. Consult the user manual for details.

Hydro unit type selection. It is recommended not to change the default value
unless you are sure about the Hydro unit type you own.
Normal operation: At device start-up, both LEDs are on during 5 seconds.
Afterwards only the green LED remains flashing (1900ms Off/100ms On). For
any other indication, consult the User Manual.
