Product Usage Instructions

Setting Up:

Open parameter r12 and stop the regulation.
Open parameter o06 and set the used sensor type.

Select electric connection based on the drawings on page
2.
Open parameter o61 and set the electric connection number in
it.

Select one of the preset settings from the table on the
right-hand side.
Open parameter o62 and set the number for the array of
presettings.

Open parameter r12 and start the regulation.
Review factory settings and make necessary changes in
respective parameters.

If using a network:
- Set the address in o03.
- Start scan function in the system unit.
