11. ASSIGNING OF TERMINALS

The controller can work with 4 different types of circulating pumps:

11.1 High Efficiency circulating pump (WILO yonos Para series)

For PWM versions (without selector) it is necessary to connect the circulating pump signal
cable supplied.
For RKC versions (with selector) it is not necessary to connect the circulating pump signal cable
supplied.

11.2 High Efficiency circulating pump (WILO Stratos Para series)

It is necessary to install a relay to feed the circulating pump.
Installation of the relay will be by the customer and must meet the minimum requirements:
contact rated current >= 8A, rated voltage 250VAC, Contact material AgSnO2 or Ag/Ni 90/10.
Protection with fuse: 10/16 A, delayed or automatic fuses with characteristic C.
NOTE Each circulating pump needs specific wiring and parameterization.
Pay attention to the following paragraphs.
