Controlling the pump from the appliance's controller
Control of the plant water circulation pump from the appliance's controller depends on
the power rating of the pump itself. 2 cases may be distinguished:
• Direct control from the controller with power absorbed by the pump less than 700
W. If the power absorbed by the pump is less than 700 W, make the connection as
shown in Figure 5.14 Electrical wiring diagram see page 50 and check that the jumper
(J10, located at the bottom left of the controller, above the "NO Contact" contacts) is
CLOSED, as shown in detail A.
• Direct control from the controller with power absorbed by the pump of more than
700 W. If the power absorbed by the pump is more than or equal to 700 W, make
the connection as shown in Figure 5.15 Electrical wiring diagram see page 51 using
a con trol relay. In this case it is necessary to OPEN the jumper (J10, located at the
bottom left of the controller, above the "NO Contact" contacts) positioning it as
shown in detail A of the Figure.
