8.5 Connecting the actuator
Connect the cable (suitable for damp locations) with a cross-section of min. 1.5 mm
2
to the
terminals of the controller output.
Following this, we recommend that you check the operating direction and the correct connec-
tion (polarity) of the actuator.
For this purpose, after you have connected the power supply, increase the reference value
for room temperature considerably for a short period. This should lead the controller to open
the heating valve with its OPEN control signal (+). When the reference value is reduced, the
heating valve should close with the CLOSE control signal (-).
8.6 Connecting the pump
Connect the cable with a cross-section of min. 1.5 mm
2
to the terminals of the controller.
