Description of wiring
Factory-fitted actuators are wired to the terminal. If no valve actuators are factory-fitted, support terminals are available
for on-site valve actuators.
The AC fans used can be controlled between 5 stages via switched voltage terminals 230 V~, 50 Hz.
Control version *00M:
The built-in thermal contact automatically switches off the fan when it heats up impermissibly
and switches it on when it cools down again.
Control version *01M:
The built-in thermal contact is wired to terminals. It needs to be evaluated by the external con-
trol. When the thermal contact is triggered, the fan needs to be de-energised.

Note these points in the following wiring diagrams for Venkon AC with electromechanical control:
Comply with the details on cable types and cabling with due consideration for VDE 0100.
Without *: NYM-J. The requisite number of wires, including protective earth, is stated on the cable. Cross-sections are
not stated, as the cable length is involved in the calculation of the cross-section.
With *: J-Y(ST)Y 0.8mm. Lay separately from power lines.
If other types of cables are used, they must be at least equivalent.
The terminals on the unit are suitable for a maximum wire cross-section of 2.5 mm².
The
need to be respected when rating the in situ mains power supply and fusing.
