1. Remove the power supply to the boiler (recommended: remove the power supply from the whole house);
2. Check the power failure (in case of lack of appropriate instrumentation, disconnect the general generator);
3. remove any previous generator control (thermostat or control unit);
4. remember to take a picture of the connections present;
5. mark the threads by inserting stickers to distinguish them;
6. remove any wall plate from the previous Starter;
7. Remove the back cover from our Starter.
First, unscrew the fixing screw located in the lower part of the device.
8. Attach the back cover to the wall:
The cover has holes for installation on the 3 or 4 module electrical box.
9. Connect the electrical wires according to the illustrations shown:
Pass the wires through the lower slots of the cover: then insert the cables into the relative cable glands and secure them with the fixing screws.
The power cables must be connected to terminals N and L: the neutral cable to terminal N (number 1) and the phase cable to terminal L (number 2).
With the Starter it is possible to enable the management of 1 free CT contact (without potential difference) of the generator or 2 230 Vac outputs to activate hydraulic systems.
Using the jumper on the back of the Starter it is possible to choose between these 2 configurations: to change the position of the jumper, lift it (do not rotate it) using a screwdriver (or other suitable tools) and then insert it in the desired position 1 or 2, paying attention to the metal contacts.
Press until the jumper is fully inserted.
The Starter is also equipped with a 0-10V analog output for generators that support dynamic temperature management (for this function, an external power supply, 12-36V, must be provided).
Finally, the Starter has an OpenTherm communication interface, as a master.
The Opentherm and analog output (0-10V) functions are alternatives to each other.
10. Proceed to connect the Starter to the heating generator.
