Warning: please find more information on how to set the Starter up before install the device.
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.
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.
WARNING: please consider to consult a boiler technician to make sure which wiring is the most suitable for your heating generator.
FREE CT CONTACT (ON/OFF Relay)
To enable management of 1 CT free contact (without potential difference) of the generator, place the jumper in position 1.
Then connect the common electric cable to the COM terminal, number 3 of the Starter. Check the type of contact on the generator that provides for the connection of the room thermostat: if normally open, connect the second cable to the NO terminal (number 6) or if normally closed, connect it to the NC terminal (number 4).
2 RELAYS WITH 230 VAC OUTPUT
To have 2 relays with 230 Vac output (maximum switch 10A with resistive load and maximum 5A with inductive load) to activate hydraulic systems (pumps, valves, coils, ...) place the jumper in position 2.
The 2 relays will thus provide 230 Vac each output: be careful to connect the cables correctly so as not to damage the connected equipment.
The first CH relay of the Starter manages the heating of the system.
Connect the common electrical wire to terminal N, number 1 of the Starter.
If a normally open contact is required for voltage control, connect the second cable to the CH ON terminal (number 6). If, on the other hand, a normally closed contact is required, connect the second cable to the CH OFF terminal (number 4).
The second HW relay of the Starter manages the system's domestic hot water.
Connect the common electrical wire to terminal N, number 1 of the Starter.
If a normally open contact is required for voltage control, connect the second cable to the HW ON terminal (number 5). If, on the other hand, a normally closed contact is required, connect the second cable to the HW OFF terminal (number 3).
ANALOG 0-10V INPUT
Some generators support temperature management for heating via a 0-10V analog input: based on the voltage supplied at the output of the starter, the generator regulates the water temperature.
The working curve used is the following:
To use this function it is necessary to provide an external power supply to the Starter (in addition to the 230 Vac power supply): connect the ground to terminal 9 and the 12-36V power cable to terminal 8.
To have a 0-10V analog output from the Starter, connect the ground to terminal 9 and the other cable to terminal 7.
OPENTHERM PROTOCOL (active in 2023)
As an alternative to 0-10V, the Starter also supports an OpenTherm communication interface, as a master.
Through this communication, the Starter and the generator exchange information such as the required temperature for heating and domestic hot water, requests for switching on or off, operating conditions of the generator, alarms or signals from the generator, ... The Starter takes on the role of master, then goes to replace any generator master control unit: pay attention that diagnostic information may be lost.
For OpenTherm communication with the Starter, connect cable A to terminal 8 and cable B to terminal 9.
PROCEED TO THE INSTALLATION:
1. Apply the Starter to the back cover.
Pay attention to the correct connection of the contacts with the metal forks. Secure the device by screwing the screw into the hole at the bottom.
2. Restore power to the generator (or to the entire home, depending on the choice made previously).
3. Proceed to the device association in app.
