1. Remove the rear plastic cover.

2. Insert the batteries into the battery compartment.

3. Select "Menu -> Devices -> Add device -> Smart Thermostat" in the app and follow the steps for pairing the device.

Table installation:

1. Snap the Smart Thermostat back onto the back cover.

Place the Smart Thermostat on a shelf.

Wall installation:

1. Remove power from the generator (Recommended: remove power from the whole house).
2. Check the power failure (in case of lack of appropriate instrumentation, disconnect the general generator).

3. Disassemble the previous thermostat and remember to take a picture of the connections present and to mark the wires.

The Smart Thermostat mounts a relay to enable the management of a dry contact TA (without potential difference) of the generator.

Identifies the 2 pole wires relating to the generator contact: they are marked as COM for the common and NO (or NO) for the normally open contact (or NC for the normally closed contact).

The Smart Thermostat works on batteries, so no cables should be connected to power the device. If there were cables to power the previous thermostat, insulate them.

Attach the back cover of the Smart Thermostat to the wall.

The cover has 2 holes for installation on the 3-module electrical box.

5. Connect the 2 electrical wires according to the illustrations shown and the configuration on the generator.

Pass the wires through the upper slot of the cover: then insert the cables into the relative cable glands and secure them with the fixing screws.

The common electrical wire must be connected to the COM terminal, number 1 of the Smart Thermostat. 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 2) or if normally closed, connect it to the NC terminal (number 3).

6. Attach the Smart Thermostat to the back cover.

Pay attention to the correct connection of the contacts with the metal forks.

7. Restore power to the generator (or to the entire house, depending on the choice made previously).

1. Remove power from the generator (Recommended: remove power 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) and remember to take a picture of the connections present.

Mark the threads by inserting stickers to distinguish them.

Remove any wall plate from the previous Starter.

4. Remove the back cover from our Starter.

First, unscrew the fixing screw located in the lower part of the device.

5. Attach the back cover to the wall.

The cover has holes for installation on the 3 or 4 module electrical box.

6. 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.

6a. 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).

6b. 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).

6c. 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.

6d. 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.

7. 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.

8. Restore power to the generator (or to the entire home, depending on the choice made previously).).

9. Select "Menu -> Devices -> Add device -> Starter" in the app and follow the steps for pairing the device.

Then go to the settings of the installed Starter and choose the desired mode (boiler relay, hot water relay, 0-10V interface or OpenTherm): configure the device based on the installation performed.
